I'll grab some of that grease.If it doesn't have wrench flats you'll just have to hand tighten and make sure it's nice and snug until you figure out what muzzle device to use. Tip #1 is make sure you have proper roll pin punches and pin holders. It makes jobs like installing low profile gas blocks much easier... Tip #2 use moly grease/Aeroshell MS-22/anti-seize or similar on the receiver threads before putting on barrel nut. If you ever want to swap out handguards in the future, at least...
Also... if you use a suppressor, make sure your handguard gives you enough clearance to mount it. I made that idiot mistake on my 300 BLK build so now I need to buy a different handguard (it's too long and the ID of the rail is too small for my suppressor).
Thanks for the tip
