Questions & Answers
Will this work with the Trijicon RMR Sight 13 with RM33 Picatinny rail mount? Expert Answer

Yes. The TANDEMKROSS Shadow Picatinny Rail will secure to a Ruger MK II/III/IV and allow for any optic with a picatinny rail mount to fit.

If I use this on my Mark IV Hunter with a Vortex Venom red dot, will I be able to view my front sight through the groove with the Venom mounted? Expert Answer

It is unlikely you will be able to see the front sight. The sight will most likely be blocked by the base of the red dot sight.

Ruger MKII/45 scope base by NCHunter, October 16, 2018
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, 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.
