Strike Industries Stock Adapter Back Plate for CZ Scorpion EVO 3 Red SI CEVO SA QD RED SI CEVO SA QD UPC 793811763430
Product Description
The Strike Industries® Stock Adapter Back Plate for CZ Scorpion® EVO 3 in Red (SKU: SI-CEVO-SA-QD-RED / UPC: 793811763430) converts the factory CZ Scorpion rear receiver dovetail into an ultra-rigid 1913 Picatinny interface while adding a striking anodized red accent to your custom build. Engineered to replace standard factory polymer end caps, this CNC-machined adapter expands tactical modularity by allowing immediate mounting of Picatinny-compatible folding stocks, stabilizing arm braces, or sling systems while preserving the streamlined contours and beveled aesthetics of the host receiver.
Precision-machined from aerospace-grade 6061-T6 billet aluminum, the adapter delivers immense shear resistance and torsional rigidity under heavy 9mm blowback cycling. The metal chassis is finished with an abrasion-resistant red anodized coating that defends against field corrosion, carbon buildup, and aggressive chemical cleaning solvents. By utilizing solid billet aluminum in place of factory-style polymer housings, the adapter eliminates receiver flex and prevents mechanical slippage or loosening when applying aggressive shoulder pressure.
Designed for rapid tactical deployment, this back plate integrates a heavy-duty push-button Quick Detach (QD) sling swivel socket directly beneath the Picatinny rail section, providing an ideal low-profile attachment point for one-point and two-point tactical slings. The rear Picatinny track offers vertical adjustability, allowing operators to clamp stocks or braces at various heights to dial in exact optical eye relief and cheek weld alignment. The direct slide-in architecture utilizes the CZ factory spring detent for a seamless, rock-solid lockup without adding unnecessary receiver bulk.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct slide-on fitment for all CZ Scorpion EVO 3 models, including EVO 3 S1 Pistol, EVO 3 S1 Carbine, EVO 3 S2 Micro, and CZ Scorpion 3+ (Plus) variants. Compatible with all standard 1913 Picatinny clamping stocks and pistol stabilizing braces. CRITICAL: Attaching a mechanical shoulder stock to a CZ Scorpion pistol with a barrel under 16 inches constitutes the creation of a Short-Barreled Rifle (SBR) under the National Firearms Act (NFA) and requires an approved ATF Form 1 tax stamp. Ensure the factory detent button fully protrudes and snaps into the central locking recess of the adapter plate prior to mounting any 1913 stocks or accessories. Clamp cross-bolt torque for attached 1913 stocks should be torqued to manufacturer specifications (typically 25 to 35 in-lbs).
- Ensure the host CZ Scorpion EVO is completely cleared, magazine removed, bolt locked rearward, and the chamber visually and physically confirmed empty.
- Depress the factory receiver end-plate detent button located at the rear bottom of the receiver housing using an armorer punch or hex tool, then slide the factory polymer end cap downward to remove it.
- Inspect and clean the host receiver's dual vertical dovetail channels with an armorer brush and light solvent, removing any carbon accumulation or debris.
- Align the Strike Industries 6061-T6 red anodized adapter with the receiver dovetail tracks and slide the plate upward until the factory spring-loaded detent snaps fully and positively into the adapter's locking recess.
- Verify zero vertical or lateral play in the back plate, attach your selected 1913 Picatinny stock or stabilizing brace to the rear rail, and test the lower QD sling socket retention before live-fire staging.
