TheXM307 Advanced Crew Served Weapon (ACSW) was a developmental25 mm belt-fed automatic grenade launcher with programmableairburst capability. It is the result of theOCSW orObjective Crew Served Weapon project. It is lightweight and designed to be two-man portable, as well as vehicle mounted. The XM307 can kill orsuppress enemy combatants out to 2,000 meters (2,187 yd), and destroy lightlyarmored vehicles,watercraft, andhelicopters at 1,000 meters (1,094 yd). The project was canceled in 2007.[1][2]
The system was under development byGeneral Dynamics Armament and Technical Products for the U.S. ArmyTank-Automotive and Armaments Command (TACOM). As a part of theSmall Arms Master Plan (SAMP) program, it is intended to either replace or supplement theMk19 automatic grenade launcher and theM2 heavy machine gun. It fires 25 mm point-detonating andair burst style ammunition, includingHE, andHEAT at a cyclic rate of 260 rounds per minute and has an effective range up to 2 kilometers.[3]
The primary feature of the XM307 is its attenuatedrecoil system. The weapon controls recoil to a degree that a largetripod and heavysandbags are not required to effectively employ this weapon. Because of its reduced recoil impulse and light weight, other mounting options are possible, such as small unmanned vehicles and aircraft. The XM307's airburst rounds make it much easier to bypass walls protecting enemies that could causecollateral damage if fired upon directly. Operators do not have to shoot through the wall, just through an opening or over the top to kill the people behind the cover, leaving the structure of the building intact. An additional feature of the XM307 is that it can be converted into theXM312, a 12.7 mm (.50)-caliber version forinfantry and light anti-armor support in under two minutes (1 minute, 42 seconds).

ARemotely Operated Variant (ROV) for theFuture Combat Systems family of vehicles is also under development.[4] The weapon system, which would be mounted on the vehicle, will be remotely operated from within the vehicle.
In May 2004, the development phase was funded through FY 2007.[2]In December 2005 funding was granted for aremote-control vehicle variant.[4]However, in 2007 the project was canceled due to the low rate of fire of the prototypes.[5]
