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 !
Excellent bcg. Great price. No problems in my 300 blk. Wouldn’t cycle my 223 ammo though
