So.. I have a Bushmaster carbine with a non-H buffer, A BCM 16" middie with an H buffer and a BCM 20" rifle length with an H buffer (got the uppers and lowers separately). Maybe I should swap the buffers between the Bushmaster and the 20"? I did stake the key and the castle nut on the Bushmaster and upgrade the extractor spring , etc with a BCM kit. I plan on unloading the Bushmaster on a sucker.
Comments?
