SOT Javelin-8.5″ SD (M-LOK) Rail System:

The SOT (Javelin-8-M-LOK)}” Rail System has an overall length of 8.5″. It is  a cutting edge, highly refined rail system that blends state of the art custom precision CNC machining along with ultra aggressive Stealth like design. The Javelin is machined out of a one piece billet aluminum extruded rail which is much stronger and more rigid than 2 piece rail systems. The Javelin series boasts with aggressive good looks as well as being tough enough to handle any mission all while weighing in at only 8.1oz.! The Javelin-8.5 SD M-LOK } Provides (3) Sling Swivel Attachment Points in total; (3) QD points on the Rear that are integrated into the left, right and bottom of the rail.

Designed to be used in with a (Micro/Low Profile Gas Block) on a (Pistol Length gas system). This rail system gives the user a light weight more ”rigid” and modular way to mount accessories to their AR15 platform.

Our rails are designed to work and function with other (MILSPEC) components. Beware there are several companies in the firearms AR15 industry that make nice looking parts that are not (MILSPEC) and most importantly do not feature the required (MILSPEC) features in order to accept (MILSPEC) components. For reference you can take a look at our (Billet Upper) and notice the (MILSPEC) “recessed” cut near the front just behind the threads on the upper which is required to accept our rails. We have been told our rails can be slightly modified to work with the F-1 Billet and some other NON-MILSPEC uppers. While we have seen it done before, we cannot recommend this as a manufacturer.

    this rail is insanely gorgeous, wickedly seductive and highly functional. I fell in love and wanted one as soon as I laid eyes upon this feat of engineering. Took me a while but I couldn’t be happier. currently using in conjunction with an 8.5″ 5.56 barrel + MackBros 762 suppressor (which snuggles perfectly into the rail (~1/2″) and makes (IMO) the dopest little pistol around. If you’re in the market, do not hesitate. It’ll make you smile every time you see it, not to mention every time you use it.
