Monstrum 4-Slot 45 Degree Picatinny Mount
The Montrum 45 Degree Offset Picatinny Rail Mount is built for modular attachment of optics or accessories to your Picatinny mounting platform.

This is a simple yet effective canted mount. Fits all my different sights and red dots. Monstrum is known for their good materials!

If you want side mount a back-up red dot, etc., this is the ticket. I have several Monstrum risers. No issues with any of them. Solid and well made.

I got these, and yes they function like a picatinny rail. Seem well built. I put them on 3 firearms. 1st 2 firearms I mounted iron sights. Able to sight in and zero, with some somewhat big adjustments to iron sights already zeroed to that firearm. Placement of sights was at exact same opposing lengths as they were previously mounted on top rail. Mounting them at the 45cant on these I had to adjust windage (expected) and elevation (unexpected). I began to question the precision albeit there obviously might be miniature differences in cant due to variable tightness of each rail mounted. On the 3rd firearm I mounted this on, I mounted an optic previously zeroed for a top mount onto the 45° canted rail. Attempting to zero or confirm zero resulted in not even hitting paper (14"x20" target). I made several adjustments to optic in all directions in an attempt to hit paper with no luck, ensuring that i accounted for previous adjustments of opposing direction. At first I thought maybe optic failed to hold zero. Next range visit I'm going to remount optic to top and confirm if zeroed. If it is, then I know it's a machining issue on the rail. If it isn't then it'll likely be the optic. Most of the 45 canted rails are ideally and commonly used for mounting sights. Iron sights are more forgiving in adjustment than optics. So precision machining in cant and dimensions are necessary for rails like these. If anyone has any feedback regarding my thoughts, leave your own review and I'll be checking back after my next range visit to read comments and update this review as necessary.Update, it was the optic that was bad.

This 45° side mount was exactly what I needed. It fit great and worked for what I needed. It is a quality mount at a reasonable price. I would recommend.

Was better than expected for the price. Thick metal with a nice finish. Used to mount back-up sights on AR rail with a thermal scope. Didn't extend far enough from rail to mount behind scope so both had to be mounted on rail in front of scope. Should not be an issue with regular profile scopes. Pleased with purchase.
