One of the first bottom box fed markers on the scene back in 07. I fabricated an existing electronic sensor hopper to feed balls up a tube into an inverted breach, rather than the typical top load systems, effectively eliminating the top-heavy balance and obscured sight peripheral limitations. This was an evolution at the time and nothing like it was available to the market. Dye later followed the pioneering few of us and created the DAM, which is one of the hottest selling milsim markers of today, which features a bottom feed system similar to my version.
