The Midwest Industries Mitrisf triangle side folding stock brings serious capability to shooters who need compact handling without sacrificing stability. This side-folding rifle stock combines a steel folding mechanism with a 6061 aluminum body, engineered to collapse the gun's profile for transport or tight-quarters work while locking rock-solid in the firing position. Whether you're running a short-barreled rifle, navigating confined spaces, or building a truck gun, a side folder lets you keep the firearm ready without the length penalty of an extended stock.

The folding mechanism itself is the heart of this design: a 4140 heat-treated steel action with a full-length locking lug distributes force evenly and resists flex under recoil. The steel clamp grips with a large surface area for secure engagement in both deployed and folded positions. Mag phosphate finish on the steel parts handles hard use without fuss. Five QD sling attachment points give you options for how you want to sling the rifle—critical when space is at a premium.

Comfort matters, even on a tactical stock. The cheek piece and butt pad are Midwest's own polymer and rubber construction, angled and dimensioned for a consistent sight picture and softer shoulder impulse. The stock can be configured to fold right or left, so it works whether you're a righty or southpaw. At just under 20 ounces fully assembled, it won't bloat your gun's weight budget. Fold it down and you're adding less than an inch to overall length; extend it and you gain nearly 9.25 inches of LOP and leverage. Made in the USA and backed by Midwest's lifetime warranty.
