EVANIX REX-IBEX .50 is a serious big game rifle. This is built off of the REX Rifle but has a modern AR style and a longer barrel. This makes the gun easy to accessorize with your favorite accessories and the longer barrel gives you more power to push you into the deer size game at a little further distance than what was possible with the REX. This air gun also comes with a carbon fiber bottle so you dont need to keep track of fill probes. You also get a nice muzzle break to help you control muzzle flip, helping you stay on target. This Rifle checks a lot of boxes for most big game hunters.
