Featuring DS Arms NPE Nickel Phosphate Coating

The DS Arms Low Mass ESC - Enhanced Sand Cut complete bolt carrier group is the pinnacle of AR15 - M16 bolt carrier group production. We took our standard Mil-Spec bolt carrier group and upgraded with real world no-nonsense features that make sense, not just make it flashy! First and foremost we looked to our roots in the FAL Battle Rifle and incorporated L1A1 style sand cuts on the all of the load bearing surfaces of the carrier. These sand cuts allow any sand, dirt or debris that may have gotten into the action to easily be cycled out. After the sand cuts we knew we would have to give this bolt carrier group a finish that puts function over form, the durable NPE Nickel Phosphate Coating we selected for this complete bolt carrier group will provide resistance to wear, corrosion, rusting and pitting.

The DS Arms AR15 M16 Cut Complete Low Mass Sand Cut Enhanced Bolt Carrier Group with NPE Nickel Phosphate Coating is perfect for your next build. We machine these assemblies using the latest manufacturing techniques, material and finishes. The carrier is shot peened 8620 Steel and the bolt is MPI 9310 material. This complete AR15 M16 Cut Complete Low Mass Sand Cut Enhanced Bolt Carrier Group with NPE Nickel Phosphate Coating includes the complete bolt, complete carrier with properly staked gas key, cam pin, firing pin and firing pin retaining pin.
