Wilson Combat AR-15 Stripped Billet Lower Receiver

Precision starts here. The Wilson Combat AR-15 Stripped Billet Lower Receiver is machined from 7075-T6 aluminum for uncompromising durability, with a Type III hardcoat anodized finish that withstands harsh conditions. Designed for builders who demand tight tolerances and a solid foundation, it accepts most mil-spec parts without modification. Ships ready for your custom build—no FFL required for purchase (check local laws).

Key Specifications

• Material: 7075-T6 aerospace-grade aluminum billet
• Finish: Type III hardcoat anodized (matte black)
• Compatibility: Fits standard AR-15 upper receivers & mil-spec parts kits
• Weight: 8.5 oz (unassembled)
• Trigger Pocket: Machined for crisp break with aftermarket triggers
• Threading: 1/4″-28 takedown pin detent, 4-40 grip screw

Feature Breakdown

The receiver’s billet construction eliminates weak points found in forged lowers, with reinforced pivot/takedown pin areas to prevent wallowing under heavy use. Machining marks are hand-deburred for smooth operation, and the magazine well is beveled for faster reloads. Tighter-than-standard tolerances reduce play between upper and lower receivers when paired with quality components.

Wilson Combat’s anodizing process exceeds MIL-A-8625 standards, providing corrosion resistance without adding thickness that could interfere with pin fitment. The fire control pocket is precision-cut to minimize trigger creep, especially beneficial for match or tactical triggers. All critical surfaces are stress-relieved post-machining to maintain dimensional stability.

Unlike budget lowers, this model includes a threaded bolt catch roll pin hole (4-40) for easier installation. The safety selector detent channel is radiused to prevent binding, while the buffer tube threads are chased to ensure proper alignment with carbine or rifle stocks. Flared trigger guard accommodates gloved use without sharp edges.

Each receiver is serialized per ATF requirements and includes a tensioning screw to adjust upper/lower fit. The minimalist logo engraving maintains a professional appearance for duty or competition builds. No extra milling or fitting is needed for drop-in triggers or ambidextrous controls.

Compatibility Notes

Works with:

• Mil-spec AR-15 upper receivers (check for M4 feed ramps if building 5.56mm)
• Commercial buffer tubes (carbine or rifle length)
• Most aftermarket triggers, including cassette-style designs

Does not support:

• AR-10/.308 platforms
• Proprietary lowers requiring special uppers

Installation Overview

Assemble using standard AR-15 tools: pivot pin installation tool, roll pin punches, and armorer’s wrench for buffer tube. Lower parts kits may require minor fitting of safety selectors—lightly polish contact points if needed. The threaded bolt catch roll pin accepts a 4-40 set screw (included) for tool-free installation. Apply grease to takedown pin detents during assembly to prevent wear.

FAQ

Q: Is this a complete lower receiver?
A: No, this is a stripped lower—you’ll need a parts kit, buffer system, and stock to complete assembly.

Q: Does it include a magazine?
A: Magazines are sold separately to comply with state restrictions.

Q: Can I use this for a pistol build?
A: Yes, if configured with a pistol brace and sub-16″ barrel (consult ATF guidelines).

Q: Are jigs available for engraving?
A: We recommend professional laser engraving due to the hardened anodizing.

Q: What’s the lead time for shipping?
A: Orders ship within 2 business days via tracked carrier (excluding weekends/holidays).
