Retro Commando pistol (UPDATE)

[Bill Hollinger]

Factory Remington 55 gr and Black Hills 62 gr. Yeah, all of the above and they double feed. I did some research and it seems all the 11.5 SBRs and pistols are using the H (3.8 oz) or H2 (4.6 oz) buffers.

Not all.

My 10.5 and 12.5 run standard weight buffers. In fact, both are underweight by a couple of tenths of oz. Never had an issue with either, except when the gas rings were worn out.

The heavier buffer will help if your bolt is bouncing from moving too quickly from being over-gassed, otherwise it should just make recoil feel a bit softer. Was it operating "violently" when you experienced the FTEs?
