A new era of M4 Shorty that evolves flexibly

A CQBR replaces the upper receiver with each barrel to make it a short barrel of 10.3 inches in order to make the M4 compatible with close quarters combat (CQB = Close Quarter Battle) in a narrow room. Of the three versions of CQBR, the model called "Block1" is available in his gas blowback machine gun! By installing new mechanisms such as the Z system developed for the M4A1 MWS, we pursued the reality of shape and texture while achieving both high durability and operating performance. In addition, the scalability for optional parts has been enhanced, making it easy to handle even in narrow spaces.

Major features

• Delivers powerful blowback

  Equipped with a blowback engine that uses a large piston with a diameter of about 19mm. The bolt also operates in conjunction with the launch, and you can enjoy an unprecedentedly strong recoil shock.

• Realizes high durability

  A new Z-system that prevents wear and damage to the bolt catch, a piston absorber and friction relief bolt rollers that reduce the burden on internal parts due to bolt operation, and a barrel that prevents loosening due to recoil and always keeps the barrel centred. The durability against strong recoil shock has been improved, such as the clamp mechanism.

• Realistic movable gimmick

  It faithfully reproduces the same functions as the real thing, such as loading the first bullet by operating the charging handle, bolt catch operation after bolt opening and magazine change, and crane-type stock that can be adjusted in 6 stages. In addition, field stripping (normal disassembly for maintenance) can be performed in a form close to the real thing.

• Equipped with metal RAS

  Handguard Equipped with RAS (Rail Adapter System) with mounting rails on four sides, top, bottom, left and right. In addition to the standard KAC type vertical foregrip, various optional parts compatible with the Picatinny standard (20mm width) can be installed. In addition, the heat shield inside the RAS is also reproduced.

• Mil-Spec Paint Cerakote

  Cerakote, which has a strong coating film and excellent abrasion resistance, is used for the upper/lower frame and bolts. You can enjoy the texture just like the real thing.

• Adjustable front/rear sights

  The top and bottom of the front sight can be adjusted with the included adjustment tool. In addition, the LMT type rear sight can be finely adjusted by dialing up and down and left and right.

• Compatible with various muzzle options

  If you remove the muzzle compensator, you can install a muzzle option with a 14mm reverse screw specification such as a silencer.

• Aluminum die-cast magazine

  The magazine, which holds 35 bullets and is made of die-cast aluminium, reproduces the weight of a fully loaded magazine.
