Description
Got a rifle or pistol-caliber build with a vertical Picatinny rail on the back of the receiver but no way to run a real stock? That's exactly what the Midwest Industries MI-STAP-LWS was built for. It's a stock tube and lightweight stock combo that clamps onto a 1913 rail, giving you a solid, fixed shouldering point on platforms that were never designed around a buffer tube. Think AKs, CZ Scorpions, and similar setups where you want a clean cheek weld without adding a bunch of bulk.
What Sets the MI-STAP-LWS Apart
Midwest kept this one lean. The beam is machined from hard coat anodized 6061 aluminum and features a skeletonized modular body, so you shave weight without giving up rigidity. The whole assembly runs right around 10 oz and adds about 8.25 inches to your overall length, which keeps things compact and balanced. A steel clamp does the heavy lifting at the rail interface, locking the stock down tight so there's no wobble once it's torqued to spec.
Sling Options and the Minimalist Butt Plate
The stock ships with an aluminum minimalistic butt plate (the MI-STAP-CSP, at 3.75 inches tall) that keeps the profile trim against your shoulder. Sling setup is flexible too, with three anti-rotation QD swivel sockets worked into the body so you can mount up left, right, or straight back depending on how you carry. It's the kind of thoughtful detail Midwest is known for.
Fitment You Should Know
Installation is straightforward and most folks have it mounted in a few minutes. One important thing to keep in mind: this is the fixed, non-folding version, and it's meant for firearms that do not use a buffer assembly. As long as your receiver has a vertical 1913 Picatinny rail on the rear, you're in business. Built 100% in the USA, it carries the fit and finish you'd expect from Midwest Industries gear.

Frequently Asked Questions
What kind of firearm does the MI-STAP-LWS fit?
It mounts to any firearm with a vertical 1913 Picatinny rail on the rear of the receiver, which makes it popular for AKs, CZ Scorpions, and similar pistol-caliber platforms. As long as that rear rail is there, the steel clamp locks it down solidly. It is not designed for firearms that use a traditional buffer assembly.
Is this the folding version of the Midwest Industries stock tube?
No, the MI-STAP-LWS is the fixed, non-folding version. If you want a side-folding option, that is a separate model (the MI-STAP-SF-LWS). This one gives you a rock-solid, permanent shouldering point without any moving hinge.
How much weight and length does this stock add?
The complete assembly comes in right around 10 oz, so it stays true to its lightweight name. Deployed, it adds about 8.25 inches to your overall length, keeping the setup compact and well balanced. The skeletonized aluminum beam is what keeps the weight down while holding its rigidity.
Can I run a sling with the MI-STAP-LWS?
Absolutely. The body has three anti-rotation QD swivel sockets built right in, so you can attach a QD sling on the left side, right side, or straight to the rear. That flexibility lets you set it up however matches your carry style and shooting stance.
