[Tokyo Marui] Mk18 Mod.1 Gas Blowback (Latest Lot/Released June 19, 2025)

The latest CQBR equipped with BLOCK2 parts

Among the CQB (close quarters combat) models, which are short-barreled versions of the M4A1, the "Mk18 Mod.1" equipped with an accessory part called BLOCK2 has been released as a gas blowback model!
Equipped with new mechanisms such as the Z System developed for the M4A1 MWS, it achieves both high durability and operational performance. Furthermore, the front sight post has been eliminated, and a longer rail handguard (RIS2) is included as standard. This model is meticulously recreated down to the smallest detail, including the rail-mounted sight, the 10.3-inch full-floating barrel fixed only to the receiver, and the different colors of each part.

Key Features

• Realizes powerful blowback

  It features a new blowback engine with a large piston measuring approximately 19mm in diameter. The bolt operates in conjunction with the firing, allowing you to enjoy an unprecedentedly powerful recoil shock.

• High durability

  The new Z-system prevents wear and tear on the bolt catch, while the piston absorber and friction relief bolt roller reduce the strain on internal parts caused by bolt operation, and the barrel clamp mechanism prevents loosening due to recoil and keeps the barrel centered at all times improve durability against strong recoil shock.

• Realistic moving gimmick

  It faithfully reproduces the same functions as the real thing, such as loading the first bullet by operating the charging handle, operating the bolt catch after opening the bolt and changing the magazine, and an enhanced stock that can be adjusted to six different lengths.

• Officially approved by Daniel Defense

  The metal RIS2 rail, with mounting rails on all four sides of the handguard, is officially approved by Daniel Defense, which has a proven track record of being officially adopted by the U.S. military. It is possible to mount various optional parts compatible with the 20mm wide rail.

• Color reproduction and special surface treatment

  The rail handguard, front sight, and stock all feature the same FDE color scheme as the real thing. The metal rail handguard is anodized for excellent abrasion resistance, recreating its color. The upper and lower frames and bolts are finished with Cerakote, a coating with a strong abrasion resistance. Enjoy the texture of the real thing.

• Adjustable folding front and rear sights

  The front sight can be adjusted up and down, and the rear sight can be adjusted left and right, and is foldable to allow for the use of optical sights. In addition, since it is attached via a mounting rail, the mounting position can be changed or removed.

• Compatible with various muzzle options

  By removing the flash hider from the muzzle, you can attach a muzzle option with a 14mm reverse thread, such as a silencer.

• Aluminum die-cast magazine

  The die-cast aluminum magazine holds 35 rounds and reproduces the weight of a fully loaded magazine.
