Sons of Liberty Gun Works Extra Power Rifle and A5 Buffer Spring

Sons of Liberty winds this action spring about ten percent stronger than a standard rifle length spring, which is the fix for an over gassed gun slapping the buffer harder than it should. More spring pressure slows the carrier down, softens the impulse at the shoulder and keeps a suppressed or heavily gassed rifle running inside the window it was built around.

It works with A5 and intermediate length buffers as well as standard rifle length buffers, so it covers both a classic rifle stock setup and the A5 receiver extension a lot of builds run now. The wire is passivated stainless steel and the spring is finished black so it is easy to pick out of a parts bin.
