BudsGunShop.com - Scope mount

no rings and it has a built in 11mm dovetail for optics mounting Discontinued 2018 (replaced with 457 Training Rifle). Our incredibly popular Training Rifle has joined the 455 platform. Chambered in .22 LR or .17 HMR, the 455 Training Rifle shares the same popular features of its predecessor – it has the same 24.8” barrel, tangent rear sight (adjustable for distance) and beechwood stock with Schnabel forend.

The biggest difference is the ability to swap the barrel and/or stock, traits that all our 455s possess. An ideal rifle for introducing youth to the shooting sports, the Training Rifle is shipped with a 5-round magazine, but a single-shot adapter and 10-round magazine are available.

******The 455 models feature an integral 11mm dovetail for scope mounting. so you will need 11 mm rings available here https://shop.cz-usa.com/SearchByKeyword?word=11%20mm%20rings
