Ar10 troubles

Both mine run fine. But the lighter 20” version had accuracy issues. A lot of swapping and drama from BCA but they finally send a replacement upper that shoots good. It runs flawless so far but the brass was getting scratched and dented up pretty bad. After polishing the bolt lugs and putting a piece of sticky soft side Velcro on my shell deflector it cleared up the issue. The brass catcher didn’t do any favors to my spent brass either. Like I said the the CMC are goodctrigger for the money…but just cheaply made. They need to catch up to modern technology and update their housings. But..I can tolerate their trigger housing (and inconsistent travel) for the trade off of the one of the lightest budget AR trigger pulls available.
