XM8

Note: This was not a reliable weapon in for the US Army
The XM8 is a selective fire 5.56x45mm NATO assault rifle, firing from a closed rotary bolt. Its design and functioning is similar to that of the Heckler & Koch G36 assault rifle, of which it is a derivative. It is reported to be capable of firing 15,000 rounds without cleaning or lubrication and up to 20,000 rounds before barrel replacement. The sight is much more than a 1.5x red dot scope, including IR lasers and pointers as well. The baseline XM8 carbine (with its integrated sight), for example, can be compared to an M4 carbine with a host of previous-generation electronic add-ons like the AN/PEQ-2, Aimpoint CompM2, Advanced Combat Optical Gunsight or ACOG, and/or BUIS. Without the advantage of the next-generation combined electronics sight, the XM8 would be both heavier and more expensive than the firearms it is intended to replace. The XM320 grenade launcher, intended to be used with the current M4/M16 firearms as well as the XM8 family, includes feature enhancements. The benefit of PCAP (Picatinny Combat Attachment Points), however, is the precision of the accessory's connection with the body of the weapon. Additionally, most standard accessory functionality is built-in to the XM8. Where functionality was missing, it was anticipated that accessories would be redesigned to utilize PCAP. In the new OICW Increment One competition, the Army has left the choice of attachment technology up to the manufacturer, with requirements built into the RFP as to the ability of sights to maintain their zero.
