Optics-Ready 5.56 NATO AR Built for Lightweight Performance
Chambered in 5.56x45mm NATO (.223 Rem), the Bushmaster QRC II Pro gives you the versatility to run a wide range of ammo while staying compatible with the most common AR-15 magazines and accessories.
Key performance features include:
16" 4150 CMV pencil barrel – heat-treated, chrome-moly vanadium steel for strength and longevity.
Salt bath nitride finish – adds corrosion resistance and surface hardness without the weight of traditional chrome lining.
1:7" twist rate – stabilizes a wide range of heavier 5.56 projectiles commonly used for accuracy and longer-range shooting.
1/2x28 threaded muzzle with A2 flash hider, giving you the option to swap in a suppressor or muzzle brake if desired.
At around 5.8–5.9 lbs unloaded and an adjustable overall length of roughly 33"–36.5", the QRC II Pro is configured to be fast, maneuverable, and easy to carry all day.
14" Free-Float M-LOK Handguard – Maximum Control & Modularity
The 14" M-LOK free-float handguard anchors the QRC II Pro firmly in the modern AR era:
Free-float design – removes pressure points from the barrel for more consistent accuracy, especially with supported or bipod shooting.
M-LOK slots along multiple sides – let you mount lights, grips, bipods, QD sling cups, and other mission-specific accessories exactly where you want them.
Slim, ergonomic profile – helps you maintain a solid support-hand grip and control the rifle during rapid strings of fire.
Paired with the pencil-profile barrel, this extended handguard gives you excellent reach and control without making the rifle front-heavy.
Forged 7075-T6 Receivers & Mil-Spec Reliability
Bushmaster builds the QRC II Pro on forged 7075-T6 aluminum upper and lower receivers, the industry standard for duty-grade ARs:
Forged 7075-T6 – stronger and more impact-resistant than many cast or lower-grade alternatives.
Hard-anodized finish – protects against wear, impacts, and environmental exposure.
Mil-spec trigger – a rugged, consistent single-stage trigger tuned for reliability under real-world conditions.
Salt bath nitride / MPI-tested bolt carrier group – engineered for long service life and dependable cycling.
Together with a carbine-length gas system, this setup is tuned for dependable operation with a wide variety of ammunition while keeping recoil impulse manageable and smooth.
Premium B5 Systems Furniture – Bravo Stock & Type P-Grip
The QRC II Pro comes from the factory with B5 Systems furniture, a favorite among serious AR shooters:
B5 Bravo 6-position stock – offers a solid cheek weld, QD sling points, and lightweight, streamlined styling.
B5 Type 23 P-Grip (often listed as Type P-Grip) – a more vertical angle and subtle texturing for better wrist alignment and control, especially when shooting from modern squared-off stances.
The adjustable stock lets you quickly tailor length of pull to your body, armor, or shooting position, while the upgraded grip provides a more comfortable, modern interface than basic mil-spec grips.
Optics-Ready Upper – Built for Your Glass
Instead of fixed iron sights, the QRC II Pro leaves the top rail clean and optics-ready:
Full-length Picatinny rail on the upper receiver for red dots, LPVOs, prisms, or magnified scopes.
Free-float handguard with additional rail for backup sights or offset red dots if desired.
This lets you select exactly the sighting system you prefer, from lightweight red dots for close work to LPVOs and higher magnification optics for mid-range precision.
Thoughtful Details & Made-in-USA Quality
Every part of the Bushmaster QRC II Pro 0010018BLK is geared toward dependable, real-world use:
30+1 round capacity with the included Bushmaster aluminum magazine.
Semi-automatic action for familiar AR-15 manual of arms.

Proudly made in the USA, with Bushmaster’s reputation for quality and support standing behind the rifle.
