The DMK22C is a dedicated .22LR, semi-automatic, rifle platform that is optimized for realistic training, accuracy, and that offers nearly limitless customization. The DMK22 features a patented barrel adaptor that allows for the use of aftermarket 10/22 barrels, capable of accommodating any type of performance requirement. Also, the DMK22 employs a patented bolt lock to keep the action open when the magazine is removed, allowing for the same reloading manual of arms as a centerfire AR-15. Additionally, the DMK22C is compatible with nearly all AR-15 upgrades and furniture.
