Assembling Grendel upper, would love any tips/tricks/info to help accuracy

[MikeinGa]

So... wanted to build an AR from scratch and loved the ballistics of the 6.5G so went that route. Lower is AA Grendel with LMT LPK, Magpul trigger guard, Timney 3lb trigger, overmolded grip, and Mako SR-25 stock with adjustable cheek weld and built-in monopod.

Upper is AA Beefy Squared side-charging receiver, 20" Satern fluted barrel, EGW gas block (clamp-on), Midwest Industries lightweight quad rail 15" hand guard

I've heard a couple tips for assembling the upper, that I should first use loc-tite primer on the inside of receiver and barrel shank, then a very thin coat of loc-tite blue when assembling to bed the barrel, and clean out any residual with more primer.

When assembling, clean the threads, then a bit of moly grease, then torque to 60, back off, torque to 60, back off, torque to 60 and then turn to next available port so gas tube aligns properly

I don't plan to bed the gas block.

Anyone have a tip how to keep the upper receiver secure in a vise? it doesn't fit in a standard upper-receiver block...

Thanks!

Here's a mock-up (lower assembled, upper gently screwed together to see what it'll look like)

First I would not use loc-tite primer or blue on a AR barrel due to the high heat. I use loc-tite C5-A anti-seize on all threaded parts. To get the barrel to fit tight and line up with upper, you must lap the upper square to carrier bore. I have found that this helps to get lower sub-moa's. I also use adjustable gas blocks to control the bolt opening and carrier weight system to control the cycling. If yuo have any questions e-mail me. That's IMHO.
