AR-15 KCI (BETA STYLE) 100 ROUND HIGH CAPACITY DRUM MAGAZINE 556

SGM Tactical (manufactured by KCI) Beta C-Mag style 100 round drum for the AR-15. These are a clone of the Beta Mag, and a good one at that. These are manufactured in Korea for SGMT by KCI, and they have a good history with their extended Glock magazines and AR-15 drums. These SGMT 100rd drums are nearly identical to the C-Mag, and function well. They have the same limitations that the Beta does... keep it reasonably clean and lubed up with graphite. Beta or KCI, if you take these two suggestions to heart you will have a good, functional drum. These drums are functional, durable, and cost far less than the Beta mag. Kit comes with pouch, loader and graphite lube. Please don't forget to leave a  SGM / KCI 100 round drum review for this product after your purchase! Functions: AR15 rifles and variants that function with GI spec AR-15 magazines.
