(USED) Zion arms M4 Starter kit

PRODUCT DESCRIPTION Zion arms m4 with 5 midcap mags and Odin Speedloader

Internally this new R15 AEG features a version 2 gearbox with aftermarket compatibility! However, Zion Arms did their research and made sure this AEG was stacked out of the box! Featuring a quick change spring system, you are able to achieve the FPS that you desire to maximize the performance at your local field! The full metal rack piston increases the longevity and reliability. Zion Arms also includes a 6.03mm Tight Bore Inner Barrel and Rotary Style Hop Up Unit to fine tune your range and maximize accuracy! Of course Zion Arms would include their Nebula MOSFET out of the gate!
