BT Folder MP5k
Knew what I was getting into when buying this, but I can't seem to find the perfect MP5K stock. This stock comes close. Very comfortable, lightweight, perfect fit with zero wobble anywhere and aesthetically pleasing. I'm 6' and the short stock feels perfect to me personally. Really wish that this came with a QD sling mount though. The fixed swivel is obsolescent. Quite expensive for what amounts to 95% plastic. Friction in the hinge is what keeps the stock folded, and I hope that it doesn't loosen up too much over time. Locking latch is a relatively small amount plastic, looks like it would break off if the gun were accidentally dropped just right. A metal adapter, hinge and locking mechanism, a QD sling mount and maybe a simplistic retention mechanism for the stock when folded would make this a 10/10.
