I will have to check with Aero tomorrow for specs on recoil system. Their website doesn’t show anything on specific recoil system specs. I just ordered the complete lower, and was told it was compatible with a proof barrel. The gas port shows .875 on barrel and the box it came in. Do you get an oversized tube?

Aero complete lower w/moe grip PRS rifle stock. Barrel and gas block are .875 w/ rifle length tube.

I just finished building a m5 .308. Won’t feed round to fire. I can place a round in barrel and BCG closes fine. It will sometimes feed several rounds after initial round fires, but not every time. When the next round goes into battery it sticks and is hard to get out with charging handle, requires two hands.
