Compact Platform Design

This kit prioritizes maneuverability without sacrificing reliability. The 7.5-inch barrel length combined with the pistol-length gas system creates a platform that's easy to handle in vehicles, tight spaces, or dynamic scenarios. The stainless steel construction resists corrosion, making this a durable choice for long-term use. The micro low-profile gas block keeps the top rail clear for optic mounting while maintaining proper cycling reliability.

SBA3 Brace Configuration

The SBA3 adjustable brace ships with the kit and provides multiple position options to suit different shooting styles and body types. The design allows for consistent cheek weld and stable control during firing. The brace integrates seamlessly with the mil-spec buffer tube included in this kit, creating a complete rear assembly without additional parts needed.

M-LOK Handguard Ecosystem

The 7-inch M-LOK handguard supports the modern accessory ecosystem, allowing you to attach lights, vertical grips, sling mounts, and other tactical components. The freefloat design ensures the barrel remains isolated from handguard pressure, supporting accuracy consistency. The length balances coverage and maneuverability, leaving the muzzle device visible for flash hider function.

Complete Component Quality

Every component meets mil-spec standards. The bolt carrier group uses 9310 alloy steel with nitride finish for wear resistance. The lower parts kit includes all internal components required for reliable operation. The buffer, recoil spring, castle nut, and end plate are all mil-spec quality, ensuring consistent performance across the build.
