Barrel nut torque and accuracy.

[markm]

I'd guess that truing up the receiver face would yield a better match up/lock up than going from 35 to 45 lbs, for example. It'd seem that a trued up receiver would require less torque to get a solid barrel/upper match up.

Truing the receiver face is nothing more than smoke smiths blow up your ass to make a few more bucks! An AR is NOT a bolt gun and never will be. Sorry Mark but I disagree with you on this topic.

It does align the bolt better for better life.

Align the bolt with what??? Bullshit! Quit drinking the coolaid.

Align the bolt with the barrel extension. This is the same reason that during testing, it was shown that free-floated rails increased bolt-life. Less flex, better alignment. It's also the reason some companies won't warranty their bolts unless you send them the receiver to be trued...or just buy a MEGA upper instead (ARPerformance being one such company).

At 25#, you can't notice it on 99% of setups (ie. Any setup not in a lab or competition ). At 30# it becomes a topic worth debating.

What do most people tq their suppressor mounts to. I feel like at least part of the tq range is sometimes over 30.

I hit it right at 25. I use Resbond 907TS. It's like Rocksett (holds to 2200+ F), but it is only moderately stronger than loctite 242 and can be removed using a crescent wrench without any heat, boiling water, placenta from a unicorn, etc.

But, don't get me wrong, it's on there. Has been a better solution than Rocksett for me.

I shoot for 20, go up to 25. You can go up to 30 before problems exist, really, but at 25+ you can measurably confirm bore distortion. 20-25# is plenty. All my shooting nearly is done suppressed. Rocksett is recommended, but honestly, I feel that it's optional. Proper torque is primo. More than enough...is not necessary.

Enlighten me please.
Not calling you out, just wondering what a Mega upper offers i could not get from a VLTOR MUR (for instance).
Is there a step in their machining others skip? Never seen his mentioned. Which of course does not mean much.
