I've just returned from the SWAT Roundup in Orlando. Reed Knight invited me over to the plant for the cooks tour and I've got to tell you that he has set up one of the finest production facilities I've ever seen. The MWS is in full production along with his new Stoner, my favorite, and his 308 M-16 on steroids.
One great advantage to the design is the increased surface area of the forstock which affords a significant increase in cooling capacity. The multi mount capability is not for everyone but for those that find comfort in mounting various sighting and lighting aids it does allow great flexibility.
