I am currently running the RL-2 5pin dovetail and had misplaced the sight tape that came it. The one I received was significantly smaller in scale, when ordering be aware of this and clarify left or right handed shooter. I'm right hand and was sent left hand sight tape as there is no option to choose either side.
I just purchased and installed the RL 5. I like the features but mine has developed a noise/ vibration in the windage adjustment knob. I have reached out via email and text in the contact us tab on Redline's site but have yet to hear back with a remedy for the issue
Overall, this site looks to be high quality. I just received it and it seems of sound materials, easy to install and has lots of nice features. My only issue, and it is probably my fault, is I read the description like the bottom pin, of the three pin, is a floater. I interpreted that as the top two pins were fixed and the slider adjusts the bottom pin only. Probably my fault for misreading.
I got sent right handed sight tapes because there is no option for lefty’s. I figured they would be interchangeable but no.
