FREE CMMG Gunbuilder's Lower Parts Kit with BRN-15 Lower Receiver
Get a FREE CMMG AR-15 Gunbuilder's Lower Parts Kit with the purchase of a Brownells BRN-15 Forged Stripped Lower Receiver. This combo gives you a quality forged AR-15 lower and the essential small parts needed for your build, while leaving you free to select your preferred trigger, pistol grip and trigger guard.
Brownells BRN-15 Forged Stripped Lower Receiver
The Brownells BRN-15 lower receiver is precision-machined from a 7075-T6 aluminum forging to standard mil-spec AR-15 dimensions for compatibility with commonly available lower receiver components. Its matte black Type III hardcoat anodized finish provides a durable, wear-resistant surface.
Supplied stripped, the BRN-15 provides a straightforward starting point for a custom AR-15 build.
FREE CMMG AR-15 Gunbuilder's Lower Parts Kit
The included CMMG Gunbuilder's Kit provides the pins, springs, detents and other small components needed for a standard AR-15 lower receiver assembly. Rather than including a basic trigger, grip and trigger guard that you may ultimately replace, this kit leaves those selections up to you.
It's a practical complement to the BRN-15 stripped lower, and with the Gunbuilder's Kit included at no additional cost, you can put more of your build budget toward the components you actually want.
