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...

Not really! He said: " i have another lower with an a2 stock and the 22 arc runs just fine on it, it has a rifle buffer weight. (6")"

Hey foxhunter, any luck on resolving the problem as yet?

?

Any update from the OP on what has been tried so far?

Here is some in stock and cheap. PPU is good reloadable brass - tried it before...

"The dishonest" what?

You'll note that all selections show 'Out if Stock'. :(

I don't recall you mentioning whether you were using a 55gr or an 88gr. bullet loading.

if the carrier is dragging on the gas tube it'll act like undergassing, so making sure the tube to key alignment is correct. not only...

Right!

If it is under gassed and leaking at the gas block, then why does it perform perfectly with the A2 stock (w/heavy buf) installed?

Sorry, but short stroking is not only related to not getting enough gas! If it is ejecting at 4:00 o'clock, he is not under gassed, but...

Yes, Get an H3 or heavier buffer and give it a try. Report back.
