The last mention of the 'lock ring' (5:45) was to loosen it then to thread handguard, then no further reference. Not much on the purpose, tightening, et al of the lock ring. Is there a gap between the top (extended) handguard rail and the upper receiver rail.?
If I have a low profile gas block already may just install it the same way with the barrel nut?
It is so possible that one may have to "shim" to achieve perfect alignment. I wish you had included that with this video.
I have run into that a couple times on different handguard/rail systems.
I appreciate the great instructional video. Just a quick question… What was the point of tightening to 30ft-lbs. three separate times (5:17)? Also, I could be mistaken but I thought the torque limit on the barrel nut shouldn't exceed 35ft-lbs. .
Music is too much.
HOW DO I TAKE THIS OFF. HOLY CRAP IT WONT COME OFF
Length of rail?
Wow..
Hbar barrel? Nasty. It makes the gun front heavy. Dump that crap
No offense, but your voice reminds me of Jarvis from Iron Man movie.
What length hand guard is this?
Nice vidio thanks ,but that music can really go i could hardly hear over that .head banging music in an instructional vidio is really stupid .
How much should this cost at a gun smith?
Nice, well done video! Makes it look easy. The written instructions say, however, that a direct-impingement AR can never be fully floated, so is the one in the video DI or gas piston?
How long of a gas tube is it. What size barrel
what kind of barrel nut.
Will the 12" mod work on my Ruger AR556 carbine, if I replace with a low profile gas block?
