AR-15s are easily American most popular rifles, however, one of the biggest drawbacks of these rifles is that they can't have a folding stock, since the buffer tube extended into the stock.

Well, with the Sylvan Arms AR Folding Stock Adapter you can solve this problem, and carry your AR platform rifle with the stock folded. The Sylvan Arms AR Folding Stock Adapter is specifically designed for direct impingement rifles like the AR platform and is compatible with all standard bolt carrier groups and buffer systems.

The adapter is installed between the receiver and the buffer tube, allowing you to fold your stock to the side with the buffer tube. However, you can't fire the gun without extending the stock. This folding stock adapter allows you to easily carry your rifle in confined spaces like a car and store them away more easily.

The Sylvan Arms AR Folding Stock Adapter is very lightweight and durable. It is made from durable 7075 billet aluminum and has a hard coat anodized finish. It also adds 2 inches to your rifle's length of pull.
