AK-74 Magazine Extensions for 5.45 and 5.56 magazines. Most magazine will fit plus 6, some may only fit 5. Made from 6061 Aluminum. Proudly manufactured in Utah.

Does your Kalashnikov Rifle Match Director design stages around 30 round AK magazines? Take a few make up shots with 6 more rounds in your magazine. Not a competitive shooter, eh? Reload less and look cool at your local range with these mag extensions hanging off your rifle.

Magazine extensions were designed to be as thin as possible, without compromising strength, to not add unnecessary weight nor space to your range bag or rig.

Comes with mag extension and screw to lock extension. You may have to remove a little material from the front of magazine to allow clearance for the screw.

Confirmed compatible with magazines listed below. List will be updated as more magazines are found to be compatible.

    Shipping was fast, items came well packed, very straightforward instructions for installation, and the fitment on 5.56 circle 10s are excellent. I'm a little curious about the possible need for replacing springs but will find that out when testing occurs.

    these are great ways to get more rounds for your 5.56 aks. Mine have worked flawlessly and it’s an easy install!
