Most Helpful Positive Review Ruger MKII/45 scope base
High quality. Fit and matched the guns finish perfectly. Scope ring base fit nice and snug in the rail. A bit of a wait to fulfill my order but worth it. Would recommend to anyone wanting to put a scope on your Ruger MKII/45

Great fitment.

by RT, Verified Owner from WI, United States Written on September 28, 2025
Fit the pre-drilled receiver exactly as it should. Screws were pre-treated with LockTite. Shot 500 rounds so far; optics held zero, and nothing loosened up.
Pros:
  • ease of instalation
Cons:
  • More expense than most...but worh it. So it isn't really a Con
Best Used for:
  • Do it yourself
Would recommend: Yes

Nice Fit and Finish

by Max, Verified Owner from CA, United States Written on February 3, 2024
This is pretty much how Ruger should have designed the rail for the Mark series pistols. You can sight through the groove down the center when optics are not installed, it is a little on the tall side though, so you might want to change to a more direct-mount plate once you decide what optic you are going to use (I can't fault the design for that).
Pros:
  • Lightweight
  • Quality
  • co witness
Cons:
  • bore height
Best Used for:
  • Changing out optics frequently
Would recommend: Yes
