ZWQ S400 Overkill Kit (PHYSICAL ITEM) MULTIPLE OPTIONS

from $35.00

The ZWQ S400 Zebra is on par for being one of the most electrifying blasters of 2026.  What is, essentially, an injection molded, overcharged Lynx, the S400 is capable of hitting insane speeds with a light prime and a barrel upgrade.  We had nearly no notes regarding the design except for a few recommendations that we decided to address in our kit.  

For starters, our original mag well design has been updated for the kit, offering a redesigned mag release level that is now kept more flush with the body of the blaster in order to prevent accidental release (if you have already purchased the magwell, please email us so we can send you a complimentary replacement lever).   

in addition to giving the blaster the ability to use Talon magazines, we decided to lower the picatinny rail a couple of centimeters in order to make Using an iron sight or optic sight more feasible.   

The priming grip that we used for the NPX kit has been modified and adjusted to work with the s400, offering a longer grip that allows you to not have to worry about accidentally slamming your knuckle into the trigger guard.  

A pair of optimized iron sights for the offset front end rail are also included.   

Last but certainly not least is a barrel shroud that helps to conceal longer barrels to provide more of a streamlined look.  Shrouds are available in two sizes;  stock to 500mm and 550 to 600mm barrels. Shroud has three NATO spec weaver rails mounted on opposite sides as well as the top. Bottom of shroud features several M-LOK slots for easy accessory installation.

 Both sizes have customization options (Larger Shroud has a $5 upcharge due to filament use).

SHROUD IN IMAGE IS DESIGNED FOR 500mm barrels and up.  Laser Sight NOT INCLUDED
