The NLA AR15/M16 Enhanced Bolt Carrier Group provides improved function and operation via several key improvements. The expanded rear of the carrier allows for smooth cycling in the buffer tube. Major internal parts are coated, including the firing pin, cam pin and extractor.

The extractor (machined from raw stock not cast) includes a black insert and o-ring for reliable extraction.

Gas key screws are hardened Grade 8 and are properly torqued & staked. Bolt is machined from SAE 4140ph high-grade steel. This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure and providing a long service life.

Bolt is shot peened and MPI inspected. Carrier is machined from 4140ph steel to aerospace tolerances.

DLC Finish

The DLC coating gives excellent protection against abrasion, tribo-oxidation and adhesion (scuffing). The coating permits surface pressures that, under normal conditions, would lead at once to scuffing and cold welding. Friction losses are reduced to a minimum. The good corrosion resistance protects the substrate from destructive attack.The Rockwell hardness on the outside is double a Phosphate BCG.

Nextride Finish

The Nextride Treatment provides improved function and operation via several key improvements – AMS 2753 specifications – Pyromtery per AMS 2750 – Hardness 52-58 HRc – Improves fatigue strength – Exceptional Lubricity – Low coefficient of friction – Improved Wear Resistance – Improved Corrosion Resistance – Resistance to weld spatter – Holds dimensional requirements with little or no distortion – Nice matte black color – Metal treatment (not a coating). The nextride finish provides superior lubricity and hardness, and the expanded rear of the carrier allows for smooth cycling in the buffer tube. Major internal parts are nextride treated, including the firing pin, cam pin and extractor.

Nickel Boron Finish : NiB

The nickel boron finish provides superior lubricity and hardness, and the expanded rear of the carrier allows for smooth cycling in the buffer tube. Major internal parts are nickel boron coated, including the firing pin, cam pin and extractor.
