Real-World Applications

Lights & lasers at the perfect clock position

Place a 1913-base light or laser exactly at 3/6/9 o’clock to match your grip and switch ergonomics. The 9-slot run makes it easy to clear front sights, sling cups and cable guides while keeping your thumb-over-bore index natural.

Stability & control upgrades

Mount a vertical or angled foregrip where it best balances the carbine, or add a bipod further out for prone stability without re-railing the entire forend.

Modular, mission-driven layouts

Run your handguard slick and bolt on rail only where you need accessory capability. Remove it when shaving ounces for long hunts or fast PCC stages.

Mechanical & Build Highlights

• 6063-T6 aluminum body: Balanced strength-to-weight with good corrosion resistance for field use. :contentReference[oaicite:5]{index=5}
• Low-profile geometry: Keeps the support-hand grip comfortable and minimizes snag points.
