Yes I know its missing a few pieces but at least I know the rest is on the way from Aero Precision. The heart of the rifle will be an Aero 308 lower, the M5E1 upper receiver/keymod handguard, their 308 NiB BCG, and 308 LPK. I hope to see the rest of the parts come in this next week. The barrel is the 18.5", .308 AR, Light Weight, 1X10 twist, chrome lined, match quality, by Criterion sold by Fulton Armory, with a Bully Brake from Overkill Customs on the end. 20 round Pmags and 5 round ASCs for hunting.
I've been reading as much as I can find in preparation for building this rifle and after reading about checking headspace I have a question about checking it on this barrel. On Fulton Armory's site they call the chamber a hybrid. "Our Hybrid Match Chamber allows use of .308 Win & 7.62x51 mm NATO Calibers" http://www.fulton-armory.com/barrelfatitan185lwcm1x10750gasblockchrome-lined.aspx
I know both .308 and 7.62 headspace guages exist. Which one would give an accurate indication of proper headspace? I only intend on using commecial brass/bullet handloads in it and not wanting to risk anything I thought I'de ask those with way more knowledge than I have.
