Definitive Arms Custom AK
Definitive Arms Custom AK

For those who appreciate Custom AK variants chambered in .223 Rem/5.56 NATO, Definitive Arms is now offering their Kalashnikov System, a conversion that allows for the use of standard AR magazines. But this is far more than a simple adapter. This system is solidly built from CNC machined 4140 steel and permanently installed. It provides a last round bolt hold open and manual bolt hold open, simple push button bolt release and drop free push button magazine release.

The Definitive Arms conversion makes magazine changes virtually identical to the AR and much faster and easier and only ads a total of 3 ounces to a loaded rifle. The adapter (magazine well) itself is riveted onto the receiver not welded or screwed, which maintains the integrity of the AK design. There is a large push button magazine release on the right side in front of the trigger guard, similar to where it is located on an AR. The slide lock/release lever is on the left side just in front of the trigger guard and functions opposite to an AR. To lock the slide to the rear you push the lever down and you push it up to release it.
