Folding Stock — Airgun Folding Stocks & Folding Stock Adapters for PCP and CO2 Air Pistols

An airgun folding stock is a shoulder stock that mounts to the rear of an air pistol or compact airgun and folds flat along the receiver when not in use. Deployed, it gives you a third point of contact — shoulder, cheek, grip — which is the single biggest stability upgrade you can make on a pistol-format airgun, especially at distance. Folded, the whole package shortens dramatically for transport, storage, or working in tight quarters. Airgun Capital's folding stock mounts on a standard Picatinny rail, locks with a spring-loaded detent and cross-pin so there is no play at the hinge when deployed, and folds with one hand.

The folding stock itself mounts on a standard Picatinny rail, and most air pistols have no rail at the rear of the gun. The folding stock adapter solves that: a model-specific mount, machined for a particular air pistol, that gives the stock a rigid, repeatable connection point. It also means one folding stock can move between multiple airguns — buy one stock, add an adapter for each platform, and swap in seconds.

If your airgun already has a Picatinny rail at the rear, the folding stock mounts straight on. For air pistols that don't, we're machining model-specific folding stock adapters, and the confirmed list of supported models will be published on this page the day the folding stock launches. If you want your pistol on that list, email support@airguncapital.com with the make and model — customer requests decide which adapters we machine next.

Airgun folding stocks and folding stock adapters sold for legitimate airgun use are airgun accessories — they are not regulated under the National Firearms Act, so there is no tax stamp, no Form 1 or Form 4, and no federal background check to buy one. One important boundary: our folding stocks and adapters are designed and sold for airgun use only. Attaching a shoulder stock to a powder-burning firearm pistol is federally regulated and can create an NFA short-barreled rifle — do not install airgun accessories on firearms. As always, state and local laws vary, and it's the buyer's responsibility to confirm legality at their delivery address.

The folding stock is in final production and launching soon, and the first machining run is a small one. The fastest way to know the moment it goes live is the notify form on this page — leave your email and we'll send a single launch announcement. You can also email support@airguncapital.com and we'll add you to the list directly. In-stock orders ship from Miami with same- or next-business-day dispatch, and that will apply to the folding stock line from day one.
