I have located and modified a nylon “ spacer” as sold by Home Depot. The original model is 1” long x 1/2” diameter, with a .257 bore down the center. I trim 3/8” off as the full 1” length does shorten a complete recoil cycle. So with a 5/8” length piece, the bolt, piston extension and striker seem to maintain their full recoil. Will test as I get time and update. This is particular to the Historic Arms Guns as Len builds them with the original recoil buffer removed, due to his striker spring design. This piece sits over the recoil rod, inside the striker spring, and should provide some buffering between the striker, et all, bolt and piston extension and the rear of the trigger frame.
Will post a pic of said product soon. But if you go to Home Depot website and search for “ nylon spacer” look at the 1”x1/2”x .257 ID version.Information
