HB Industries
Press-fit adapter that converts the Scorpion's proprietary trunnion into a universal 1913 Picatinny rear interface.
The factory Scorpion EVO 3 ships with a proprietary side-folding stock or brace housing that does not accept any aftermarket stock. The HB Industries 1913 Adapter swaps that housing for a low-profile billet aluminum block that ends in a standard 1913 Picatinny rear rail. From there any 1913-interface stock or brace bolts on, including the SBA3, Tailhook MOD2, Strike Industries FSA, Magpul SL-K, and folding stocks like the Sig MCX folder.
Construction is machined 6061-T6 aluminum hardcoat anodized to MIL-A-8625 Type 3, and the adapter weighs 4 oz. Install is press-fit using the same dovetail the factory folding housing rides on, so there are no set screws and no permanent modification to the upper receiver. A rubber mallet or deadblow gets the factory housing off; the HBI adapter taps in the same way.
This adapter is for the CZ Scorpion EVO 3 S1 and S2 pistol and carbine. EVO 3+ owners need HBI's dedicated EVO 3+ adapter instead, since the trunnion geometry changed on the new model. Pair the adapter with any 1913 brace or stock to finish the build.
Add the HB Industries CZ Scorpion EVO 3 1913 Stock/Brace Adapter to your build and see how it enhances your platform.
