I don't have much info on this, but I was listening to the AR15 podcast and they were interviewing David Famigilette from New Frontier Armory and he let is slip (?) that they are working on large-frame Glock AR-lowers, bolts and barrels. I've previously built an AR-9 using their lower (it's a Joe Bob's, actually) and it's worked flawlessly with OEM Glock Mags and the new ETS mags.  I really had no interest in an AR-45 as I already own a Kriss SBR, but this kinda peaks my interest to do either a .45 or a 10mm. Disclaimer: I'm not affiliated with New Frontier, but I know there's been some interest in large frame ARs.

I'm going to x-post this in the Pistol Caliber Carbines section, but thought you guys would find it interesting.

If they build a .45 glock lower/BCG, and barrel...I'll buy them.

I would like a .40 bolt and barrel too.

I need one for my Macon Armory .45 ACP upper.
Love that upper!

Here is my QC10 build in 45acp using their large frame glock lower, barrel, and bolt.  I'm using a Heavy Buffers 9mm 12oz buffer and spring.  Cycles 100% and LRBHO works perfectly.  Currently using a KAK Shockwave brace and LAW folder.  Waiting to be SBR'd.

This is my Bazooka Bro. AR15-45 Carbine as I received it an this is how it looks now.   I changed the upper from a flat top to a A2 upper.
