You don't need a torque wrench to secure this handguard, using a regular adjustable wrench and tightening it down on a bev block is all thats necessary, Any person of average strength should be able to exceed 30ft/lbs and thats all you need to secure it provided you use a couple drops of loctite. Go look up accuracy and torque value tests for ar15 platforms and see that 30-40ft/lbs on a free float is not only more than enough, its ideal.

As far as aligning the handguard and upper, I see people complaining about the play in the metal dowel you insert into the gas tube, you can easily get around this with a mallet or anything that can tap, if you're an armorer you should have a nylon headed hammer anyway.

-First, hand-tighten the second barrel nut and give it a small nudge with the wrench for snugness, remove your wrench and check for alignment with the upper by dry fitting the handguard.

-Second, with the handguard still dry fit to the receiver, use your mallet or tool to nudge the handguard into alignment with the upper

-Third, remove the handguard and tighten the barrel nut a bit more, dry fit the handguard again and check for alignment, tapping into place if necessary; If you get to a point where the alignment is wrong but the upper wont tap into place, you just need to back the nut off a nudge and try again.

It should only take 2 or 3 dry fits of the handguard and tapping it back into alignment before you get to a point where tightening the barrel nut doesnt move the

bought this barrel on sale and threw it into a lightweight build, headspaced just fine with a cryptic coatings bcg and forster gauges, thought i would have tolerance stacking problems like the other review here, but everything worked first try no problem. got some nice vids of me shooting the rifle. had the chamber cut by patriot ordnance factory by purchasing their e-squared service, the necks of the cases have little black puffs from being pushed out w this feature, cheap effective barrel that was putting moa groupings with match ammo and a rest in windy conditions, no real need for a finer quality barrel unless you want to get scientifically accurate with all the rest of your parts or lock your rifle in a vise for shooting and really get serious, you pay exorbitantly for diminishing returns at that level, this barrel does it all for much less and to nearly the same degree as barrels costing 3x
