I often find mistakes in serious papers where a typist has put a B instead of an M. It can be quite a common mistake as the typist seems to think it is a large number, what difference does a letter make?

My plan is to stockpile canned goods. And then trade some of them, after such time that the grocery stores no longer have any inventory, for the fuelled functioning vehicle I'll need to get the hell out of town. Of course its been suggested that theres not much point in having a stockpile of food if you dont have the means to defend it. Thats why I am interested in finding this rifle. Maybe I should just focus on whatever firearms I can find, but I really had my heart set on an AKM

Forget about shooting those that mean you harm from 300 yards away with your MBR. Leave that notion to armchair commandos and 12 year old kids that pretend to be grown ups on the internet.
Some facts:

1. Those that want to harm you/steal from you don't come with a pirate flag waving over their heads.
   
2. Neither do they start shooting at you 200 yards away.
   
3. They wont come riding loud bikes or dressed with their orange, convict just escaped from prison jump suits, so that you can identify them the better. Nor do they all wear chains around their necks and leather jackets. If I had a dollar for each time a person that got robbed told me "They looked like NORMAL people, dressed better than we are", honestly, I would have enough money for a nice gun. There are exceptions, but don't expect them to dress like in the movies.
   
4. A man with a wife and two or three kids can't set up a watch. I don't care if you are SEAL, SWAT or John Freaking Rambo, no 6th sense is going to tell you that there is a guy pointing a gun at your back when you are trying to fix the water pump that just broke, or carrying a big heavy bag of dried beans you bought that morning.

PART III: GUNS, AMMO AND OTHER GEAR

After TSHTF in 2001, only the most narrow-minded, brain washed, butterfly IQ level idiots believed that the police would protect them from the crime wave that followed the collapse of our economy.
A lot of people that could have been considered antigun before, ran to the gun shops, seeking advise on how to defend themselves and their families.
They would buy a 38 revolver, a box of ammo, and leave it in the closet, probably believing that it would magically protect them from intruders.
Oh, maybe you don't think that firearms are really necessary or your beliefs do not allow you to buy a tool designed to kill people. So you probably ask yourself, is a gun really necessary when TSHTF? Will it truly make a difference?
Having gone through a shtf scenario myself, total economical collapse in the year 2001, and still dealing with the consequences, 5 years later, I feel I can answer that question.
YES, you need a gun, pepper spray, a machete, a battle axe, club with a rusty nail sticking out of it, or whatever weapon you can get hold of.
A LOT has been written on survival weapons. Everyone that is into armed survival has his or her own idea of the ideal gun battery. Some more oriented to a hunting point of view, others only as self defense means and others consider a little of both, and look for general purpose weapons.
Talking about guns, there is one special subject I want to rectify, and it's the point on what's the primary weapon for the survivalist, specially a urban survivalist that has to function in a society, yes, even after the SHTF.
The primary defensive weapon for the survivalist is his HANDGUN. It's the weapon that stays with him when he is doing his business around town of working on the field.
The survivalist IS NOT a soldier, even though you are a soldier or you once were the meanest mother on the battlefield, your home town is not a battlefield and it wont be, even if the SHTF. A LOT of water has to go under the bridge until the situation gets to a point where you can calmly walk down the street with a rifle on your shoulder.
People, if you are interested in real world SHTF situation, and you want to prepared for the real deal, then understand that this isn't black or white.
You wake up one day and listen on the radio that the economy collapsed and that the stock market closed indefinitely.
What do you do? You still have to go to the office/work/whatever .Kiss the wife good bye and walk to the office with your AR across your back, or across your chest, Israeli style, ready to shoot? You wont get far. Someone will shoot you or throw you in jail, or in a mental institution.
What I'm trying to explain, is that its ok to prepare for China invading you country, Germans and UN or Martians. That is the extreme, less likely worst case scenario.
There is an infinity spectrum of gray between the black and white. White being your average normal day and black being total TEOTWAWKI, lizard men invading the planet.
Rifles do have a place in the survivalist's arsenal, and a very important one. But you have to understand that 90% of the time, the handgun will be the weapon you have available when you need one.
You cant compare to a trooper in Iraq that has his weapon with him at all times.
I ask you how many soldiers do you know that keep wearing cammo and totting their M4s around town when they return home?
What works for war does not work for the survivalist, especially the urban survivalist.
Even if you live in a retreat far from town, you have to work, don't you? Or do you have employees that take care of all your mundane tasks, leaving you all day to keep watch with your rifle ready?
A soldier is part of a huge machine, HIS job is to carry that rifle, while others take care of other needs. A survivalist, one that is not part of a large survivalist group, has no one to cover for him.
When a new guy looks for advice on what to get for defense, some will recommend a rifle or shotgun as a first defensive weapon.
Lets say race riots start in this guy's city. He still has to go to work every day. What is he supposed to do? Shove his pump shotgun in his pocket? A handgun, even though less powerful, can be used for home defense AND go with you wherever you need to go.
If the place floods, he can still hop into an evacuation boat without leaving his weapon behind. I'm sure no rescue team will pick you if you are carrying a long arm. They'll ask you to leave it behind for sure.
What if your government, realizing that TSHTF and that they lost control of the events, bans all firearms indefinitely? Don't know about you, but if things are that bad, I'd like to be armed. You can hide a handgun under a jacket. You cant hide a long arm under your clothes.
I think it was Clint Smith who said that the handgun is only used to fight his way to his rifle. Man! that sounds "macho".
I'd love to see him walking into Walmart with his tactical M4, taking the subway, visiting the doctor or going to the bank.
"Over here Mr. Smith, you can hang you M4 right next to my coat" I don't think so.
Guys, unless you have your own shooting school, you do not get to carry your rifle to work.
OK, now that I got that out of my chest lets look at some options.

