Semi-automatic AK-47's were available for purchase in Canada with
nothing more than an FAC (Firearm Aquisition Certificate) up until
1992. This was the year a fascist hag named Kim Campbell was used as
a sacrificial cow to railroad freedom-robbing gun legislation (Bill
C-17) into place. Legislation which--among other things--took away the
average citizens right to own a semi-automatic rifle which fell under
their guidelines for an "assault rifle." You can still aquire an AK-47
if you have a "restricted weapons permit." However, it's not always
easy or even possible to obtain the permit, and once you register a
restricted weapon you are also inviting the RCMP into your life. They
have the right to come and "inspect" the rifle whenever they want. Not
that they can't just enter your house anyway, but now you will have
agreed to it on paper. Anway, it's all going to get worse and you can
forget about it getting better.

So, for those of you who still possess one of these fun assault rifles,
here is how you can have even more fun with it before they come to take
it away. Converting a semi-automatic AK-47 to fully-automatic.
600 rounds per minute... ohh yes.

Materials Needed:

1 AK-47
1 twist-tie
and lots of ammunition

How it Works:

Stages of action in a semi-automatic AK-47:

1. Cock the rifle - The trigger Sear (the sear is the "catch")
holds the Bolt-Carrier in a ready-to-fire position.

2. Pull the trigger - The bolt is released causing the firing pin
to strike the shells primer thereby firing the bullet.

3. Piston comes back - Due to the pressure of the shells powder
exploding the "gas" piston is forced back moving the bolt-
carrier assembly along with it to re-cock the rifle.

4. Missing the trigger sear - If you are still holding the
trigger, the bolt carrier will miss the trigger sear and get
caught by a second sear behind the trigger sear. If you weren't
still holding the trigger the bolt-carrier would catch on the
trigger sear so you would have to pull the trigger again.

5. Release the trigger - The trigger mechanism causes the second
sear to release and the bolt-carrier moves forward stopping on
the trigger sear.

6. Now the process repeats at stage 2.

That's semi-automatic. Hmmm, if that second sear wasn't there
wouldn't the bolt-carrier just miss the trigger sear and if you held
the trigger it would just keep firing? Hell yes.

Procedure:

(It is obviously illegal to modify an AK-47 in this way. Don't!)

Remove the magazine from the receiver. Remove the Receiver Cover by
holding in the square button that sticks out the back of the cover.
Slide the Return Spring and the Bolt-Carrier with Piston assembly out
of the rifle.

Using the twist-tie, tie the second Sear back to the pin that runs
through the receiver of the rifle.

Now reassemble the weapon. Slide the Piston and Bolt-Carrier back
into the rifle. Slide the Return Spring back into the Bolt-Carrier
and slide the other end of it into its guide slot. Push the "button"
end of the Return Spring while settling the Receiver Cover back into
place.

Ammunition:

I can tell you that not all ammunition will work with an AK-47 in
this configuration. The problem is some ammo's primers are not
sensitive enough to fire when the firing pin comes back after the
first round is fired. In particular the military surplus ammo would
not work for full-auto. Go figure. Experiment with different brands
of ammo and you will find a brand that works.

The AK-47 does not fire from the open bolt (held back by a large protruding sear) as this post suggests. The AKS (and AK-47) fire from a closed and locked bolt (they're gas operated), and they are fired by a hammer striking a firing pin, they are *not* a fixed firing pin weapon. The only military weapon I know of which still fires from an open bolt with a fixed firing pin is the IMI Uzi.

The real process of the AKS/AK-47's firing process is as thus:

1: as the bolt travels forward (after being released the first time by the operator), the bolt carrier strips a round from the magazine and carries it forward into the chamber.
2: As the bolt carrier meets the face of the barrel, the bolt (inside the carrier) rotates to lock into place against the barrel.
3: As the trigger is pulled, the it acts on a sear which releases the hammer, striking the firing pin which in turn fires the round in the chamber.
4: Gases moving down the barrel are detoured down a gas tube, which force a piston back. This piston acts on the bolt, causing it to rotate and unlock, and further presses the bolt (and bolt carrier) to the rear of the receiver, at which point the process starts all over again.

If you want to convert your AKS to an AK-47, your best bet would be to try to file down on the sear. (If anyone has any ideas how to get an autosear (like the one in the M16A1/2/3/4) working in an AK-47, I'm all ears.)

THere are other ways, of course, this is simply the easiest one.
