Full description


The 5KU AK Russian Side Folding Buttstock is designed for AK models that feature the standard Side-Folding Triangle Skeleton Stock, and will completely replace the back of the Rifle with a much more comfortable and ergonomic design. The Stock connects to the back of the Receiver via a single pin; if your AK matches this then it should fit.

The Stock features an Adjustable Rubber Cheek Pad which can be raised/lowered by loosening the Allen Screws that hold it in place and manually moving it. The Stock also offers a comfortable Rubber Butt Pad which will provide grip in the shoulder, and can be adjusted for height to suit the user. A large Sling Loop can be found on the Stock to retain or enhance and Sling Setup you may currently be running. The Stock also has a Sliding feature, allowing it to be set to one of many positions, setting the correct length for a specific user. To adjust the length of the Stock, raise the grey flap that is secured by a magnet and press directly down on the middle of this assembly to release the Sliding mechanism.

A spacer is included in the box which is to be used when the Stock is installed on a Gas Blowback AK, just to ensure a perfect fit. If you own an AK replica with a Triangle Side-Folding Stock and you want something a bit more tactical and comfortable, then the 5KU AK Russian Side Folding Buttstock is ideal for you.
