The CZ 455 FS Thumbhole (Forend Style thumbhole) was the premium thumbhole configuration in the CZ 455 line — a wide-forend laminate thumbhole stock with the 455 action before the 457 superseded the platform. Discontinued when the 457 AT-One assumed the thumbhole market position. Sought by collectors who prefer the 455 barrel thread standard or who found the 455 FS Thumbhole at favorable used pricing. Type: Rifle Action: Bolt-Action Caliber: 22 LR Capacity: 5 Year introduced: 2012, Czech Republic Weight: 116.8 oz Overall length: 41" Status: Discontinued Intended use: target, bench, collector
