DPMS Panther Arms 5.56/300 Blackout Phosphate Steel Bolt Carrier Group

Upgrade your AR-15 with the DPMS Panther Arms Bolt Carrier Group, engineered to deliver reliable, mil-spec performance for both 5.56 NATO and 300 Blackout calibers. Built to the exacting standards that serious shooters demand, this BCG features a bolt machined from Carpenter 158 steel — the same material specification used in military-grade components — then shot peened and high-pressure tested for maximum durability and safety. Every bolt also undergoes magnetic particle inspection to ensure structural integrity before it leaves the factory.

The gas key is precision-machined from bar stock, chrome lined, phosphate coated, and secured with Grade 8 fasteners staked to mil-spec standards — eliminating the risk of loosening under sustained fire. The bolt carrier itself is phosphate coated on the exterior for corrosion resistance and chrome lined on the interior for smooth cycling and easy cleaning.

Note: For packaging and storage considerations, this BCG ships dry and may appear grey or dusty upon arrival. This is completely normal — simply apply your preferred CLP or lubricant and it will return to its characteristic black finish and be ready for action.

Whether you’re building a new rifle, replacing a worn component, or upgrading your current setup, the DPMS Panther Arms BCG delivers proven mil-spec reliability at a competitive price.
