Building an upper for the first time on my own...
The upper is going to have an aluminum free float tube, and JP Adjustable Gas Block. When I screwed the barrel, free float tube, and gas block together by hand, there was almost a 1/4" gap between the gas block and the free float tube. My question is, am I missing something here? I have a 20" Bull Barreled Upper, and there doesn't seem to be as large a gap. Maybe I'm just paranoid, but I'd rather ask a stupid question than f'up my project. Thanks in advance for the help.
