Wilson Combat M-LOK Rail — 12.60" | 6005A-T5 Aluminum | Black Hard-Coat Anodized | Model TRMLOK12 | UPC: 811826026873
Upgrade your AR-15 platform with the Wilson Combat TRMLOK12 — a precision-machined, free-float M-LOK handguard engineered for repeatable accuracy, lightweight feel, and battlefield-grade durability. Built from aerospace-grade 6005A-T5 aluminum and finished in a hard-wearing black hard-coat anodize, the 12.60" TRMLOK12 delivers the ideal balance of rail real estate and maneuverability for hunters, competitors, and tactical operators who demand the best from their rifle.
Premium Materials & Precision Machining
Wilson Combat mills the TRMLOK12 from 6005A-T5 aluminum, offering an exceptional strength-to-weight ratio and superior stiffness where it matters. CNC machining to tight tolerances ensures concentricity and repeatable alignment with your upper receiver — an essential factor for accuracy and accessory zero retention.
Material: 6005A-T5 aircraft-grade aluminum
Finish: Black hard-coat anodized for corrosion resistance, surface hardness, and low reflectivity
Manufacturing: Precision CNC machining for consistent fit and long service life
Free-Float Design for Improved Accuracy
The TRMLOK12 is a true free-float handguard, isolating the barrel from handguard contact and accessory pressure. That isolation reduces inconsistent barrel harmonics and helps tighten group sizes, especially on precision and long-range AR-15 builds.
Free-float configuration improves barrel harmonics and shot-to-shot consistency
Stable mounting surface for optics, lights, bipods, and rails
M-LOK Modular Attachment System
Equipped with direct M-LOK® slots along the full length, the TRMLOK12 gives you modern, low-profile modularity. Mount rail sections, QD sling mounts, lights, vertical grips, hand stops, and other accessories only where you need them — keeping the handguard slim and ergonomic.
Engineered for Lightweight Strength & Ergonomics
Wilson Combat optimized the TRMLOK12’s profile to reduce weight while maintaining a rigid backbone. The slim outer diameter provides a natural, positive grip and excellent cheek weld, improving natural pointability and control under stress.
Rock-Solid Finish That Stands Up to Use
The black hard-coat anodize provides a tactical, non-reflective appearance and protects the handguard from scratches, corrosion, and abrasion. It’s designed to hold up in adverse environments — from wet field conditions to heavy training schedules.

Installation Overview (High Level)
The TRMLOK12 is designed for experienced builders and qualified gunsmiths. Typical install steps include: remove the existing handguard, install the recommended barrel nut, align the TRMLOK12 to the upper receiver, secure per Wilson Combat torque specs, then mount accessories and verify fit/function. Because AR-15 interfaces vary, follow Wilson Combat’s installation instructions or consult a professional gunsmith to ensure correct torque, alignment, and headspace.
Ideal Applications
Precision Builds & Long-Range: Free-float rigidity and long rail length support stable optics and bipods for accuracy.
Competition: Extended M-LOK real estate for staging lights, laser, and support gear without excessive bulk.
Hunting: Lightweight, ergonomic, and durable for backcountry carry and fast shouldering.
Duty / Patrol: Hard-coat anodize and modularity make it a rugged platform for mission equipment.
