The M4A1 Carbine Gas Blowback Rifle, developed to meet the stringent requirements of USSOCOM (United States Special Operations Command), is now available as a gas blowback machine gun. This model incorporates advanced mechanisms such as the Z system, initially developed for the M4A1 MWS, ensuring both high durability and exceptional performance. The M4A1 Carbine features a handguard with a double heat shield and an accurately reproduced early model barrel shape, emphasizing realism and functionality.
 
Powerful Blowback Action:
The M4A1 Carbine Gas Blowback Rifle is equipped with a new blowback engine that utilizes a large piston with a diameter of approximately 19 mm. This system delivers a robust recoil shock, enhancing the shooting experience.
 
Enhanced Durability:
The Z-system prevents wear on the bolt catch, while the piston absorber and friction relief bolt roller minimize strain on internal components caused by bolt action. Additionally, the barrel clamp mechanism keeps the barrel centered to prevent loosening due to recoil, significantly improving durability.
 
Realistic Functionality:
This model faithfully replicates the operations of the real M4A1 Carbine, including loading the first round by operating the charging handle, opening the bolt and operating the bolt catch after magazine changes, and an adjustable stock with six length settings. The carrying handle is removable, and field stripping for maintenance is performed similarly to the real firearm.
 
Attention to detail:
The handguard's interior features a double heat shield, and the outer barrel replicates the early model's design, including the narrower section that fits inside the handguard. Special care has been taken to reproduce parts not visible from the outside, enhancing authenticity.
 
Military Spec Cerakote® Finish:
The upper and lower frames, as well as the bolts, are coated with Cerakote®, a strong and abrasion-resistant coating, providing a texture and finish similar to the real M4A1 Carbine.
 
Adjustable Sights:
The front sight is adjustable up and down with the included adjustment tool, while the rear sight can be finely adjusted vertically and horizontally using the dials.
 
Muzzle Customization:
The muzzle compensator is removable, allowing the attachment of various muzzle options with a 14mm reverse thread, such as silencers.
 
Die-Cast Aluminum Magazine:
The die-cast aluminum magazine holds 35 rounds and replicates the weight of a fully loaded real magazine, adding to the realistic experience.
