Tokyo Marui Mk18 Mod 1 Gas Blowback Rifle RIS2

Tokyo Marui Mk18 Mod 1 Gas Blowback Rifle RIS2 is a premium airsoft gas blowback platform built for players who want a realistic bolt cycle, a strong recoil impulse and a modern CQBR style layout. Based on the M4A1 MWS family, it follows the BLOCK2 spirit with a Daniel Defense approved RIS2 metal rail, a compact 10.3 inch outer barrel and plenty of 20mm rail space for optics, lights and other accessories.

Strong blowback feel and realistic controls

The replica uses a blowback engine with a large piston of about 19mm diameter. The bolt reciprocates with every shot, delivering a pronounced kick and a lively feel in both semi and full auto. Handling is also realistic: operate the charging handle to chamber, experience bolt lock on empty, then release the bolt catch after a magazine change.

35 plus 1 capacity magazine

The supplied magazine is an aluminium die cast type, rated at 35 rounds, with 35 plus 1 when one BB is already chambered. This capacity suits CQB and realism oriented play, helping you track your shots, manage gas consumption and keep reloads compact on your kit.

Z System durability package

To handle intense recoil, Tokyo Marui includes the Z System: design features aimed at preventing wear on the bolt catch and reducing stress on internal parts. Key elements include a piston absorber, friction relief bolt rollers and a barrel clamp mechanism that keeps the barrel centred and helps prevent loosening from repeated recoil cycles. The goal is improved longevity under frequent skirmish use.

Field ready ergonomics and finish

The stock adjusts across six positions for comfortable length of pull, and the flip up sights are adjustable and can be folded when running a red dot or scope. Tokyo Marui also focuses on surface treatment, with a rugged Cerakote style finish on the receiver and bolt, plus carefully matched colour tones on rail, sights and stock for a true Mk18 look.

RIS2 rail interface and muzzle options

The RIS2 metal handguard provides four sided 20mm rail surfaces for accessories. At the muzzle, removing the flash hider reveals a 14mm reverse thread, ready for common airsoft suppressors and tracer compatible adapters. The platform is specified for 6mm BBs in the 0.20 to 0.25g range and uses a dedicated Tokyo Marui gas type as recommended by the manufacturer.
