The SB Tactical BTFA Buffer Tube Folding Adapter brings folding capability to firearms that use a standard buffer tube receptacle. It is built for shooters who want a more compact overall length for transport, storage, or maneuvering in tight spaces without giving up a full-size buffer tube setup. The adapter installs between the receiver and the buffer tube, letting the stock or brace fold to one side. Keep in mind this part is not made to work with AR platforms, so it suits non-AR designs that accept a threaded buffer tube. For other rifle hardware, see our rifle parts selection.
The BTFA features a low-profile design that keeps the folding mechanism close to the receiver, so it adds minimal bulk to the rear of the firearm. It is reversible, meaning you can configure it to fold either left or right depending on your preference and how you carry or store the firearm. The folding action locks in place, holding the stock securely once deployed for shooting. SB Tactical machines the adapter from 6061 aluminum with a Type 3 hard-anodized matte finish, which resists wear and corrosion through repeated cycling. It is designed to mate with all standard buffer tube receptacles, giving it broad fitment across compatible non-AR firearm platforms. The hardware ships ready to install on a threaded buffer tube interface.
A folding adapter earns its keep when overall length matters. Shooters transporting a firearm in a shorter case, storing it in a discreet bag, or working through doorways and vehicles benefit from being able to fold the stock to the side. The locking mechanism returns the firearm to a solid shooting platform when extended. Pair the BTFA with a quality tactical sling and the right carry solution from our range gear bags to round out a compact, transport-friendly build.
