Hawke 50mm scope shade - Hawke Sport Optics Sunshade

Purchased this sun shade for a Hawke 4-16X50AO scope mounted on a CZ457/.22WMR with heavy varmint barrel, the scope is mounted on a Bscar 25MOA/extended/extra high pica tinny rail(in order to clear the new style 60 degree bolt throw from the rear scope ring), the scope sits in Leopold 1" "high" (1/2" from bottom of saddle to top of rail) scope rings. It fits fine, I have 1/4" clearance under the tip of the sunshade from the barrel. When you scope this CZ457, watch your bolt lift to rear scope ring clearance.
