This light and compact carbine was designed to be completely and easily adaptable to the needs of most shooters. The operating handle, safety and magazine release are reversible and give you the opportunity to train or shoot right- or left-handed, while case ejection can also be switched from right to left. The length of pull is adjustable (one spacer included), making the CX4 easily and intuitively come up to the shoulder of most shooters. The aperture and post sights are user-adjustable, meaning that you can train with (or switch) your favorite brand of ammo without taking the carbine to a gunsmith. And after a day at the range, this carbine is a snap to take apart and reassemble, while its ultra-tough construction and surface treatment make it stand up to the hardest use.
