Description:
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.
