The perfect Czech mate

I have tried most of the Ace folding stock mechanism since they introduced their very first version (except their new steel model) with absolute satisfaction. I've used it on AR with dedicated .22 conversion kit, varieties of tactical .22's and shotguns. This particular folding mechanism perfectly suited my vintage paratrooper VZ-58 when upgraded to straight stock configuration using AR furniture and high rise optics. The locking mechanism is solid and easy to operate - the perfect replacement of the original metal side folder.

Great Folding Stock Mechanism!!

Lockup on the mechanism is solid with no wiggle. I'm very happy with the solid metal construction of the device it is also priced affordably. The stock stays securely in place when folded up as well. It installs quickly and easily with just two screws.
