A3 Industries
The A3 Tactical Triangle folding stock brings practical modularity to your AR platform rifle without the bulk. This 9-inch aluminum folding stock is built for shooters who need a compact package for vehicle storage, tight spaces, or tactical situations where a collapsible profile matters. The rigid aluminum construction keeps things solid and reliable, while the heavy-duty steel hinge mechanisms lock positively in the open position and deploy quickly when you need to fold—no fumbling, no guesswork.
Real-world performance means comfort and control when it counts. The injection-molded rubber butt-pad absorbs recoil and seats firmly into your shoulder, while the textured cheek-rest helps you find a consistent sight picture without slipping. Two quick-disconnect sling mounts at the front of the stock give you flexible attachment options for your preferred sling setup, whether you're hunting, running drills at the range, or training for duty work.
Built from fiber-reinforced polymer and machined aluminum, this stock resists impact and handles field use without complaint. The design is straightforward—no levers to break, no springs to rattle loose. If you're building or upgrading an AR and want the advantages of a folding stock without sacrificing rigidity or ergonomics, the Triangle is a solid, no-nonsense choice.
