Midwest Industries Lightweight Picatinny Stock with Side Folder$178.95
Availability: In Stock
The Midwest Industries Side Folder Picatinny Receiver Extension gives you the compact, deployment-ready handling that matters in tight spaces—vehicles, urban environments, or situations where full length becomes a liability. Built around a mil-spec aluminum stock tube with hard coat anodizing, this side-folding assembly lets you configure left or right orientation to suit your shooting hand and setup, then locks solid in either position thanks to a full-length locking lug and heavy-duty 4140 steel folding mechanism. Whether you're running a dedicated truck gun, preparing a home-defense carbine, or building a compact tactical platform, this receiver extension collapses to just 0.75 inches while adding only 7.375 inches to your firearm's length when extended.
The engineering here is straightforward and uncompromising. A steel clamp with large surface engagement ensures zero rattle and positive lockup every time. The modular design accepts different stock attachments, so you can swap uppers, stocks, or cheek risers without replacing the entire tube. A practical waterproof storage compartment in the tube itself gives you discrete space for cleaning patches, spare batteries, or basic field gear. All steel components are mag phosphate finished for corrosion resistance, and the whole assembly weighs just 13.5 ounces—minimal burden on a carbine build.
Made entirely in the USA, this is the kind of part that rewards quality-focused builders who don't settle for loose assembly or one-size-fits-all solutions. It's built to run and run hard, whether you're testing reliability at the range or counting on your rifle in the field.

Yes. The Midwest Industries side folder is designed to be configured for either right or left folding, so you can orient it to match your shooting hand and installation preference.
The modular design accommodates different stock attachments, but the specific models compatible with your setup depend on the mounting interface and stock tube specifications of your chosen stock. Verify compatibility with your intended stock before purchase.
When extended, this receiver extension adds 7.375 inches to your overall firearm length. In the folded position, it adds only 0.75 inches, giving you significant compactness when space is critical.
This is a receiver extension assembly with the stock tube and folding mechanism. It does not include a finished stock or cheek riser—you'll need to attach a compatible stock of your choice to complete your build.
