CZ Scorpion Adapter & Tube Kit - Precision Fit Upgrade for Enhanced Performance

The CZ Scorpion Adapter & Tube Kit is a precision-engineered upgrade that opens up your Scorpion Evo 3 S1 pistol to the full ecosystem of AR-platform arm braces and buffer tube accessories. If you're looking to customize your Scorpion platform with aftermarket stabilizing features, this kit provides the mechanical foundation to do it right. The adapter uses 6061 T6 aluminum construction with flat black anodizing for durability and a professional appearance.

The kit includes both an adapter and a buffer tube manufactured by KAK Industries, engineered specifically for clean fitment on your Scorpion. The adapter threads are standard 1-3/16x16—the same spec as AR-15 buffer tubes—so you're not locked into proprietary solutions. If you decide to run a different buffer tube down the road, the adapter includes two threaded alignment holes (10x32) that accommodate tubes using a notch-indexed design, allowing you to secure your choice of tube with a standard 3/16 half dog socket set screw for repeatable positioning.

This is a mechanical modification that changes your firearm's configuration. CZ USA recommends gunsmith installation to ensure proper fitment, alignment, and function. Whether you're building a more compact Scorpion setup or simply want the versatility of swapping accessories, this adapter kit is the starting point for serious customization.
