Any issue with over torquing the barrel nut? SLR recommends 35 ft/lbs on all ar handguards.
I noticed that you didn’t dimple the barrel for your gas block retaining screws. Have you ever had a problem with the gas block moving after firing your rifle?
Wouldn’t anti seize be a better option as the grease will melt away with heat?
What about head space
Great video. Just finishing my kit and the dust cover won’t stay shut. I’ve tried a second one with the same issue. Do you have any suggestions? Thanks
Do you know of any manufacturers that offers a very heavy barrel like that?
This is awesome, thanks for putting this together.
Great video. Just a note: spacing the gas block for a GI handguard retainer is only necessary for military contour barrels. The spacing is not necessary on most modern sport rifle barrels which are designed for free float handguards. Using a dimpling jig is the best and easiest way to insure best gas block alignment. These dimpling jigs can be purchased online for about $35. This comment is meant as an extra note not a critique. Again, great video. Thanks for posting.
Never use a torque wrench to loosen bolts. It will do it, but you will throw you wrench out of speck faster.
Wow people love to grease everything!
I actually feel confident on building a upper part by part , but one thing is how come some people leave out a small part of the gas tube stinking out and yours is aline to the screw
Where can I buy holy moly greaseš
Congrats. When you apply grease to the threads you complete screw up the torque spec. Always a nice thing to do on a high powered gun!
The grease on the threads change the torque value
Did you just use your torque wrench to loosen the barrel nut?!!
So what is gas block timing. I bought all aero precision parts.
Great video man. I have built lots of these and watching for fun. Spot on!
Short, sweet, right to the point. Just what I needed. THANKS BRO!!
I absolutely hate the roll pin on the gas block. It’s so awkwardly shaped, I had to duct tape mine to a table with a spacer under the lip so the pin can be hammered in at a level angle.
nice demo man. also fuck youtube.
Me with a Troy handgaurd that fits on old school barrel nut ššš
Is the torque spec for dry or lubed? Because you need to modify the torque if it’s spec for dry or else you can easily overtorque. 65 ft lbs with lube is closer to 80-100 dry
Looking at building my first AR soon. (Own a prebuilt one now, want to build my next). Anyway, maybe it was just too fast and I missed it but how do I know the gas block is over the gas hole in the barrel? Also, does the Gas tube have a certain depth it goes back into the reciever? Or is it able to be moved so you can get the block over the hole properly. Thanks.
In my experience the gas tube always comes with the roll pin. I have damaged them and they can be hard to come by if that happens. Keep extra on hand before building.
Holy Molyš
I wouldnt really use blue loctite on the gas block. It heats up pretty quickly. You might need to use a set screw. And then stake that. Loctite is affected by heat and the gas block is the hottest part.
Thanks for the lesson. I’m a very beginner and just bought a 7.5" ar-15. I wanted to change the muzzle brake (looks like there’re many options that is better than birdcage it came with) but the part I need to unscrew is bit inside of the hand-guard (just inside to piss me-off, sorry). Is there a way to unscrew the birdcage w/o the taking whole damn hand-guard off? I appreciate your response in advance. Thanks!
Thank you for the video. But I see something you did wrong. Sorry! Youāre not suppose to loosen a tightened nut with a torque wrench. If you did that when I was in the Navy that wrench had to recalibrated.
You are aware that you only need to set the torque wrench to 30, loosen it, 35, loosen it again, set it to 40, and then you have fitted the barrel nut adequately…. Also, you forgot to dimple the barrel, when installing the gas block?
That glass block is cool; however, I recommend something that you can adjust without tools when you cake it up and need more gas to avoid failure to eject/load.
what make is your handguard? and do you have to purchase a particular barrel nut that corresponds to the handguards?
Who started the myth of stretching threads lol š. Torque it and forget it
Do you think brake caliper grease would be good because it is rated for high temperatures?
what grease are you useing?
Where can you find that barrel?
Should never look down the barrel smh…. jk good video Iām late to the party š
@15:43 you can hear some sort a demon moan
did your barrel not have gas block dimples on it for the 2 set screws?
You Never use a torque wrench to loosen.
