The US military understood that the M4 carbine and M16 were not suitable for all roles that they might be used in and therefore they started looking for a way to adapt the weapons to increase functionality. It was planned to change the receivers on the M4s to include CQBRs which are known as SOPMOD (special operations peculiar modification) Block II kits. The kits shorten the rifles down and thus allows them to have improved functionality in close-quarters combat whilst still retaining the range and stopping power of a military calibre rifle. The MK18 Mod.1 was born and is now heavily utilised by the US Navy, in particular the US Navy SEALS.

This airsoft gas blowback rifle by Tokyo Marui is a stunning replica of the real MK18 MOD.1 and is built with the legendary craftsmanship of Tokyo Marui. The MK18 MOD.1 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 MK18 MOD.1 utilises a 19mm piston which improves cycling, gas efficiency and adds high impact recoil with every shot.

The Tokyo Marui MK18 MOD.1 GBB Rifle features full Daniel Defense markings on the gun, with a fully licensed Daniel Defense RIS2 rail system included. The MK18 also features a 10.3-inch free floating barrel, a 6-position adjustable stock, multiple sling points and adjustable flip-up front and rear sights. There are integrated rail systems throughout the gun, and these have been treated with Alumite in order to improve their durability and scratch resistance. The MK18 MOD.1 operates like the real firearm requiring you to reload using the charging handle when changing magazines and the airsoft gun even field strips like the real MK18 MOD.1.

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 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 special forces gas blowback rifle that is made to the absolute highest standards in the airsoft market, then the Tokyo Marui MK18 MOD.1 Gas Blowback Rifle is the airsoft gun for you!
