      You made me question myself for a microsecond!



      "Knight's Manufacturing Company (KMC) has answered the Modular Weapon Systems (MWS) concept with a couple unique systems. The two most common are the Rail Interface System (RIS) and Rail Adapter System (RAS). Both of these units use MIL-STD-1913 and MIL-STD-1913 Update Notice 1 "Picattinny" rails incorporated into innovative forend rail assemblies to replace the factory handguards of the host SR-15(AR-15), M-16, and SR-25 weapon systems and provide attachment points for a variety of weapon system accessories.

      The RIS and RAS units are similar in that they consist of two major components: a top component consisting of top, left, and right quadrants, and a bottom component consisting of a bottom quadrant. Each quadrant contains a MIL-STD-1913 rail that can be used to attach a variety of weapon accessories. Differences between these two units occur in the way that they attach to the handguard cap and delta ring/barrel nut, how the units are numbered, and the types of barrels that they can be used with.


      Rail Interface System (RIS) (KAC P/N: 94297)

      The RIS is the older version of the two systems and is numbered T-L-R-B (top- left-right-bottom) in odd numbers 1 - 13 beginning at the front sight and ending at the upper receiver. The RIS system works with a wide variety of barrel contours and mounts like a conventional handguard except for an adjustable metal tab, at the handguard cap, that squeezes the two halves together. At the rear, the RIS unit is held in place by the delta ring.

      The biggest advantage with the RIS system is that it is able to accommodate a wide variety of barrel profiles while the disadvantage is that the RIS doesn’t clamp to the weapon as solidly as the RAS system. Just the same, the Navy SEALS reportedly prefer the RIS over the RAS system for the advantages described above.


      The Navy SEALS’ solution in the future will be the Knight's free floating RAS, a one piece extrusion that I describe in great detail on the next page of this series. The FF RAS will allow the Navy SEALS to use a variety of barrel profiles including integrally suppressed weapons that is not possible with a standard RIS or RAS system in a new system that is much stronger then the RIS and RAS systems described here.
