Luth-AR® A2 Stripped AR-15 Upper Receiver – Precision 7075-T6 Aluminum Forging – Integrated Classic Carry Handle – Matte Black Hardcoat Anodized with Teflon Coating – UR-A2-S
Product Description
The Luth-AR® A2 Stripped AR-15 Upper Receiver (UR-A2-S) represents a premier mechanical benchmark in retro-inspired rifle design, legacy clone building, and structural receiver logistics, masterfully engineered in the USA. Purpose-built to serve as the absolute foundation for authentic M16A2-style carbine or rifle builds, this component revives timeless military design with modern manufacturing precision. While traditional modern flattop upper receivers require heavy bolt-on optics risers and modular rear sight blocks that break up the weapon's clean lines, the A2 profile incorporates an integrated fixed carry handle structure. This premium forged asset (812058030751) establishes an indispensable foundation for military collectors, classic rifle cloning enthusiasts, and custom firearm builders looking to execute a zero-fail retro staging layout.
The core structural backbone of this stripped upper receiver is precision-machined from a premium, high-grade 7075-T6 aircraft aluminum forging. To safeguard the structural housing against severe wear, dynamic environmental moisture, and abrasive carbon fouling, the metal is completed with a deep **Mil-Spec Type III hardcoat anodized finish backed by an ultra-tough, scratch-resistant Teflon™ layer**. This advanced surface treatment provides an incredibly slick surface that coordinates perfectly with standard mil-spec charging handles and bolt carrier group rails, facilitating friction-free cycling action. The chassis arrives natively with pre-milled cuts to accommodate standard **windage and elevation adjustable A2 rear sight components**, alongside an integrated shell deflector and a dedicated forward assist housing.
The true operational triumph of this American-built masterpiece lies in its strict adherence to traditional structural dimensions. Outfitted with an **unramped, classic A2-style profile (Does NOT feature M4 style feed ramps)**, this upper matches flawlessly with standard rifle-extension barrel configurations. The receiver accepts any standard mil-spec ejection port cover pin assembly and round forward assist package, granting builders the freedom to source their favorite custom or authentic small parts arrays. Weighing a minimalist 0.60 pounds (9.60 ounces) in its bare form, this A2 component yields total mechanical and structural authority over your custom retro build loop.
Includes: (1) Authentic Luth-AR Stripped A2 Upper Receiver Core (Matte Black Hardcoat Anodized Forged 7075-T6 Shroud, Integrated Carry Handle, Machined A2 Rear Sight Channel Cuts, Shell Deflector, Forward Assist and Dust Cover Housing), Packed in Original Branded Factory Sealed Protection Packaging.
*Administrative Staging, Assembly & Compatibility Guidance: The Luth-AR UR-A2-S is an authentic stripped asset; it **does NOT include the A2 rear sight assembly hardware, forward assist plunger, or ejection port door assembly**, which must be sourced independently. Because this receiver features a traditional unramped feed throat entry path, it is precisely optimized to pair with standard **rifle-extension barrels**; using a barrel with an M4-style extension is technically physical but requires vigilant headspace and feeding verification to prevent failure-to-feed anomalies. Always utilize dedicated upper receiver vice blocks and a calibrated torque wrench when tightening your barrel nut to prevent structural twisting. Ensure your workspace is entirely clear of live ammunition before staging component mock-ups on your bench.
