TACFIRE BU-308-7 308 PSTL UPPER 7 W/BCG - SKU: BU-308-7 - UPC: 729205708985
Product Description
The Tacfire BU-308-7 is a complete short-barreled upper receiver assembly engineered specifically for DPMS-pattern .308 Win / 7.62x51mm NATO AR-10 pistol and SBR builds. Built around a compact 7-inch heavy contour barrel, this complete upper delivers explosive rifle-caliber firepower in an extremely compact, ultra-maneuverable package designed for close-quarters engagements, compact truck-gun staging, and range performance.
Forged from high-strength 7075-T6 aircraft-grade aluminum and finished in a matte black hardcoat anodization, the receiver interfaces cleanly with standard DPMS-pattern lower receivers. The assembly features a free-float M-LOK handguard that provides full-length top Picatinny rail space for optics alongside modular attachment slots for tactical lights, grips, and indexing accessories. The 7-inch barrel is tipped with a heavy-duty muzzle brake to mitigate aggressive recoil and muzzle climb associated with short-barrel .308 Winchester discharges.
Delivered completely assembled and ready for drop-in coupling, the BU-308-7 includes a full-auto profile .308 Bolt Carrier Group (BCG) and a standard charging handle, ensuring complete out-of-the-box staging reliability.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Designed for DPMS-pattern Gen 1 AR-10 / .308 lower receiver platforms. (NFA Warning: Coupling a barrel under 16 inches to a lower receiver with a shoulder stock creates a Short-Barreled Rifle [SBR] subject to NFA regulation—verify receiver classification prior to assembly).
- Verify host lower receiver is completely clear, magazine removed, and chamber confirmed empty.
- Apply a generous coating of quality firearm lubricant to the four BCG carrier glide rails, bolt cam pin, and locking lugs.
- Insert the provided charging handle and BCG into the upper receiver cavity until fully locked forward into the barrel extension.
- Align upper receiver pivot and takedown pin holes with the host lower receiver and push pins fully home to secure the lockup.
- Conduct manual charging handle cycling checks to confirm smooth lockup, positive extraction, and complete forward bolt seating.
