I recently purchased a CX4 Storm and couldn't be happier! What a great gun for tactical, close quarters work, and all around fun. I've added the Hakko Panorama red dot site, Harris Bi-Pod, and custom sling. At first I was a little uneasy about drilling holes to mount the top rail, but the instructions were clear and everything was perfectly aligned.
I've got two AR15 friends that have a new CX4 on order to replace their .223 money eating machines.
Buy it! You'll love it!
