The factory stock on the ASG CZ Scorpion EVO AEG gets the job done, but it severely limits your setup choices when running modern high-rise optics or full-face protection. Upgrading to sleek, minimalist 1913 picatinny stocks usually hits a wall due to the proprietary rear receiver geometry of the EVO platform.

Engineered by PTS®, the E9-1913 Stock Adapter converts your ASG CZ Scorpion EVO AEG receiver endplate into a versatile 1913 picatinny mounting interface. Molded from the same high-impact enhanced polymer used in the PTS EP component series, it weighs a minimal 30 grams while standing up to aggressive field handling. Featuring 5 full rail slots, it grants the elevation control needed to align your stock height perfectly with iron sights, low-profile red dots, or tall optical risers.

Key Features & Technical Highlights

• Universall 1913 Rail Interface: Replaces the factory stock attachment with a standardized picatinny rail, unlocking compatibility with almost any 1913-based folding stock or brace on the market.
• 5-Slot Elevation Adjustment: Multi-slot rail surface lets you mount your stock higher or lower along the receiver tail, tailoring your cheek weld to tall optic risers or low-profile sights.
• PTS Enhanced Polymer Build: Constructed from heavy-duty reinforced polymer engineered to withstand heavy side-loads, twists, and impacts without adding unwanted weight.
• Ultralight 30g Profile: Keeps your setup nimble, preserving the sharp handling dynamics that make the Scorpion EVO a CQB staple.
• Direct Drop-In Fitment: Precision-molded specifically for the ASG CZ Scorpion EVO AEG receiver—no filing or modification required.
