I don't have any gripes about the little rifle. I use iron sights, run factory ammo through it, and have good magazines. It's accurate, dependable, and handy.
I think Dennis nailed it, accurate and dependable. I have a old A1 BM and a M4gery BM when they first came out. Both run great, I use M193 mostly, made some changes on both but still using the original BCG's and barrels.
Take care of these four items and your AR should run like a Swiss watch.
This BM is almost a antique.
This BM well be due for a new BCG in another few thousand rounds.
