Bramm the Viper is my main scope 10x44 ,only thing is the paint on the flip ups is not very good , i dont think it as any base coat ,or etching paint on.I took mine off and featherd them with wet and dry paper .Then i re sprayed them with -Holts dupli color auto spray Acrylic formulation on the top reads L146 Satin Black. .Made a cracking job of the flip ups. The black slip over cover rubs the high spots on the scope. [ Dont use it.]
