Bushmaster QRC II — 5.56x45mm NATO, 10+1, 16" Barrel, Black, Collapsible Carbine Stock, A2 Grip, 14" M-LOK® Handguard (Model 1010017BLK | UPC 604206201690)

Ready for your optic and ready for work, the Bushmaster QRC II (Quick Response Carbine) is a modern AR-15 built to deliver reliability, control, and upgrade flexibility from day one. Chambered in 5.56x45mm NATO with a versatile 16-inch barrel and a slim 14" free-float M-LOK® handguard, this optics-ready carbine balances maneuverability with real accuracy potential. A classic A2 grip and collapsible carbine stock keep the setup familiar and duty-simple, while the continuous top rail makes mounting a red dot, LPVO, or irons straightforward.

Why the QRC II Belongs in Your Rack

• Optics-Ready Upper: Flat-top receiver with uninterrupted Picatinny rail for easy mounting of red dots, magnifiers, or LPVOs—no fixed front sight tower to work around.

• 16" Do-Everything Barrel: The sweet spot for general purpose carbine use—maintains useful velocity for defensive and training loads while staying handy in vehicles and structures.

• 14" Free-Float M-LOK® Handguard: Preserves barrel harmonics for tighter groups and provides generous space for white lights, sling QD cups, hand stops, and bipods without adding bulk.

• Familiar Controls & Furniture: Collapsible carbine stock adjusts for body armor or seasonal layers; A2 grip offers proven, no-nonsense ergonomics.

• 10+1 Capacity: Ships with a 10-round magazine—ideal for restricted jurisdictions or shooters who prefer low-profile mags for bench and prone work.

Real-World Advantages

• Consistent Accuracy: Free-floating the barrel reduces point-of-impact shifts when loading a bipod or bracing on barricades.

• Modern Handling: The long, slim rail supports a forward support-hand grip, better recoil tracking, and clean cable management.

• Upgrade-Friendly: From triggers and stocks to muzzle devices and sling mounts, the platform is ready to evolve with your skills and needs.

Ideal Use Cases

• Training & Classes: Reliable, optics-ready carbine that takes to accessories easily and holds zero through heavy round counts.

• Ranch/Property Carbine: Lightweight, maneuverable, and quick to stage with a sling and light.

• Range & Home Defense (where lawful): Configure with your preferred optic and white light for confidence day or night.

Pro Setup Tips

1. Optics Choice: Pair with a 1–6x/1–8x LPVO for versatility or a micro red dot + 3x magnifier for speed and reach.

2. Zero Strategy: Common picks are 50/200-yard or 100-yard zeros; always verify cold-bore POI.

3. Sling & Light: Two-point sling with QD placements at the handguard and receiver; mount a 1,000-lumen class light at the 10–11 or 1–2 o’clock for thumb access.

4. Maintenance: Keep the bolt carrier group lightly lubricated, especially during break-in; re-torque M-LOK® accessories after the first 100–200 rounds.
