ARP556 CQB Polarstar HPA M4

ARP556 CQB Polarstar HPA M4

A compact ARP556/M4 platform designed for quick transitions—5in barrel & adjustable stock. Great for players who want a short overall length without giving up familiar M4 ergonomics.

Part of KA Tech’s Liquidation Sale: professionally built rifles with brand new HPA engines and refurbished bodies.

If you'd like to upgrade the hop-up, bucking, inner barrel, trigger, or IGL, we can do that before shipping the rifle.

All rifles come as shown. FCU, battery, airtank, regulator, airline, and magazines are sold separately.
