1913 AK Master Trunnion

FOR IMMEDIATE RELEASE!! We are pleased to announce the new Colonial Armament PATENTED 1913 Master Trunnion for the AK47/74 series of rifles!!  
The Gen 2 models have increased chamfer around the holes to facilitate easier rivet seating and installation.

One piece CNC machined, no screws to lose or come loose holding your rail. Great for your next build, or add a 1913 mounting rail to your current AK with a simple trunnion  swap. Allows for mounting of a wide array of 1913 stocks, braces, and  accessories, turning your AK into a truly modular weapon.

Engineered to fit perfectly with no unwanted gaps here, 1913 rail is slightly  tapered to avoid misaligned stock angles. Made entirely out of  4140  steel with a black oxide coating.

Will drop into most full stock receivers and line up with existing holes (easy trunnion swap) just drill out current rivets, insert Master trunnion, and re-rivet.
