Interesting design work by Canadian DRC and Colt Canda. 5.56 lower bullpup weapon with long bolt travel, extreme rearward magazine, downward ejection just forward of the magazine. Upper module is expected to be either a 3 round 40mm or some sort of shotgun with multiple rounds, but there's noise about a 20mm special round module (hence the possible OICW comparison). Image shows the benchtest prototype, with variable handgrip positioning and a single shot 40mm test module.
