I'm posting this here in hopes someone has had a similar problem and can tell me what's up...
I ordered a .22 MRP barrel and BCG a few months back. I finally got a chance to go test it out yesterday but was unable to shoot it. I assembled everything correctly, used 3 types of ammo, the ammo feeds and seats just fine. When I pull the trigger, the hammer falls......but no bang. Round extracts fine, try again, and no bang.
I'm also having a problem w/ the 9mm conversion extracting after firing (fires, locks up the system - I have to bang stuff around and pull the lower/upper apart to manually get the brass off the bolt face) but I'm going to try some different types of ammo before I worry too much.
