Product description
NiB-X BCG and Matching Hammer in One AR-15 Upgrade Package
Features
- Complete AR-15/M16 bolt carrier group supplied with a matching NiB-X coated hammer
- Standard .223/5.56 bolt face is also compatible with .300 Blackout
- M16-profile carrier uses an extended lower shroud and works in compatible semi-automatic AR-15 rifles
- 8620 steel carrier provides durable construction for the reciprocating assembly
- Carpenter 158 steel bolt provides proven material strength at the locking lugs and bolt face
- WMD NiB-X nickel boron coating provides a hard, low-friction surface that reduces fouling adhesion and simplifies cleaning
- Extractor uses a black buffer, spring, and O-ring for positive extraction
- NiB-X coating is backed by WMD against chipping, flaking, spalling, and thinning
The WMD Guns NiB-X Bolt Carrier Group and Hammer package combines the primary AR-15 operating assembly with a matching coated fire-control component. NiB-X is applied to provide slick metal-on-metal contact, reduce carbon adhesion, and make routine maintenance easier, with the included hammer extending those coating benefits into the lower receiver. The standard .223/5.56 bolt face also makes the BCG suitable for compatible .300 Blackout configurations.
Note: The included hammer is intended for compatible AR-15 fire-control systems. Verify compatibility before pairing it with proprietary aftermarket or two-stage trigger assemblies.
