Here's my new Grendel. Bought a new basic AA upper on gunbroker and slapped a lower and scope on it. First range session and it ran like a piece of crap. No bho, wouldn't even strip another round from the mag using factory hornady. Didn't really bother me since I was going to free float the barrel and use a low profile gb. Once I did free float it , I still had cycling issues with hornady ammo, but it runs flawlessly with my reloads using 30.5gr of cfe. Accuracy is good, about an an inch with factory ammo and a bit tighter with reloads. 5 shot groups.
Factory rounds do cycle well with my can though. I mainly bought the ammo for the brass. It's cheaper to buy loaded ammo then it is to load from new components!
Specs
Factory AA upper
Troy rail and irons
AAC 51t fh
Bobro mount
Leupold mark ar 4-12
Noveske lower w/geiselle trigger
