Masterpiece Arms is displaying this offensively colored bullpup with no plaques or press releases partnered with the mock-up. Working with Charles St George they are working on a gun that is visually similar to his earlier design, the Bushmaster M17S, but chambered in .22 Magnum.
The firearm doesn’t have a release date and looking at the gun it was hard to tell if it was a mock-up or a gutted prototype. It is expected to have a 50 round capacity, though it is not currently clear if this will be in a rear-fed drum. It is too soon for them to answer the questions I tested on them, but I’m looking forward to Charles adding a matching .22 to his Micor .50 BMG design.
