CZ Conversion Kit 22 LR 7 8 Barrel Fits CZ Scorpion EVO S1 10 Rounds 1 Magazine 91614 UPC 884400090133
Product Description
The CZ-USA® .22 LR Conversion Kit for the CZ Scorpion EVO 3 S1 (SKU: 91614 / UPC: 884400090133) is an authentic, Czech-manufactured factory original caliber conversion system designed to transform your 9x19mm sub-gun into an economical, ultra-low-recoil rimfire training platform. Engineered directly by Česká zbrojovka to maintain the exact ergonomics, trigger control, and optic sightlines of your defensive or competition Scorpion, this adapter kit allows high-volume marksmanship practice, tactical transition drills, and introductory training at a fraction of the cost of centerfire 9mm ammunition.
Precision-engineered to drop directly into standard CZ Scorpion EVO 3 S1 receivers, the 91614 system utilizes a 7.8-inch precision-rifled steel barrel liner insert that seats into the host 9mm barrel assembly. Driven by a dedicated direct-blowback bolt assembly paired with a factory-tuned recoil spring, the system cycles high-velocity .22 LR rounds with smooth consistency. A hardened steel extractor and precision-aligned ejector guarantee positive spent-casing clearance without stressing or modifying the factory upper receiver clamshell.
The conversion kit includes a purpose-built magazine well adapter block and one factory OEM 10-round polymer magazine engineered specifically for .22 Long Rifle feed geometry. By swapping the central bolt and barrel carrier without changing serialized lower components, shooters retain their custom triggers, handguards, optics, and weaponlights while enjoying whisper-quiet suppressed operation or high-speed steel challenge training.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct drop-in fitment for factory CZ Scorpion EVO 3 S1 Pistol and SBR configurations equipped with the standard 7.72" / 7.8" 9mm barrel. CRITICAL: Will NOT fit the CZ Scorpion EVO 3 S2 Micro (4.1" barrel) due to excessive liner length, and not recommended for 16.2" Carbines. Requires high-velocity .22 LR ammunition (1200+ FPS, such as CCI Mini-Mag) for optimal slide cycling during initial break-in.
- Ensure the host Scorpion is completely clear, magazine removed, and chamber visually and physically verified empty.
- Push out the lower receiver takedown pin, pivot the lower trigger case downward, and slide the factory 9mm heavy bolt assembly out of the rear of the receiver.
- Slide the CZ 7.8" .22 LR barrel liner insert straight into the factory 9mm barrel bore from the rear until the collar seats fully against the barrel breech face.
- Insert the dedicated .22 LR conversion bolt and recoil spring assembly into the receiver tracks, ensuring proper alignment with the cocking handle.
- Reattach the lower trigger housing, lock the takedown pin, insert the included 10-round .22 LR magazine, and manually function test the bolt stroke and dry-fire reset before live-fire staging.
