I finally found a practical use for the “pre-ban” Colt HBAR flat top I purchased in 1996. I saw a lot of coyotes while deer hunting up on the ridge behind my house last month and I'm going to thin them out a little. In the past I've shot it with the carry handle sights so I know it's a tack driver. Unfortunately my eyes no longer work that well so I'm mounting a Leupold 3.5-10x50mm on it. Has anyone done this? If so, how high is your scope off of the picatinny rail and how visible is the front sight on the scope’s low power? I’m thinking of using a Millett M4 extended riser (+0.625”) and high (+0.75”) or super high (+1.00”) rings. Any input or advice would be welcome. Thanks in advance.
