KWA Upper Receiver Kit

The Ronin 15 Carbine complete upper receiver comes ready to drop onto your AEG 2.5 or AEG 3, and comprises one component of the first widely customizable AEG line, the KWA Ronin M-Series.

The RN-15 Carbine is just as comfortable in an indoor CQB field as it is at a 3-day outdoor MilSim op, and features a 15 inch barrel setup with plenty of real estate on its sleek, lightweight aluminum KeyMod free float rail. It makes a great alternative to the standard RM4A1/VM4A1, or the Ronin 6 PDW setup.

This complete assembly comes with a solid, one-piece upper receiver and a Japanese 6.05 semi-tightbore barrel, along with our one-piece rotary hop-up, so it’s ready for a super-quick ten-second installation on your RM4 or VM4 AEG. The Ronin’s aggressive styling is complemented with a black metal alloy mock suppressor, right out of the box.
