SOT Disintegrator-9″ (M-LOK) Rail System:

The SOT (DISINTEGRATOR-9-M-LOK)” Rail System has an overall length of 9.2″. It is a new cutting edge, highly refined rail system that blends state of the art custom precision CNC machining along with ultra aggressive Stealth like design. The DISINTEGRATOR is machined out of a one piece billet aluminum extruded rail which is much stronger and more rigid than 2 piece rail systems. The DISINTEGRATOR series boasts aggressive good looks as well as being tough enough to handle any mission all while weighing in at only 5.8 oz.! The DISINTEGRATOR-9 M-LOK Provides (3) Sling Swivel QD Attachment Points in total that are integrated into the Left, Right and Bottom of the rail. See more..
