TacFire AR-15 Forged 7075-T6 Aluminum Stripped Upper Receiver Kit with Charging Handle, Forward Assist, and Ejection Port Dust Cover UP01-C2
Product Description
When engineering or assembling custom AR-15 rifle configurations, armorers and tactical builders frequently encounter an acute operational bottleneck of structural component procurement lag and part-to-part mismatch errors when sourcing critical upper completion hardware from scattered, non-standardized suppliers. Minor variances in pivot pin hole metrics, spring rates, or component tolerances across detached brands can introduce unwanted frame-to-hardware loose play, culminating in sticky forward assist buttons, rough charging handles, or misaligned dust cover detents. The TacFire AR-15 Stripped Upper Receiver Combo Kit completely bypasses these stacking tolerance liabilities, packaging a premium, mil-spec flat-top upper with a dimensionally verified collection of core completion hardware.
The structural foundation of this versatile assembly is precision CNC-machined from a monolithic, ultra-dense 7075-T6 aircraft-grade aluminum alloy forging, yielding massive shear resistance and an exceptional operational lifespan under heavy reciprocating gas pressures. Following rigorous milling sequences to guarantee exact military dimensional baselines, the chassis is treated with a non-reflective, Mil-Spec Type III hardcoat black anodized finish to defend against deep scratching, aggressive field manipulation, and environmental moisture. The internal cylinder pathway is mapped to tight tolerances, ensuring smooth, friction-free tracking of standard bolt carrier groups across prolonged strings of fire.
Executing an optimized, direct-interfacing installation geometry, this upper receiver incorporates precision-cut M4-style feedramps calibrated to blend flawlessly with standard barrel extensions, entirely overriding cartridge nose-diving or feeding stutter. The top face is crowned with a continuous MIL-STD 1913 Picatinny rail field that accepts tactical optics, iron sights, and magnifiers with zero-drift mounting stability under intense recoil vibrations. Arriving in a clean, unassembled layout to allow personalized tuning, the kit ships fully equipped with a robust mil-spec charging handle, a forward assist assembly with a hardened steel pawl, and a complete spring-loaded ejection port dust door array to permanently isolate your rifle's action from extreme field dirt and debris.
Each individual factory retail package contains one TacFire black anodized forged stripped upper receiver, one mil-spec aluminum charging handle, one forward assist assembly (with roll pin and spring), and one complete ejection port cover assembly (with rod and spring).
*Administrative Armorer Staging, Upper Assembly Guidance: This comprehensive standard-frame component group (Part # UP01-C2) is strictly dimensioned for standard AR-15 lower receivers and is highly optimized to run intermediate centerfire calibers like 5.56x45mm NATO, .223 Remington, .300 AAC Blackout, 6.5 Grendel, and 7.62x39mm. Armorers must note that this kit is delivered in an unassembled, loose component staging layout, requiring standard bench blocks, a roll-pin punch set, and pivot-pin detailing tools to fully complete the hardware integration tracks. During workbench assembly loops, ensure the dust cover spring is wound under adequate reverse tension before seating the retaining rod, and verify that the forward assist roll pin is driven flush to prevent manual interference with charging handle travel. Always apply a drop of synthetic machine oil to the charging handle operational tracks during final staging to preserve clean performance boundaries.
