The Ultimate Light Precision AR Project
AP Custom uses a standard barrel nut, so just add the 1.4oz to the finished weight. But again though you'll want to ask for rail mount vent slots all along 3,6,9,12 o clock, since I believe it's missing the bottom slots I think. That'll reduce the weight just a bit further too. And I believe...- Hygienist

Yep, the Heavy Duty is a specific model. http://megaarms.com/ar-15/upper-receivers/billet-uppers/sbu-billet-upper-wo-ch-slot/ As you can see, it weighs 13.4oz, vs Mega's standard billet upper which weighs only 9.4oz...- Hygienist

Jp Low mass is going to be inappropriate with the switch block I think. I'm fairly sure though not 100% that it only has normal gas and suppressed, which means it'll either be over gassed or under gassed. I see you choose the JP silent capture as well.

Gunsmithing Speccing AR10 barrel: Gain twist, taper?
I'm ordering an AR10 barrel, the blank which I'd like to get from Bartlein. It'll be a 16.5" .308 Winchester bbl. I'd read that the top competition shooters are starting to use gain twist, and I'd like to look into it if I can get more info. I'd like to go all the way up to using 208 gr...- Hygienist