Handguns: Revolver or Pistol?
Pistol. All the way.
Yes, I saw the video of the guy that accurately emptied his S&W in ½ a second. I also saw the shooting range and the crowd behind him, watching the event. Can he shoot and reload that way if he is in his car, driving with one hand and shooting with the other, while a bunch of scum bags in another car are shooting at him?
Hey, maybe he can. I know I can't. Can you?
Generally speaking, the revolver is more difficult to master than the pistol. The double action is hard and it affects speed and accuracy. It can be done, but I found that pistols are easier, as did many shooters.
Also, even though they seem to be more simple, revolvers are not as rugged as service pistols, the mechanisms that cycles the cylinder and cocks the hammer is both complicated and fragile compared to auto pistols.
Before anyone starts casting evil voodoo spells at me for insulting their prized S&W or Ruger: I own revolvers and like shooting them, I just don't think they are the best option for self defense, and I see that everyone I talk to in my country who is worried about security as I am also chooses pistols.
Quality pistols resist sand, mud and dirt in general better than revolvers, where a small pebble locked in the mechanism may render the revolver inoperable.
I personally had a problem with a new stainless steel Taurus Tracker .357 magnum. After shooting it a couple of times I reloaded it and shot all 7 rounds as fast as I could and when I tried to empty it, I found that the empties were stuck because they expanded because of the heat. I had to wait until the gun cooled a little so I could empty the gun. Stuff like this can get you killed, even more in a 7 round handgun.
I once saw a man walk into a gun store wanting to trade his 357 magnum revolver for a 9mm high capacity pistol.
He said he was driving when thugs from another car started shooting at him. He was chased for a few blocks.
He said that he pulled his revolver and started shooting at them, and ran out of ammo real fast. He wanted more capacity and fast reloading. I could not agree with him more.
Some will consider this "Spray and pray", thinking that all rounds should hit the target and if some don't then it means that you need more time at the range.
Those same people will tell you that they intend to use bolt action rifles as defensive rifles, making each shot count, without ever missing their target, one shot one kill.
I don't agree with this. One shot one kill is ok for snipers, but the survivalist should have other alternatives.
I don't see anything wrong with shooting four or five rounds at a chasing car. If those rounds make them think twice about their intentions, they are rounds well spent in my book, even if they don't kill the attacker.
Suppressive fire is possible if you have a high capacity pistol. I wouldn't doubt on using such a tactic if it serves my purposes, or if it buys me time to get out of there.
Also keep in mind that criminals are cowards and therefore attack in groups. The survivalist should be able to face more than just one attacker. Getting into a gunfight with two or three armed men while packing a 6 round revolver is rather hard to deal with. A high capacity pistol can load about 15 or 19 rounds, and that can certainly make a difference in a gunfight where you are outnumbered.
A forensic doctor that used to live in my neighborhood got killed last year. He was ambushed when he exited a restaurant by 5 or 6 men. Even though they did kill him he managed to kill 4 of them and severely injure another.
He shoot regularly and carried a Glock .40. I'm sure he was lucky but I also think that his choice of weapon was also important in the outcome.
If anyone is wondering, people in my country that are serious about self defense carry Glocks. Those that don't have the
money for a Glock carry Bersas, FM High Powers or 1911 surplus .45s.
At first I wasn't sure about the Bersa, but once I tried them I saw that they are very descent guns. I now own two Bersas and am pleased with they performance.
The caliber choice calls for endless debate and it is not my intention here. Lets just say that 9mm , 40S&W and 45ACP are the obvious choices.
