NLX 6ARC DLC BCG- A Premium BCG for your 6ARC or 6.5 Grendel rifle.

Whether you shoot for fun, hunting, or rely on your rifle for self defense, you want a reliable Bolt Carrier Group.  The enhanced Next Level NLX 6ARC DLC BCG provides improved function and durability through several integrated improvements over other BCGs.

Next Level produces each carrier from 4140ph steel to aerospace tolerances.  The expanded rear diameter of the carrier allows for smooth cycling in the buffer tube.   We use machined extractors , not cast, and we include a black insert and O-ring during assembly for reliable extraction.

We machine each bolt from SAE 4140ph high-grade steel, then shot peen and MPI inspect.  This grade of steel combined with our DLC coating provides an extremely hard surface and a tough, ductile core resistant to structural failure and providing a long service life.  We coat all internal parts with DLC, including the firing pin, cam pin and extractor.  During assembly we torque and stake hardened grade 8 gas key screws to mil-spec standards.  

Add a Helix 6 Carbon Fiber barrel to the NLX 6ARC DLC BCG for premium performance, accuracy, and reliability for your rifle.

DLC Finish

The DLC coating gives excellent protection against abrasion, tribo-oxidation and adhesion (scuffing).  The coating permits surface pressures that, under normal conditions, 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 that of a Phosphate BCG.  Our most popular finish, DLC cleans easily with a quick wipe down.  

The NLX 6ARC DLC BCG is also compatible with 6.5 Grendel.
