The Ataman M2R is another awesome rifle on the market and we've been asked to make a single shot tray to fit the growing demand.
This tray, is designed to slide right into the spot where your factory magazine would normally go and even has a setscrew with a soft tip to lock it into place just like the factory magazine does. Just a few turns with an Allen wrench and your set to load those longer more stable bullets than will fit in the factory magazine.
