May be to long for some scope and ring combinations - Evolution Gun Works HD Picatinny Scope Mount, Howa

Used this rail to mount a Viper Crossfire II 6-18 x 44 with medium vortex viper rings on a Howa 1500 short action. The rail mounted and fit to the action perfectly. This rail does extend out beyond the front most mounting holes of the action. This extended bit of rail prevented my from sliding the scope back far enough to obtain proper eye relief. The rail makes contact with the objective lens. I did not measure but I think extra tall rings may be needed to get over the rail. I intend to order a better scope to mount on this gun and may cut the excess off of the rail if needed at that time.
