One Horse LLC 7 Inch M LOK Free Float AR 15 Handguard Black OHHG03 UPC 850078799203
Product Description
The One Horse LLC® 7" M-LOK Free Float AR-15 Handguard (SKU: OHHG03 / UPC: 850078799203) is an agile, ultra-compact tactical forend purpose-built for AR pistol builds, Short Barreled Rifles (SBRs), and sub-carbine defensive platforms. By isolating the barrel assembly from external handling pressure, rest contact, and sling tension, this free-float rail preserves barrel harmonics and prevents point-of-impact (POI) deviation. Featuring an uninterrupted Mil-Spec 1913 Picatinny top rail paired with direct-attachment M-LOK modularity along the 3, 6, and 9 o'clock axes, it delivers essential tactical modularity in a maneuverable, tight-quarters footprint.
Precision CNC-machined from extruded 6061-T6 aerospace-grade aluminum alloy, the OHHG03 forend is treated with a non-reflective MIL-A-8625 Type III Class 2 hardcoat anodize. This deep matte black military-grade finish establishes a rugged protective boundary against surface scratching, field abrasion, harsh chemical bore cleaners, and high-heat cycles encountered during sustained firing drills. The system anchors via a heavy-duty alloy steel barrel nut designed for standard 1.250"-18 TPI upper receiver threads, delivering dependable structural rigidity and zero-flex alignment without requiring complicated shims or gas-tube timing routines.
Engineered with a streamlined outer profile, the One Horse 7" M-LOK rail enhances dexterity for modern support-hand control, thumb-over-bore C-clamp shooting stances, and rapid target transitions. The slim interior diameter cleanly clears standard .750" low-profile gas blocks while keeping bulk and front-end mass to an absolute minimum. Dual clamp-on lower cross-bolts securely lock the handguard chassis to the steel barrel nut, delivering dependable retention and optic/laser zero-holding stability under aggressive operational handling.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct fit for Mil-Spec AR-15 / M4 forged and billet upper receivers. Optimally paired with 7.5", 8.0", and 8.5" barrel lengths running pistol-length gas blocks, or extended barrels running low-profile micro gas blocks. CRITICAL: Incompatible with AR-10 / DPMS LR-308 / Armalite large-frame platforms. Internal diameter does NOT accommodate tucked standard suppressors. Barrel nut installs using a standard armorer wrench or crowfoot flat; torque to 35-45 ft-lbs using Aeroshell 33MS or Mil-Spec moly grease. Apply medium blue threadlocker to clamp bolts and torque to 35-40 in-lbs.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Secure the stripped upper receiver into an armorer reaction rod or rigid receiver vise block; clean receiver threads and apply a uniform coat of Aeroshell 33MS grease.
- Thread the included steel barrel nut onto the receiver and torque to 35-45 ft-lbs using an armorer wrench; verify gas tube pathway clearance through the receiver.
- Slide the One Horse handguard over the barrel and onto the steel barrel nut, aligning the top 1913 Picatinny rail seamlessly flush with the upper receiver flat-top rail.
- Install the dual lower clamp cross-bolts, apply medium-strength blue threadlocker, torque evenly to 35-40 in-lbs, and conduct a full mechanical clearance and function check.
