The M4A1 carbine was developed in the mid-1980s and is a short-barrelled version of the M16A2. The M4 carbine was developed due to the need to have a more compact and modular weapon system that would be easier to manage within fighting vehicles and for roles such as close quarters combat within restricted space. The M4 carbine has been utilised by numerous militaries around the globe and it has been used heavily by US special forces such as the Navy SEALS.

This airsoft gas blowback rifle by Tokyo Marui is a stunning replica of the real M4A1 carbine and is built with the legendary craftsmanship of Tokyo Marui. The M4A1 incorporates Tokyo Marui’s innovative ZET system which was developed for the MWS, this system helps improve the durability and function of the internal parts by reducing friction and wear by using piston absorbers and bolt rollers to prevent damage and keep your gun functioning for longer! The M4A1 carbine utilises a 19mm piston which improves cycling, gas efficiency and adds high impact recoil with every shot.

The Tokyo Marui M4A1 carbine features adjustable hop-up, a 6-position adjustable stock, adjustable front and rear sights and sling attachment points. Tokyo Marui have been meticulous with their attention to detail and have made this a true to life replica by incorporating things such as a barrel clamp to keep the barrel centred during heavy use, incorporated a double heat shield inside the handguard, have made the airsoft gun field-strippable like the real gun and have even added a removable carry handle to allow the attachment of optics.

If the airsoft gun was not good enough Tokyo Marui have also added Mil-Spec Cerakote to the whole gun to prevent scratching! You will also find a 14mm CCW threaded barrel which allows for the attachment of suppressors or tracer units and also aluminium die-cast magazines which have been made to have the same weight as a real magazine that is fully loaded!

If you are looking a unique gas blowback rifle that is incredibly well-made, durable and gas efficient then the Tokyo Marui M4A1 Carbine GBBR is the airsoft gun for you!
