Just finished and test fired my Olympic barrel assembly on a RRA lower. Is it unusual to find Olys with the gas block in the pistol location? Mine is there and unmodified it cycles fine with subsonic and supersonic loads.
Sub loads are: 220g Sierra, modified 221 brass, 8.6g H110 powder, Rem 7 1/2 primers.
Super loads are: 110g ? HPs, modified 221 brass, 19.0g H110 powder, Rem 7 1/2 primers.
I was more than willing to fiddle with my new toy if it didn't work, but it has been working fine with both loads.