40S&W seem to be the most adequate, both in FMJ and HP, while 9mm lacks some stopping power and hollow points should be used if possible.
Though the 9mm lacks power compared to the 40S&W, it is more popular world wide, a factor to consider seriously when choosing a handgun for SHTF. Besides, 9mm can also be used in a number of carbines and SMG, another important fact to be considered.
SMGs and carbines chambered for 40S&W and .45 ACP are also available, but they at not nearly as popular as those chambered for 9mm.
Whatever you choose keep 500 or better yet 1000 rounds of quality ammo for your handgun at all times. 100 rounds wont last much if the crisis lasts long. Also consider that once the balloon goes up, governments tend to restrict guns and ammo.
Rifles
I previously stated that the urban survivalist will be using his handgun 90% of the time he needs to defend himself and family from attackers.
I didn't pull this figure out of thin air, it is quite accurate based on what happens here on daily basis, even a little optimistic. Cold harsh reality has shown us that most attacks occur when entering or exiting your home, when you are more vulnerable.
Almost no one is stupid enough to try to enter a barred house with armed occupants. Believe me people, the gene pool will clean itself rather fast once the SHTF.
So, is a rifle necessary? Of course it is! There is still that 10%, and that 10% can still ruin your day. And this percentage sky rockets if you intend to use that same rifle for putting meat on the table.
If you have to settle with just one rifle, go for a semi auto. Ideally you should have a bolt action one and a semi auto rifle. A bolt action and a semiautomatic 308 would make a nice combination.
Whatever you choose, try to keep it within military calibers, and military weapons if possible.
It may seem that I have something against bolt rifles but I don't. I think they are fantastic weapons, but I think that semi autos are much better fighting weapons.
The idea of "picking them out" 300 meters away with your bolt rifle, as they come in a row blowing whistles and firing warning rounds is laughable at best.
Bolt rifles do have advantages over semi autos, accuracy not being the most important one.
Bolt rifles such as Mausers last forever and are harder than rocks, THAT'S important. They are simple, easy to repair tools that will serve you (within their limitations of course) longer than any other weapon.
For example, the coil spring on my Mauser 1891 safety broke into 3 separate parts, after almost 100 years of faithful service. I dug into my tool box and found a spring left over from a kitchen shelve door. I cut it approximately to the length of the previous spring, replaced it and the rifle was fixed.
There are not many weapons that allow this. And it is a very valuable attribute once the SHTF and spare parts are no longer available.
Stick to common calibers, 223, 7.62x39mm, or 7,62x51 (308).
.223 vs. 308? I'm not going there. If you prefer 223 because it has less recoil, it's lighter, or you favor the AR rifle go ahead.
If you think that 223 is more powerful than 7,62.. sign up to Physics I.
Just remember what I said before, a survivalist is not a soldier serving in Iraq, and you don't have the entire USMF to back you up. You are on your own.
You are not going to pin your attackers down with a questionably effective round and wait until someone hits them with artillery. .
About ARs... I wouldn't trust my life to a rifle that has more versions than Rocky sequels... the way I see it, it means that the basic design was the problem and there is no solution.
On AK ... all has been said. The most popular rifle on the planet. And popular not because of politics, but because it works. It also fires an intermediate power, effective round, available world wide. SKS are also good, but I'd rather have removable magazines.
Again, don't use voodoo on me because I say I wouldn't trust my life to a AR. If you keep your weapon clean, know it's limitations and feel comfortable with it, go for it please. A couple of rounds of 223 will kill anyone just as well.

