Put together an 18" rifle gas system spr today, went to test fire a few rounds and the bolt doesn't move at all that I can see, doesn't extract the brass from the chamber, but I can pull it back and cycle it fine. Checked the gas block, seemed to be aligned fine. The dimples on the barrel lined up with the set screws. Friend thinks the gas tube is too loose in the block., After removing the gas block, this is the inside.
Is that a normal gas pattern or are the dimples off?
