Product Info for Midwest Industries Enhanced Nitride Bolt Carrier Group (BCG)

An amazing upper receiver starts with a quality bolt carrier group which is why Midwest Industries is proud to offer these top quality Bolt Carrier Groups. Midwest Industries manufactured these Bolt Carrier Groups from strong 4130 steel for the body, and add a nitrogen charge to the bolt to protect it from the damaging elements of the earth. You'll also find these Bolt Carrier Groups come with a Nitride bolt carrier coating which prevents corrosive elements from forming on the group and protects it from acquiring additional charges of nitrogen over time. A Nitride coating on this Midwest Industries nitride-treated Bolt Carrier Group serves as an excellent anti-seize coating, resisting carbon and other contaminates that may enter your firearm. You can be sure you're getting a top quality product with each and every order.image
