DLC bolt carrier group for 6mm ARC and 6.5 Grendel AR-15s, built to the same spec list as the NLX556 DLC group.

Compare current prices and availability from retailers we work with.
The NLX 6ARC DLC BCG is Next Level Armament's bolt carrier group for 6mm ARC AR-15s, and Next Level states it also works with 6.5 Grendel. It shares the NLX556 DLC group's build: a 4140ph carrier with an expanded rear, an SAE 4140ph bolt that is shot peened and MPI inspected, a machined extractor with insert and O-ring, and hardened Grade 8 gas key screws torqued and staked.
Every part is DLC coated for low friction and fast cleanup. Next Level pairs it with the Helix 6 carbon fiber barrel in its Phoenix 6ARC rifles. Its page does not state a bolt face type, so confirm against the barrel maker's requirement.
