A3 Industries
The A3 Industries Triangle Folding Stock is a lightweight, compact stock solution for shooters who need to shrink their rifle's footprint without sacrificing stability or comfort. Built from fiber-reinforced polymer with a rigid Zytel body and machined aluminum components, this 9-inch folding stock combines durability with practical everyday usability—whether you're running a short-barreled rifle (SBR) for tactical work, transport, or cramped shooting positions. The integrated cheek rest and rubber buttpad keep your cheek welded and your shoulder comfortable even during extended sessions.
What makes this stock stand out is the engineering underneath: a heavy-duty steel hinge that locks positively in the open position yet deploys and folds with satisfying speed when you need to collapse the rifle. That's the kind of reliability detail that matters when you're relying on your gun to work the first time, every time. The two QD sling mounts positioned at the front of the stock give you mounting flexibility and fast-adjust options for field use.
If you're building an AR-pattern rifle, sbr, or other platform that accepts this stock, the Triangle folding design balances minimal collapsed length with the rigidity and shooter comfort you can't compromise on. The polymer construction keeps weight down compared to aluminum-heavy alternatives, while the textured surfaces and molded cheek support mean you won't be fighting your gun during aim.
