AK Folding Stock Hinge and Triangle Stock by Circle 10 AK (1)

Circle 10 AK has just released two new AK products – AK Push Button 2-Bolt Folding Hinge and AK 2-Bolt Triangle Stock. Both of these accessories use 10-32 2-bolt mounting system. Let’s take a quick look at each of these parts separately.

AK Push Button 2-Bolt Folding Hinge

The hinge is compatible with 2-bolt stock adapters that are tapped to take 10-32 screws. Such stock adapters are made by ACE, Krebs Custom and Stormwerks. In order to install the hinge, you will need to align its two holes with the holes on one of the mentioned stock adapters and fasten it in place. Probably adding some sort of thread locking compound will be a good idea, too.

According to Circle 10 AK, unlike other folding mechanisms that rely on spring tension to lock and are normally stiff, their hinge utilizes a push-button mechanism which makes it easy to operate and at the same time provides a secure lockup.

This stock hinge comes with all the hardware necessary to mount it on the stock adapters. The MSRP of this product is $54.95.

AK 2-Bolt Triangle Stock

This triangular stock is compatible with 10-32 2-bolt side folding adapters. It is deliberately designed to be a bit shorter so that when used with the side folding mechanism the whole assembly won’t have an excessively long length of pull.

    Does anyone make a hinge that can be installed forward of a fixed stock to allow it to fold?

    Someone did a few years ago and marketed it as making your wood stock a folder but it's since been discontinued.

    Will it work with my fixed stock AK? That's all I really care about.
