Model and measurements described in the picture. Bought it at All Shooters Tactical, they installed it on the rifle. Didn’t fit properly immediately but that’s all they had in the store so they installed it backwards to get proper eye relief. Could not hit the broad side of a barn with the rifle so I took it back after firing less than 10 rounds. They refused to take it back stating that if they took it back, it was a “used” item. As you can see, it’s brand new. Not a single scratch. Needless to say, I’ll never go back to All Shooters. My loss your gain. can meet at the Buc-ee’s or Bass Pro shop in World Golf Village.
