This Complete Upper Receiver Kit by KWA is designed for the new Ronin 2.5/3.0 Series of AEGs, and creates a more versatile and customizable platform. The overall lightweight construction makes it perfect for turning tight corners, while still delivering enough power and accuracy to send high power shots to your enemies. This kit features an 18 inch barrel with an integrated lightweight metal 1 inch Keymod rail that sits on a one piece full metal upper receiver. Utilize the Keymod rail to accessorize your KWA rifle any way you please, by adding your favorite optic or tactical accessory. KWA outfitted the barrel with a 6.05mm brass inner barrel and bucking, and is capped with an orange flash hider. The one-piece rotary hop-up makes it quick and easy to adjust the spin on the BB to account for wind direction and target range.
