C.A.T. Airsoft offers the C.A.T. Versatile-8 SMG as a compact, user-friendly airsoft gun featuring an 8-inch outer barrel with a removable .3-Lug styled tip revealing a 14mm reverse thread, and an adjustable length of 585-690mm. Weighing 2000g with a 200mm inner barrel, it offers ambidextrous controls, intuitive 93-round MP5-style magazines with interchangeable AK or M4 housings, and a five-position, one-touch extendable PDW wire stock with an integrated Picatinny rail and battery space for Mini-S size Lipo batteries (7.4v 2000mAh 30C recommended).

Constructed from durable PA66/GF30 resin, its receiver is lightweight and incorporates a streamlined design based on feedback from shooter Mac Sakai, including a standard MAC grip. A standout feature is its world-first mechanical "variable" pre-cocking mechanism for instant semi-automatic firing without electronics, utilizing a MAP sector gear for precise cutoff cam angle adjustments. The SMG also boasts a split-type gearbox for realistic takedown, a microswitch system with an IWS Trigger for a crisp feel, and a high-performance Japanese-made INAZUMA motor, ensuring custom-gun level performance and stable quality after being test-fired at 30m.
