I posted thison the "CVA Rifles" Forum , But I think the guys here have been at this longer so I will post it here because the NEF Handi's are very similar.
I recently purchase a CVA Optima Stalker rifle from Dicks in .223. When I got it home and inspected it closer, I noticed when the barrel locks up to the reciever , there is an obvious gap on the right side between the barrel and reciever frame. You can slide a piece of paper( maybe thicker) between the barrel and reciever about half way in. It appears to lock up with no movement , but the rear of the barrel is in contact with the reciever only on the left side. Will this effect accuracy or anything?
