Aftermarket SCAR retractable stock

by Miles

A small start up company by the name of Otto Arms LLC, appears to be unveiling an MP5 like retractable stock for the SCAR Light platform. I’ve tried getting in touch with them for more information, but haven’t gotten anything about it at this time, so I cannot even speculate on price. The company seems to have just started up in September, and apart from their stock and promotional women on their Facebook and Instagram pages, don’t have any other products or prototypes to show yet. Despite their lack of website infrastructure, their idea for a collapsible stock is certainly interesting, probably one of the few entrepreneurs outside of FN Herstal itself (on thier PDW variant) that is working on a retractable stock.

    I don't understand all the hype about the MP5 style retractables. Between all the AR style stocks and lust for the MCX retractable and now this. They aren't as short as a folder when collapsed vs folded and they aren't as comfortable when extended vs unfolded. Can somebody explain it to me?

      @mig1nc The MP5 is used by all kinds of high speed, low drag Operators.
      Thus, making your gun kinda similar will make you a SAS Navy Seal Delta Force Tier One Operator.
