The Valken Tactical Alloy Series Mk.III is our carbine variant in our new premiere line of full metal AEG rifles. The durable high quality aluminum alloy bodies are milled to finish and hard coated to create a tough exterior, combined with a mills spec CNC'd free floating M-LOK rail system, and a 1 piece metal lightweight outer barrel. Inside is a Ver. 2.1 Gearbox, with a micro switch trigger system designed and tested with 11.1v LiPo's that presents a solid trigger break and reset for fast response. The gearbox also features a low resistance steel wire harness that clearly indicates positive from negative. The inner barrel assembly is a 70D full seal bucking, polymer hop up unit with precise adjustment, and a carbon steel barrel the MK.III is the perfect ranged rifle. And with 15" of rail, not one inch is wasted for attaching optics and accessories.
