Blowback System
Among the CQB (close quarters combat) models, the "Mk18 Mod.1" is a gas blowback model equipped with accessories called BLOCK2, a short-barreled M4A1.
By incorporating new mechanisms, such as the Z System developed for the M4A1 MWS, it achieves both high durability and operational performance. The front sight post has been eliminated, and a longer rail handguard (RIS2) is included as standard. 
This model features rail-mounted sights, a 10.3-inch full-floating barrel fixed only to the receiver, and different colored parts
Realizes powerful blowback. It features a new blowback engine with a large piston measuring approximately 19mm in diameter. 
The new Z-system prevents wear and tear on the bolt catch, while the piston absorber and friction relief bolt roller reduce the strain on internal parts caused by bolt operation
Adjustable stock with six customizable length settings.
The metal RIS2 rail, with mounting rails on all four sides of the handguard
Compatible with the 20mm wide rail.
Adjustable folding front and rear sights
The die-cast aluminum magazine holds 35 rounds
Color reproduction and special surface treatment
The rail handguard, front sight, and stock all feature the same FDE color scheme as the real thing. The metal rail handguard is anodized for excellent abrasion resistance, recreating its color. The upper and lower frames and bolts are finished with Cerakote
