Hey, building a new gun. I have a 1/4" riffe shaft that I'm using w/ the layout. In the future i may want to shoot a 5/16" shaft.

Before I set the mech. I'd like to know if all riffe/riffle-style shafts are milled to the same size at the trigger catch. Are they all 1/4" or is the 5/16" left at this thickness? This will effect how deep I can pin the mech.

Defo!Not sure on what measurment you need but I have a 5/16 riffe shaft that I can check for you.
