Gun owners love clichés. One favorite that comes to mind is “you can’t make a silk purse out of a sow’s ear.” That one comes to mine sometimes when there’s a lot of excitement over putting advanced coatings on otherwise Mil-spec components. It seems like everyone’s got a nickel boron bolt carrier group for sale, but they haven’t stepped up the game much. If you really want a great bolt carrier group you can’t just take anything off the rack and give it a nickel boron coating. If you want exceptional performance from a NIB bolt carrier group, you need to start with the best. RISE Armament offers a Nickel Boron bolt carrier group for sale that’s built on a foundation of quality components, each one manufactured using the best materials for the application. The result is a Nickel Boron Bolt Carrier Group that you can really be proud to own.
The Right Materials for the Application
If you want to build a superior product, you can’t just keep doing what everyone else is doing. While Mil-spec products do the job they’re intended for, there is often a better way, something stronger, lighter or faster. RISE Armament began its manufacturing life in the oil and aerospace industries. They understand the demand for strength and precision in manufacturing and have translated that knowledge directly to their selection of materials for and machining of firearms components.
RISE Armament uses 8620 tool steel to make the carrier body for their NIB bolt carrier group. Heat treatment and case hardening give it the strength and durability for a long, worry-free service life. A shot peened tool steel extractor stands up to the demands of real-world operations, even full in full auto. RISE uses 9310 tool steel to build their bolts, for better than Mil-spec strength and performance. Even the CAM Pin is 4140 steel, the right material for the right job. Magnetic Particle Inspection ensures a flawless product that will give years of quality service. And yes, in the end, it all gets a beautiful silky coat of nickel boron, which brings with it performance enhancing self-lubricity and corrosion proof protection.
