The SOT (SOTAAR-10-M-LOK)” Rail System has an overall length of 10.3″; It’s newly refined features include a machined single one piece billet aluminum extruded rail which is much stronger and more rigid than 2 piece rail systems.  The SOTAAR-10 Provides (3) Sling Swivel Attachment Points that are integrated on the left and right side as well as on bottom.
Designed to be used in with a (Micro/Low Profile Gas Block on a Pistol or Carbine gas barrel). This rail system gives the user an ultra light but robustly strong and rigid way to mount various accessories available to their AR15 platform.

Notice: "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 (MILSEPC) 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 uppers but cannot recommend this as a manufacturer but have seen it done."
