Hey folks, this optic is more for an ar, I purchased it recently, mounted it and also installed an elftmann trigger. I did not install the spacer plate and set screws in the drop in trigger which caused it to double tap. After a few double taps, the RO was not happy so I left the range, I also learned that 6x is not really enough magnification for shooting groups at 100yds, so my loss is your gain. I'd like to get 250$ as it cost me over 350$, Scope is like new and glass is quite beautiful. Thanks,John
