Installation Notes.
The AR-15 CompMag has a new locking system. Due to the new locking insert, it will fit tighter in your magazine well when compared to a regular magazine. This is normal, it will require some force to install and remove it.
1. When Installing the CompMag you will only need to turn the screw clockwise until you feel some light to medium resistance. You will not have to turn it very hard.
Over-tightening of the locking screw will cause the rounds to rub inside the magazine when feeding.
2. Once you have tentioned the screw, make sure the magazine does not pull out while pressing the mag release. If it comes out, tighten the screw slightly and re-check it to make sure it does not come out.
3. Put one round in the CompMag loading opening and slowly slide the round up and down in the magazine using the charging handle. If the round does not hang up, you are done. If the round hangs up when bringing it down, loosen the screw slightly, then go back to step 2 of the installation notes (above).

On the AR-15/AR-10 versions, when using the locking screw for compliance, if the CompMag is installed into the receiver with too much force, it can cause binding inside of the mag. Over tightening the locking screw can cause the locking insert to expand excessively and squeeze the magazine. This can cause both loading and cycling problems as the rounds may not feed through the magazine properly. If this is the case, simply loosening the locking screw can solve your issues.

In New York, often times a mag lock is installed on the firearm, which disables the mag release. Installing this too tightly will cause the same issue. You will know if you have one of these installed by pressing the mag release. If it does not press in, you have a mag lock device which prohibits the pressing of the mag release. The mag can be squeezed by the mag lock device if it is installed too tightly, and will result in the rounds or the follower not moving through the mag properly causing misfeeds. Always check the mag function before using epoxy on the maglock.


This video shows installation into a stamped receiver. For milled receivers you must purchase the milled receiver locking plate .This can be found under SHOP+, AK-47 CompMag Parts.

Note: the small bent wire form and button head screw that comes with your AK-47 CompMag does not need to be installed into the top of the magazine. This is an extra part we supply in case the magazine became loose over time from wear. We have not used it on any of our firearms.

Only the locking plate and socket head screw need to be installed.
