Fire Control
The XM7 will be equipped with the XM157 Next Generation Fire Control System. The fire control allows for computer-aided ballistics, matching the round and weapon with the optic for better accuracy. The shooter can aim at the target, push a button on the weapon or optic and it will automatically adjust for distance and bullet drop, allowing the user to adjust fire rapidly.
The fire control has preprogrammed ballistics information and can be fit to nearly any small arms weapon system in the Army’s inventory.
Note
The XM7 NGSW-R includes a full-length MIL-STD 1913 rail for attaching optics, and the M-LOK® interface allows for the installation of additional rail segments at various locations. Multiple sling mounting points enable the use of different sling configurations.
