Ok, i know I have posted a few questions but here is one more. Installed my barrel but I don’t “think” it is completely flush, the barrel flange being flush with the receiver. There is a very, very tiny gap between the two. I have everything installed, handguard, gas block and comp. this is a picture I have looking inside the receiver. From looking at the pictures does it look good or should I take the handguard back off and try and get it flush? I do appreciate y’alls help and advice. Learning a lot here especially assembling my first one.
