Vltor 5 Position Receiver Extension

The VLTOR 5 Position Receiver Extension (RE-1) is a mil-spec carbine receiver extension tube engineered for precision and durability in demanding operational environments. Built from 7075-T6 impact extrusion material and finished with mil-spec hardcoat anodization per MIL-A-8625 Type III, Class 2, this tube delivers the material strength and corrosion resistance required for extended field duty. The five indexed stock positions—each marked with numerals laser-etched on the top surface—enable rapid visual confirmation without removing your cheek from the stock, a critical advantage during tactical transitions or low-light operations.

The precision-machined internal bore ensures smooth, consistent operation of buffer components across the full range of positions, eliminating binding or friction that can degrade reliability under sustained fire. The hardcoat anodized finish resists corrosion in salt-air environments, high-humidity climates, and after extended water immersion—critical for operators working in coastal zones, swamp terrain, or amphibious operations. At 0.31 lbs and measuring 7.5 inches in length, the RE-1 integrates seamlessly into carbine platforms without adding undue weight or length to your rear assembly.

This receiver extension tube is purpose-built for operators, law enforcement, and serious rifle builders who require mil-spec compliance, rapid index confirmation, and proven material performance. Whether you're building a patrol carbine, upgrading an existing platform, or consolidating gear for training and qualification, the VLTOR RE-1 receiver extension delivers the precision and durability expected from professional-grade components. The five-position design accommodates different shooter body armor configurations, body types, and firing positions—from close-quarters work to standoff ranges.
