your thoughts on an ar short stroking

[UncleDano]

It's obviously under gassed but the best thing you can do is give it to somebody knows how to build ARs and have them double check everything. It could just be the gas hole is undersized which is not uncommon.

since the rifle buffer weighs more than most carbine buffers it still could be op'd. the extra weight of the buffer helps out. i don't have a single faxon barrel (223w, 6.5creed and 308win) that ISN'T op'd. the creed and win were the worst in op than the 223w (minimal extra weight required). maybe they (faxon) does the military type ports to ensure it will cycle? still, it's short stroking and that really over pressuring from what i remember?

rereading page 1

rifle buffer works fine, carbine doesn't..........that means it's overriding the next round and can be fixed in 1 of 2 ways (possibly both).

1) use an adjustable gas block
2) install a heavier buffer (h3-h4 possibly)

most standard weight of a carbine buffer is ~3ozs. that's almost half the weight of a rifle buffer.
