M4 CNC Steel bolt & NPAS Original nozzle for WE AR GBB

Steel slide with plastic NPAS loading nozzle for WE M4/M16/T91/HK416 GBB guns.

The slide is made by precision machining on CNC machines from hardened steel. The package also includes a steel bolt catch. Its higher weight (250 g compared to the original slide's 200 g) of the slide increases the recoil of the weapon.

The loading nozzle with NPAS (Negative Pressure Air System) allows you to regulate the power while increasing the life of your gun.

The manufacturer recommends using this assembly with Maple Leaf buckings, which will ensure excellent assembly tightness and better hop-up effect.

NPAS set is simply put an adjustable flap (valve). The user must insert the key from the front of the charging nozzle all the way to the flap and turn it to regulate it. How much gas goes into the barrel when the gun is fired and how much is left for blowback can be adjusted. Thus, the more gas that goes into the barrel, the more power will be produced, but the recoil will decrease and vice versa.
