Any news about this? Is it still being worked on or did you decide to cancel the project? Any chance you guys are working on a fore end/hand guard for the HK416/MR223 line of rifles? That would be an excellent addition to your line up. I would for sure purchase if its like your G3 or SL8/G36. Also you make the best Optic Mounts in my opinion, going to be purchasing a sp3001.
