Basic Information
The weapon ironically uses a combined basic layout of combining an XM-25 weapon, and an XM8 compact weapon at the front, reversing the original XM29 concept. The weapon, using a 12.5 inch polygonal barrel, is capable of delivering a 6.8mm Remington round at 760 m/s, which still holds 2116 joules or the original energy present in a 6.8x43mm Remington SPC. Although the barrel possess an enlarged diameter, the 6.8mm remington's original ability to fit into a 5.56mm designed weapon allows it to be easily applied to the underbarrel weapon. In addition to these, the weapon uses the top receiver of an Ares Shrike unit, that's been trimmed down to fit the extension of the rifle.
