(M)odular(R)ear(K)alashnikov(T)runnion for AKM/AK-74![]()
THIS IS FOR THE TRUNNION ONLY, ADAPTERS SOLD SEPARATELY
Our Modular Rear Kalashnikov Trunnion is designed to allow the installation of 1913 rails, M4 Stocks, ACE/Stormwerks Hinges and stocks, and in the near future wood stocks from IronWoodDesigns!
It Replaces your current Rear Trunnion and has adapters to allow you to use the majority of the stocks on the market!!
Go ahead and stake that castle nut because you dont need to disassemble the buffer tube to swap adapters! The bolt threads into the adapter from the inside of the receiver! You can swap back and forth between stocks in under 1 min!
These will be the #1 Choice for new builds as they allow you to be flexible later and not get stuck with one type of stock.
Drop this in a pistol build and install pretty much ANY brace on the market or Form 1 and SBR later!
Also compatible with the mighty WASR and PSA puzzle piece.
