Midwest Industries Picatinny Side Folding Fixed Extruded Stock Black

The Midwest Industries Picatinny Side Folding Fixed Extruded Stock in Black is a purpose-built modular stock system engineered for AR-pattern rifles requiring compact storage, vehicle deployment, or transitional carry. Built around a heavy-duty side-folding mechanism constructed from 4140 heat-treated steel, this stock delivers the rigid support and fast deployment operators demand in confined or dynamic environments without sacrificing structural integrity.

The stock features a full-length locking lug and solid positive lock-up in both extended and folded positions, preventing inadvertent collapse during firing or movement. The steel clamp incorporates large surface engagement to distribute clamping force across the receiver extension, reducing rocking and micro-movement that degrades accuracy. Constructed from hard-coat anodized 6061 aluminum, the stock body combines minimal weight at 1.31 lbs with the corrosion resistance required for extended field operations. The triangular cross-section design maximizes rigidity while maintaining a low profile when folded. Configuration flexibility allows right- or left-folding orientation depending on operator preference and platform design, while five Quick-Detach sling attachment points accommodate tactical slings and support gear mounting.

This stock suits AR-15 and AR-10 platforms where space is constrained—vehicle-mounted weapons, breaching entries, or compact storage in tactical vehicles. The side-folding design keeps the rifle profile minimal while remaining faster to deploy than fixed-length alternatives. Operators valuing modularity, positive lock-up, and lightweight construction will find this Midwest Industries unit compatible with standard mil-spec receiver extensions and suitable for duty, training, or precision applications.

Midwest Industries manufactures precision AR accessories to tight tolerances, and this stock reflects that attention to fit and function—no wobble, no guesswork, no compatibility surprises when installed correctly on a mil-spec or commercial receiver extension.
