CNC receiver (body) type C is inspired by real firearm AR15 (M4). This CNC receiver is manufactured from solid block of aircraft aluminum (Dural) EN AW 7075 T651, which has better strength (590mPa), than common construction steel (390MPa). Thanks to the used material, this receiver has much higher durability than common casted zinc-aluminum alloy receiver. Manufacturing one of those CNC receivers requires a lot of time and material. CNC receivers have much more material on every part for best strength and resilience. Because of used material EN AW 7075 T651, our CNC receiver is very lightweight and resilient from braking. Because of reinforced parts on our receivers, uppers and lowers from other manufacturers are not interchangeable.
