I actually built the whole project and leave it intact. It’s got an 18 in bbl with mid length gas and it was the first AR I built with Midwest Industries full float fore end which I really like. I put a VLTOR stock with a nice pistol grip/trigger guard set up all in FDE. It’s very light, deadly accurate and so far very reliable.

I bought about 5 boxes of ammo; some Hornady and some PPU, and then Hornady dies, brass and projectiles. So far I’m only using 120-123 gr bullets and the trajectory out to 400 yards is impressive for not being a 3000+ fps round. I still have yet to CHRONY the stuff.

One thing I don’t like, not a big deal but, it dents the brass mid case I think against the ejection port.

My last build was a mid-length 5.56 w/ 16 inch barrel, impingement system. I had built three piston guns, to compare the CMMG, Adams Arms and Osprey Defense. The best system for simplicity is the Osprey. The most dependable and flexible is the Adams Arms. I had the CMMG in an eleven inch pistol kit. Good systems, but the impingement system is trouble free up to 600 rounds before cleaning.
