RISE Armament AR15 Bolt Carrier Group - Nickel Boron Finish
$259.99
RISE Armament AR15 Bolt Carrier Group - Nickel Boron Finish - When it comes to your AR-15‘s bolt carrier group, reliability is key; that’s what you get with RISE Armament’s advanced Nickel Boron Bolt-Carrier Group (BCG): reliability. So why is nickel boron so great? For that, here’s a little science. Nickel boron (NiB) is a columnar-formed compound. It’s about 95 percent nickel and 5 percent boron. Due to its formation, it reduces contact points between surfaces. However, it still provides an additional layer of hardness to the steel. Because of the reduced surface contact—given only the rounded ends of the NiB column’s touch—it acts almost like a lubricant.
