Heckler & Koch have introduces a new Faceshield compatible folding stock for the G36/HK169/UMP. The design incorporates a pronounced curve in order to fit underneath helmet ballistic faceshields and is also compatible with protective masks.
It folds out of the way (left or right) with a push of a release button but can be put back into the extended position without having to push the release button. The stock can be extended for length of pull with four positions.
The only Riot stock that you can shoot in a collapsed position, and manipulate the weapon ambi.
Looks simple, but way better than all the other Stocks bevor by FAB, B&T or FN-H for many platforms.
This is one of those “no duh” solutions you can’t believe no one has brought to market until now.
