What’s Included
- Lead Star GRUNT-15 AR pistol
- 1 × 30-round Mission First Tactical polymer windowed AR-15 magazine
Built on the proven AR-15 direct-impingement platform, the GRUNT-15 uses 7075-T6 hard-coat anodized receivers with an integral enlarged trigger guard for gloved use. An uninterrupted top rail runs from the receiver through the free-float handguard, allowing flexible optic and accessory placement.
The 10.5" 4150 CMV steel barrel is nitride treated for corrosion resistance and threaded 1/2-28. A square-profile linear compensator is installed, directing blast downrange while preserving overall compactness.
Lead Star’s slim GRUNT M-LOK aluminum handguard keeps weight down and leaves all clock positions open for accessories. Standard rail segments and QD sockets are ready for lights, grips, or slings without adding bulk.
An extended star-logo charging handle latch speeds manipulation, while a standard magazine release and multi-caliber marked lower keep controls familiar. The adjustable black polymer brace aids stability without sacrificing maneuverability in tight spaces.
Packing full-size capability into a small footprint, the GRUNT-15 offers an MSRP of $799, making it an appealing choice for shooters who want Lead Star quality in a ready-to-run format.
