Knights Manufacturing's first solution to the MWS requirement are described on
the RIS and RAS Page. These units use MIL-STD-1913 "Picatinny" rails in special grips that replace the factory handguards of AR15 and M16 weapon systems to allow the addition of military attachments such as lasers, forward pistol grips, optics, masterkey shotguns, and m203 grenade launchers. This page provides a description of these two units including distinguishing characteristics and markings. Related to this page, I have also created a page that discuss using a M5 RAS on an
Armalite AR-10 as well as on a
Bushmaster Dissipator.
