This unique UMP/MP5-style stock is custom designed to use our Modular hinges. This means that now you can use the iconic UMP/MP5-style stock on any firearm that we make a rear adapter for, or most firearms with a rear Picatinny (1913) mount. And, since our hinges can be flipped, this also means that you can Left-fold a UMP/MP5-style stock, something that was never possible before.
Manufactured from durable MJF Polymer with machined reinforcements at the hinge mounting point. Since it can be configured with any of our hinge options, the possibilities are endless.
NOTE: if your firearm does not have a rear Picatinny rail, you must use one of our 2-bolt rear adapters to mount the stock.
