Most Recent Reviews Bcg .308 left handed by William Major, Verified Owner, December 24, 2024
Excellent fit and finish on this DLC- Diamond like carbon- coating
Most Recent Reviews LH Johnson bolt by Kirk Jones, February 28, 2020
So far the LH BCG has performed well. The only complaint is that the carrier is semi auto cut and I would prefer to have more material there. I use it in a .308 chambered rifle and it doesn't hurt to have the carrier, as solid as you can make it.

Product Info for Next Level Armament NLX .308 AR-10 Complete Bolt Carrier Group

We use aerospace grade steel and precision machining to create the best Bolt Carrier Group for your AR10 build. Was included machined billet extractors and MPI Bolts to ensure that your Next Level Bolt Carrier Group keeps you shooting trouble free for years. The NLX 308 AR10 Bolt Carrier Group for Right/Left Hands provides improved function and operation via several key improvements. The expanded rear of the carrier allows for smooth cycling in the buffer tube. We coat all internal parts including the firing pin, cam pin and extractor. Each NLX 308 BCG contains a hardened, shot peened and MPI inspected bolt. We machine the bolt from SAE 4140ph high-grade steel. This material provides an extremely hard surface and a strong core resistant to structural failure. Machined from 4140ph steel to aerospace tolerances, the carrier is strong and durable. We stake the gas key to mil-spec tolerances.image

Whether you hunt, spend the day at the range, or shoot for longer range accuracy, the NLX308 AR10 Bolt Carrier Group delivers trouble free, long lasting performance for your rifle. And the DLC coating provides superior protection against abrasion, tribo-oxidation, and adhesion (scuffing). Normal wear and skuffing under high pressures are greatly reduced. The reduced friction creates minimal wear on your BCG. The good corrosion resistance protects the substrate from destructive attack. With Rockwell hardness on the outside double that of a standard Phosphate coated BCG, this BCG leaves other BCGs behind
