If you're a rifle enthusiast, you know that buying all the parts and accessories that you need for your weapons can be pricey, especially if you want to purchase good-quality merchandise. However, you don’t have to forego buying accessories because of their high cost. There are certain ones you can make yourself, such as a locking folding stock. If you're handy with tools, you can easily make one, and you'll save money as well.
Understand your rifle. To avoid damaging your weapon, it's crucial that you understand how it functions. For example, M4-style rifles have a buffer spring assembly in the stock, which allows the bolt to uptake another round. If you make the stock in such a way that the buffer cannot move freely, the rifle will be ruined until you find another stock.
Decide on where you want to cut the stock. For stocks that don’t have internal mechanics, you can make the cut almost anywhere. If there are internal mechanics, you'll need to be more careful about where you cut. You'll need to leave room to attach the hinges, which will be more difficult to do if you cut too close to the front of the stock.
Cut the stock. Make a clean cut all the way through. If there are any rough edges, the stock won’t come together smoothly when you extend it.
Bore holes for the hinges. You can either put the hinges on the outside or put them where the two pieces will meet. If you choose the latter option, you'll need to carve out a small piece of the stock so that the hinges will not interfere with the folding mechanism; you can do this with a metal file or a strong router.
Screw on the hinges. Make sure that they're straight, or else your stock will fold awkwardly. A level may help you determine this, depending on your type of rifle.
Attach the locking mechanism. There are a number of ways to do this, although one good way is to use strong magnets. Glue one magnet to the side of the stock and the second one to the side of the weapon in such a way that they'll attach and detach as needed.
