Midwest Industries Mitrisffde Triangle Side Folding Stock Fde 6061 Alumn

The Midwest Industries Triangle Side Folding Stock in FDE brings heavy-duty, space-saving functionality to your AR-platform rifle. This side-folding stock is built from hard-coat anodized 6061 aluminum with a heat-treated steel folding mechanism, giving you a compact package when space is tight without sacrificing structural integrity. Whether you're running a home-defense carbine, setting up a truck gun, or building a compact field rifle, this stock delivers the rigidity and lockup reliability shooters depend on.

The mechanism is purpose-built: a full-length locking lug, 4140 steel clamp with generous surface contact, and positive engagement in both deployed and folded positions ensure zero wobble when shouldered. You get five QD sling attachment points for maximum versatility—run it with your preferred sling setup without drilling or modifying. The Midwest-made polymer cheek piece and rubber butt pad add comfort during extended shooting sessions, while the FDE finish blends aesthetically with modern tactical builds.

Configuration flexibility is a standout. The stock can be set up for right or left folding, so it adapts to your setup, your hand preference, or tight spaces (vehicle, doorway, or heavy brush). When extended, it adds 9.25 inches to your rifle's overall length; folded, just 0.75 inches, making it ideal for vehicles, aircraft, or transport cases. At 19 ounces, it's substantial enough to feel solid without bloating your rifle's weight budget. Steel components are mag phosphate finished for corrosion resistance. Backed by Midwest Industries' lifetime warranty and proudly made in the USA.
