    Exactly. Short of some miraculous idea, you can't get a the desired performance from the AR-15 dimensions. It almost certainly has to be a new receiver/magazine/bolt group.

    Personally I think this would have been a better direction than the XM5 program.

    How much time do you have behind a 6ARC?

    To be honest zero.

    Moving along: I picked up my receivers this weekend, and I must say I’m very impressed with Stag. The lower is supposed to be a blem, but I can’t find anything wrong with it. The fit and finish is superb as far as I’m concerned. I suspect they are produced by Aero, as the address they shipped from is on the same street as Aero Precision In Washington state, but Stag is headquartered in Wyoming. This is not a complaint, as I feel Aero is a supplier of top notch receivers. I chose the Stag 10 receivers because I wanted a set of receivers that were forged, and featured the SR25/Armalite cut at the rear. These have a very tight fit between the upper and lower, and the machining is flawless. I couldn’t be happier, I think I found my new favorite large frame receiver set. Not to mention they came with takedown pins/detents, and were way less expensive than the Mega/Zev billet sets I’ve used on past AR10 builds. I partially assembled the lower with the supplied Stag takedown pins, and a mix of LMT/Colt/Forward Controls parts, and a Geissele SSA-E trigger. The buffer tube is LMT 308, with an Armalite AR10 spring, and Colt H3 buffer. The rest of the parts will have to wait until funds are available.
