Tokyo Marui M4 CQBR Block 1 MWS GBB Rifle in Black

Full-metal CQB power—no compromises, just pure realism. The Tokyo Marui M4 CQBR Block 1 MWS GBB is an airsoft rifle for players who demand the most authentic experience possible. Based on the US SOCOM CQBR platform, this gas blowback rifle is built to dominate close-quarters environments while still holding its own outdoors. With its shortened 10.5-inch barrel, modular quad-rail handguard, and snappy gas blowback engine, the Block 1 delivers responsive, high-impact performance with every trigger pull.

This rifle sits on Tokyo Marui’s revered MWS (Modular Weapon System) platform, known for its durability, realistic function, and clean internal design. The Z-System bolt lock reinforcement ensures longevity by reducing wear during full-auto fire, solving one of the common fail points of gas rifles. Pair that with a 19mm blowback engine and you’ve got one of the hardest-kicking, most responsive gas rifles available straight out of the box. The feel of each shot is immediate and tactile—every round fired feels earned.

Externally, this rifle is a head-turner. The full-metal receiver and outer barrel are finished in Cerakote® matte black, offering both realism and abrasion resistance. The handguard is a proper RAS quad-rail, ready to accept torches, lasers, grips, and any other 20mm attachments you want to throw on. Included flip-up LMT-style rear and adjustable front sights come mounted out of the box, and they fold down neatly if you decide to run optics. The included vertical grip is a solid bonus and a practical upgrade for CQB use.

Internally, the hop-up unit is tucked under the bolt and easily accessed without tools. It’s adjustable on the fly, letting you dial in for different BB weights—0.20g to 0.25g is the sweet spot for consistency and range. The 35-round die-cast magazine offers solid gas efficiency and a satisfying weight in hand. It’s built tough to handle the rigours of skirmishing, and it seats with a satisfying click that mirrors real steel M4 reloads.

The rifle’s six-position collapsible stock lets you shrink the overall length from 780mm to 698mm, perfect for navigating tight indoor corners or adjusting for different loadouts. Despite weighing around 3.2kg fully loaded, it remains well-balanced and easy to manoeuvre—especially when paired with a sling. The buffer tube is full-length and sling mount compatible, giving you flexibility to run your preferred gear setup.

Controls are fully ambidextrous where it counts. The mag release, bolt release, and charging handle all operate exactly like the real thing. Field-stripping is authentic too, making it a fantastic training tool for those crossing over from real steel or looking to simulate military drills with precision.

If you’re after a GBB rifle that blurs the line between training weapon and skirmish beast, the Tokyo Marui CQBR Block 1 is hard to beat. It’s compact, powerful, and built to outlast. Whether you’re clearing rooms in tight CQB kill houses or laying down semi-auto precision at longer range, the MWS system delivers performance you can trust. And if you spot it cheaper? Let us know. Our price match guarantee ensures you get the best value—because excellence shouldn’t come at a premium.
