Spike's Tactical Generation 2 Billet Upper Receiver – .223/5.56 – SFT52B2
The Spike's Tactical Gen II Billet Upper (810083267760) is a 2026-spec premium receiver that moves beyond mere aesthetics to offer genuine functional upgrades for the AR-15 platform. Machined from a solid block of 7075-T6 billet aluminum, the Gen II has been updated with internal pocketing to reduce weight to just 10.4 oz without sacrificing the structural rigidity billet is known for. Unlike standard uppers, Spike's flared the side walls to prevent accidental bolt release and enlarged the bolt catch cutout area, making this one of the few billet uppers fully compatible with the Magpul BAD Lever and other oversized aftermarket bolt releases.
Every SFT52B2 undergoes a rigorous manufacturing process where M4 feed ramps are cut before the Type III Hardcoat Anodizing to ensure maximum feeding reliability and surface protection. The Gen II also features a unique set-screw attachment for the forward assist instead of a traditional roll pin, making maintenance significantly easier. Designed to work with standard Mil-Spec barrel nuts and most aftermarket rail systems, this receiver features laser-engraved T-marks and the iconic Spike's Spider logo. Whether you are building a high-speed competition rig or a precision "Recce" rifle, the Spike's Gen 2 Billet Upper provides a rock-solid, precisely machined foundation that stands out in both form and function.
Includes: (1) Spike's Tactical Gen II Billet Upper Receiver, Forward Assist (Installed), and Ejection Port Door Assembly (Installed).