If you want a rifle that can do a little bit of everything relatively well, do yourself a favor and get either a M1A or a FAL in 7,62 (308) with a carbine length barrel. Preferably with a red dot scope and some kind of light mount. Leave full length barrels to hunters and bench rest shooters.
Do your homework on both guns and you'll see what I mean.
Choose 308 not because of the added range you can get out of it, but because of its power at all ranges, choose it because it turns cover into concealment. Think about all the possible cover material you can find in a city, like cars, trees, low walls and other structures. The 308 will go right through it, or destroy it after a few rounds. It's a proven cartige through out the years.

Shotguns.

Shotguns are good general purpose guns. The main advantage I see is the devastating stopping power and the ability to use special ammo, like slugs and less than lethal ammo. I'm not so sure about the role as an "inside house" gun. The muzzle blast is great and quick follow up are not easy, especially when adrenalin is pumping through your system or, even worse, when someone is shooting back at you.

Pistol caliber carbines and SMG.
If possible , I'd choose a SMG reduced to semi auto (only if necessary, of course, full auto selector is better if possible ) or other kind of short, small, pistol caliber carbine.
The combination of a 9mm handgun and a 9mm carbine or SMG reduced to semi auto or full auto class III has lots of advantages in my book and is a fine combination.
Some think that full auto is a waste of ammo. I don't think so, not if you know how to use your head, and use this feature wisely.
If you can get a short barrel and collapsible stock, you'll also have a weapon that can be hidden under a heavy coat.
A red dot scope would enhance accuracy a lot.
The advantage of having the same ammo for long and small arm is not to be taken lightly. From the logistical, survivalist point of you, this is one big thumbs up!
Think about cowboys and Americans that lived in the west, they also knew the value of using the same ammo for rifle and handgun. They had single action handguns and lever action handguns chambered for the same ammo, the modern survivalist can have the same ammo for his auto pistol and his sub-rifle as well.
Some think that a pistol caliber long arm is just one big clumsy pistol or a rifle sized gun that delivers pistol power and accuracy.
This is BS. Anyone that ever fired a pistol caliber rifle or SMG knows that they are much more accurate, hitting torso targets at 100 yards is easy, and a little more if you have a red dot scope.
Also, SMGs can manage hot ammo specially made for such guns, much more powerful than the one for handguns. Even if you use regular handgun ammo, the added barrel length adds a few extra feet per second making it more powerful. Just check the information on boy armor. Body armor that is rated to stop 9mm, for example, is not rated to stop the same 9mm ammo out of a SMG or carbine, because the added speed will make that same round penetrate the vest.
Anyway, +P ammo is more than enough power out of a SMG or carbine, you don't have to go looking for special SMG ammunition.
If you can get full auto, that one nice feature to have. Not worth it if you are on a tight budget, but if you can get it, it may come in handy someday.
Full auto SMG are giving police in my country a lot of headaches. A criminal with little or no training will put 3 or 4 cops armed with pistols and shotguns on their toes, just because of the sheer volume of fire these high capacity 9mm deliver.
There was this case of a bad guy standing in front of a patrol car full of cops on a red light stop, pulling a 9mm SMG out of his coat and emptying it on full auto. The cops didn't have a chance, he killed them all. The car looked like Swiss cheese with 40 9mm holes all over the vehicle.

SOUND SUPPRESSORS

All I'm going to say on this subject is : Have one if you can. That's it. I'll leave the rest of it to your imagination, don't make me say it.
Today it may seem like a "nice to have" feature... after the SHTF, it may be a "O God I've got to get a suppressor!!" feature.
I'd buy a good suppressor instead of a ultra high dollar scope like the ACOG. Buy a good quality scope, but don't spend a fortune on it, and use the rest of the money on a suppressor.
If you are serious about preparing for SHTF, you'll thank me one day, just trust me on this one.
9mm and 45 suppress quite well. Not as well as .22 , but there is much more power on the big bore ammo.
Combined with a full auto SMG, the possibilities are much greater.
Sometimes it's just better to go unnoticed, specially in a SHTF crisis.

BODY ARMOR
Dear God! Buy body armor PLEASE!!
It's dirt cheep in USA.
Preferably, get the police concealable kind( class II) Then continue to work on it and get class III A military armor and some rifle plates, just as you do when you start buying guns.
You'll end up with 2 or 3 sets of armor which are great to have for family members and spares.
Just so you know, I got so desperate about body armor I ordered it from USA through internet (bulletproofme.com), I ended up paying a total of nearly 600 USD for body armor that costs 200 USD in USA. Buy it while you still can.
When the SHTF you'll end up wearing it, believe me. I don't wear mine all day long but I do wear it when I have to go some place dangerous, deal with people I don't trust, or when I have to go teach Architecture Representation late at night, and must travel through a much dangerous road at 12 PM.

Physical ownership of precious metals (and no other kind of ownership may be enforceable during a dpression) can be problematic. Gold was confiscated without compensation during the last depression. You could own physical gold (illegally) if that happens again, but that's potentially dangerous and trading it becomes an issue so owning it may not help you much. I'd say silver would be a better bet if it's metals you're after, but at the end of the day you can't eat it and it doesn't keep you warm directly.  Capital preservation is the important thing, but it helps if you can store value in a tradable, transportable form that you're legally allowed to own.
