I would recommend to anyone
So happy with this BCG I bought another and I'm ordering another soon. My AR's run smooth like butter now. Love it.
Precision made operates smooth
I PICKED UP THIS BCG FOR A SPARE & SWAPPED IT OUT IN A RIFLE I HAD A NITRIDED BCG IN. THE NI BORON BCG WORKED SO WELL I DECIDED TO LEAVE IT IN THE RIFLE AND KEEP THE OLD BOLT FOR MY SPARE ! YOU JUST CAN'T BEAT A NI BORON BCG FOR THE PRICE !
Works great in my 300 blk. Wouldn’t cycle 223
This bolt runs like butter in my receiver. Head spacing was spot on and the price was great that’s why I bought 2 of them
Haven’t had a chance to try it out yet but it sure looks great. The fit and finish are first rate and I’m glad I picked it up. If there’s any problems, down the road, I’ll change my review but so far so good.
Look amazing in my ar 15
