Built by Utah-based Desert Tech, their modular, multi-caliber semi-automatic MDR bullpup looks pretty sweet in action.
The MDR has been under development for the past several years and offers chamberings in .223 Wylde, .308 Win, and .300 BLK, all with an overall length of just 26.2-inches while keeping a 16-inch barrel. The chassis can accommodate each caliber in turn through the use of conversion kits that come with a barrel assembly, bolt head, magazine, and magazine well adapter if needed.
In the above video from YouTube gun channel Highjak86, the forward-ejecting MDR production models seem to deliver the goods both left and right-handed as it is fully ambi. And yes, we did say production models.
