<p>The Only AR-15 that can be chambered in .22-250 Rem. The UMAR utilizes an extended length magazine well to accomodate the UMAR magazine allowing shooters the ability to utilize longer COL loads. This is especially applicable to the WSSM cartridges when wanting to load heavier bullets. This proprietary lower design still accepts MIL Spec upper receivers or various calibers and their appropriate magazines. The UMAR comes with one 5 round caliber specific custom magazine that will either fit the .22-250 or the WSSM/OSSM cartridge. Shown with optional ACE brand skeleton stock.</p>
