AR Upper Question

[Elarski]

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.

If the gas port an block are in line, and the handguard is tight, then you are fine.

Thanks for the reply Steve. Puts my mind at ease. Yeah, everything lines up perfectly, now I just need to order an action block & a wrench for the float tube. I look forward to shooting a different caliber out of my AR (.300 Whisper); I'll post once I get it to the range.

I have a four rail gas block and a float tube on my .458 Socom upper and it looks just like your picture. You certainly wouldn't want them touching; that would defeat the purpose of the float tube. I think you are fine.

He is playing your song Steve. Did you ever buy that .300 Whisper ?

I just got a .300 "Fireball" from Model One Sales. So far so good.

444...

Tell me about this .458 SOCOM.
I might have to have one...
