I have a S&W M&P15-22lr. I'm replacing the factory quad rail with the factory M-LOC rail. I have a Leupold 2-7x28 rimfire scope. I'd like to find a lightweight, cantilever type, one inch, quick detachable scope mount. I haven't had any luck. They all seem heavy like the ADM QD mount I have on my MK12ish clone. Any ideas?

Thanks, NYH1.
