Andro Corp URS AR-15 FORGED UPPER RECEIVER 7075 - URS - 736684139674
Product Description
Building or retrofitting a high-performance AR-15 rifle requires a structurally sound upper receiver shell that ensures precise barrel extension seating and proper alignment for the bolt carrier group. Out-of-spec stripped uppers can introduce severe cycling drag, canted optics rails, or bullet-nose catching against improperly cut feed ramps. The Andro Corp Industries URS AR-15 Forged Upper Receiver (URS) eliminates these structural and alignment vulnerabilities by providing a precision-machined, Mil-Spec forged 7075-T6 aluminum foundation built for hard tactical use.
Forged from ultra-durable 7075-T6 aircraft-grade aluminum, the URS stripped upper receiver is treated with a Type III Class 2 hardcoat anodized matte black protective finish that guards against surface abrasion, chemical solvents, and harsh environmental wear. Precision-machined M4 feed ramps guide cartridges smoothly from magazine to chamber, preventing nose deformation and loading jams during rapid semi-automatic or full-auto firing schedules.
Engineered to standard Mil-Spec dimensions, the URS features a full-length flat-top Picatinny rail for optics and sight mounting, as well as factory-drilled ports for standard forward assist and ejection port dust cover hardware. Whether completing a custom build or staging a spare upper shell for caliber conversions, the Andro Corp URS upper receiver delivers duty-grade strength and flawless component compatibility.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment & Component Matrix: Direct compatibility with standard Mil-Spec AR-15 lower receivers (0.250" takedown/pivot pin holes), standard AR-15 charging handles, bolt carrier groups, and barrels with M4 feed ramp extensions. Note: Stripped upper shell format; forward assist assembly and ejection port dust cover are sold separately.
Installation & Assembly Sequence:
- Safety check the workspace and clean all internal upper threads and sockets.
- Install the ejection port cover assembly and forward assist kit into the receiver body using standard armorer roll pin punches.
- Apply a liberal coat of aerosol grease (AeroShell 64 / 33MS) to the external barrel nut threads of the upper receiver.
- Insert your barrel extension into the receiver socket, ensuring the indexing pin aligns smoothly with the top alignment notch.
- Thread on the barrel nut and torque using an armorer's wrench to manufacturer specs (typically 30–80 ft-lbs). Install the gas system, handguard, bolt carrier group, and charging handle to perform dry-fire cycling checks.
