Brownells 75th Anniversary - A Shooting Heritage

Flavors Your .308 With a Bit of Old-School Flavor, Plus The Convenience of Modern Parts Compatibility

The 308 Bolt Carrier Group from Brownells is styled to replicate the BCG on Eugene Stoner’s original ArmaLite® AR-10® rifle of the late 1950s - the original AR-pattern rifle. And while it is compatible with any DPMS pattern 308 upper receiver it’s also an ideal component to add an extra level of period detail and authenticity to a "retro" rifle build - especially if you’re using the Brownells BRN-10 upper receiver.

The 308 Bolt Carrier Group has angled flat sides and two enlarged flanges on the tail for flawless travel inside the receiver extension. A hard-chromed finish on the BRN-10 provides excellent resistance to surface wear, plus smooth operating lubricity, while adding an extra bit of period-correct detail.

  • Hard chromed carrier, gas key, cam pin, extractor & bolt
  • 8620 tool steel carrier
  • 9310 magnetic particle inspected bolt
  • Gas key screws are torqued & staked

Brownell’s 308 Bolt Carrier Group is compatible with DPMS LR-308 upper receivers and components, as well as DPMS clones. It will give a distinctive look to your next custom AR-style .308 rifle build, yet is fully compatible with modern DPMS-pattern receivers, buffers, charging handles and barrels.
