About this product

```html Wilson Combat Mil-Spec AR-15 Carbine Buffer Tube Kit: Precision Fit for Reliable Cycling Upgrade your AR-15’s recoil system with the Wilson Combat Mil-Spec Carbine Buffer Tube Kit, engineered for consistent performance in carbine-length gas systems. Machined to strict mil-spec dimensions, this buffer tube ensures compatibility with standard stocks while reducing play for tighter lockup. Whether you're building a lightweight patrol rifle or retrofitting an existing setup, this kit delivers the durability and fit expected from Wilson Combat’s legacy of precision manufacturing. Ships fully assembled with all necessary components for drop-in installation. Key Specifications Material: 7075-T6 aluminum buffer tube (Type III hardcoat anodized) Compatibility: Mil-spec carbine stocks (commercial tubes not supported) Includes: Buffer spring, carbine-weight buffer (3.0 oz), castle nut, end plate Finish: Matte black corrosion-resistant coating Weight: 7.8 oz (complete kit) Built for Duty-Grade Reliability The heart of this kit is the 7075-T6 aluminum buffer tube, a step above common 6061 alloys for its superior tensile strength. Wilson Combat’s machining process holds tight tolerances to prevent stock wobble, a critical factor for maintaining cheek weld consistency during rapid fire. The anodized finish resists wear from adjustable stock adjustments, even under frequent positional changes. Included components are matched to work as a system—the carbine buffer weight is optimized for mid-length and carbine gas systems, reducing bolt carrier group (BCG) velocity without over-damping. The spring uses a uniform pitch design to minimize harmonic distortion that can contribute to inconsistent cycling in high-round-count sessions. Installation requires no specialized tools beyond an armorer’s wrench for the castle nut. The end plate features positive indexing for anti-rotation tabs found on many sling mounts, while the castle nut’s staked notches provide visual confirmation of
