My 930SPX came from the factory with a choate extension and choate pistol grip buttstock and I added a choate oversized charging handle. choate is quality stuff and has performed flawlessly from day one. I have owned ATI parts and they are bottom of the barrel as far as build quality and fit & finish.
My opinion is that Nordic and Mesa Tactical are at the very top, then choate, then ATI at the bottom as far as ranking parts as Very best, good and cheap.
