We have always wanted an affordable Personal Defense Weapon (PDW) for airsoft and the Echo 1 M4 CQB XK made our dreams come true. The M4 CQB XK is quite the compact little hellion that we %100 expect from Echo 1 USA's design team. The rotary sights allow you to easily aim it and adjust it for different ranges as well as you can remove them completely if needed to have simply a flat rail for any kind of Picatinny Weaver mounted optic. The quick detach sling adapter is a huge plus as well so get a sling for this so you can set it on your side and use it as your main or as your side arm.

Pre-order now so you can get your mitts on the CQB XK before anyone else, besides us of course.

I own this gun and and completely satisfied with it. The velocity and range are actually much better than what this site says. I was able to chronograph my gun and it was shooting in the high 360's to the mid 370's in FPS and a few times it spiked to 382 FPS. The effective range is actually well over 130 feet, but the sight the gun come with are junk so i defiantly recommend getting a red dot scope or the like for this.
