The all new Killjoy Industries Adjustable Picatinny Rail APR V2 is now available. Perfect for mounting scopes and sights to your paintball marker or airsoft gun. In a nutshell, paintballs drop in their trajectory over a short distance due to lack of speed and gravity. Most sights, red dots, and scopes were not designed with paintballs in mind. So once a sight got dialed in (if it even got dialed in), it would only be good for one distance. That meant guessing at any other distances.
