Tokyo Marui M4A1 Carbine GBB

U.S. SOCOM (United States Special Operations Command) is known for demanding the highest performance from their firearms compared to any other military unit in the world.
The M4A1 Carbine was developed in response to their demands, and is now available as a GBB machine gun.

New mechanisms, such as the Z-system developed for the M4A1 MWS, have been added to achieve both high durability and operational performance. In addition, the inside of the handguard has double heat shields and the barrel shape of the early model has been replicated to ensure a realistic look.

With the barrel guide sold by ORGA it is possible to replace the handguard with an external one.

Intense Blowback

Equipped with a new blowback engine featuring a large piston of approximately 19 mm in diameter. The bolt is triggered when firing, producing an unprecedentedly strong recoil shock.

High Durability

The new Z-System mechanism prevents wear and tear on the bolt catch. The piston absorber and friction relief bolt roller reduce the load on internal parts caused by bolt actuation. The barrel clamp mechanism prevents loosening due to recoil and also centers the barrel, improving durability against intense recoil shock.

Realistic Handling

This model faithfully replicates the functions of the real firearm, such as loading the first round by operating the charging handle, bolt catch operation by opening the bolt and changing the magazine, and an enhanced stock that can be adjusted to six different lengths. In addition, the carrying handle can be detached and field stripping (normal disassembly for maintenance) can be performed in a manner similar to the real firearm.

Realism Beneath the Exterior

We have also focused on the replication of parts that are not visible from the outside. The inside of the handguard has a double heat shield and the outer barrel replicates an early model with a narrower section that goes inside the handguard.

Cerakote Mil-Spec Paint

The upper/lower frames and bolts are coated with Cerakote, which has a strong coating film and excellent abrasion resistance. The texture feels just like the real thing.

Adjustable Front/Rear Sight

The front sight can be adjusted up and down with the included adjustment tool. In addition, the rear sight can be precisely adjusted up, down, left, and right using dials.

Compatible with Various Muzzle Options

By removing the muzzle compensator, a silencer or other 14mm reverse threaded muzzle option can be attached.

Aluminum Die Cast Magazine

The magazine is made of die cast aluminum and holds 35 rounds, replicating the weight of a fully loaded magazine.
