HB Industries CZ Scorpion EVO 3 Magpul Zhukov-S Stock

The Magpul Zhukov-S is the most popular non-folding aftermarket stock on the CZ Scorpion, but the standard Magpul AK trunnion adapter stacks up over an inch and a half of dead length behind the receiver. HB Industries' direct-mount adapter integrates the Zhukov-S straight to the Scorpion trunnion, removing the AK trunnion adapter that ships with the Magpul stock. The result is a stock assembly that sits 1.7 inches closer to the receiver than the universal AK setup, which preserves length-of-pull on a rifle-config Scorpion and lets SBR builds run a shorter LOP without rear overhang.

Construction is billet 6061-T6 aluminum hardcoat anodized to MIL-A-8625 Type 3, and the adapter press-fits to the Scorpion trunnion using the factory dovetail with no set screws. Install is reversible. HBI sells the kit with the Zhukov-S stock at $192, or as adapter only at a lower price for owners who already have a Zhukov-S. The Zhukov-S itself adjusts through five LOP positions, folds left, locks open with positive engagement, and accepts QD swivels and rubber buttpads.

Critical: this is a stock, not a brace, so it must be installed on a registered SBR or rifle-config Scorpion. Pistol-config Scorpions need a brace solution like the SB Tactical SBT EVO or the Tailhook MOD2 on the HBI 1913 adapter instead.
