WM Black SIG MCX Spear LT SELF ASSEMBLY MWS(ZET System) GBBR Gel Blaster

Bring the cutting edge of modern rifle design into your loadout with the WM Black SIG MCX Spear LT MWS (ZET System) GBBR Gel Blaster Kit. This premium gas blowback rifle kit is modelled after the renowned SIG MCX Spear LT platform, offering authentic styling, robust polymer and metal construction, and a highly realistic operation thanks to the ZET blowback system.

Delivered in two separate boxes, this is a self-assembly kit, giving experienced players the satisfaction of assembling their blaster, which gives invaluable understanding of the product, how it fits together and more important, how to strip it doen for essential lubrication etc. Once assembled, the MWS ZET system provides crisp recoil, responsive trigger action, and consistent power — creating one of the most immersive gel blaster experiences available. Finished in Operator Black, the SIG MCX Spear LT stands out as both visually striking and performance-driven, ideal for players seeking realism, durability, and style on the skirmish field.

Engineered for realism and durability, the MCX Spear LT pairs a lightweight profile with heavy-duty internals: a Stainless Steel Bolt Carrier Group, steel trigger box, adjustable hop-up inner barrel. WM’s quality control guarantees consistent performance through thousands of cycles. Ideal for mil-sim, field play, and discerning collectors.

The MCX Spear LT is built around a modular design, allowing quick swaps of handguards, stocks, and other components without special tools. This flexibility means you can adapt the rifle for close-quarters, field play, or display setups with ease, just like the real MCX platform.

The MCX Spear LT is fully ambidextrous, featuring mirrored controls on both sides of the rifle. Fire selector, magazine release, and bolt catch are all accessible from either hand, giving left- and right-handed users equal control and speed. This ensures seamless handling in dynamic scenarios and a truly modern rifle experience.

The MCX Spear LT features a robust foldable stock for compact carry and secure lock-up, switching instantly between close-quarters agility and full-length stability.

We also recommend, either of the two Ultra Hard Gels to run with this Blaster. Though, in our opinion the Predators will give a slightly better performance.
