Innovative Arms, maker of the Integral Suppressor for the Scorpion, announced their new handguard/heat shield. It is available for preorder and owners of IA-SC9s will get preferential treatment (or so I have been told via phone call with IA). You must register your IA-SC9 before ordering to take advantage of it. The introductory pricing is just that.
This prototype is not the actual hand guard that will be shipping in March. The final product will have a single MLOK slot at the 9 and 3 positions for mounting lights/lasers/etc. The handguard design is pretty ingenious, using the HB Industries charging handle slot for affixing the front end and a single MLOK screw to secure it in the back. The bottom MLOK slots are retained.
