This weaver style base was an easy install on my buckmark. The slide worked as advertised after install. No dragging. Don't overtighten screws as you are screwing into aluminum. Instead, use locktight blue. Would have liked to have seen a rear sight on this base but overall not a big deal as a red dot was installed. I.e. as long as the optics battery dosen't die your gtg.
Pros: Ease of install
Cons: No rear sight
