BCM MK2 Upper Receiver Details
BCM builds these uppers from 7075-T6 aluminum, known for its high strength-to-weight ratio. The forging process maintains grain structure for enhanced durability – something you appreciate when you’re putting rounds downrange during a Montana hunting season, or putting in time at the range. The MK2 is designed to work with standard AR components, meaning you won’t have issues with bolt carriers, charging handles, or barrel assemblies.
- Platform: AR-15/M4
- Material: 7075-T6 Aluminum
- Finish: Black Hard Coat Anodized
- Sights: Optic Ready (No Iron Sights)
- Series: MK2
- Engraving: Laser Engraved
This upper receiver is stripped – it does *not* include a forward assist, ejection port cover, or sights. It’s a bare receiver, giving you the flexibility to customize with the components you prefer. It’s a good starting point for a custom build.
Whether you’re building a rifle for deer hunting in the backcountry, setting up a home defense gun, or just enjoy target shooting, the BCM MK2 is a solid foundation.
