The Montrum 90 Degree Offset Picatinny Rail Mount is built for modular attachment of optics or accessories to your Picatinny mounting platform.
The 90 degree offset design allows for the mounting of a secondary sighting system or for more flexibility in accessory placement. Mount a magnification scope up top for medium range shooting and a red dot at a 90 degree angle for close quarter combat. Or mount your flashlight to the side without your front grip obstructing the flashlight beam.
The Picatinny rail section is 4 slots in length and will accommodate all standard Picatinny accessories, red dots, or optics.
All Monstrum rail and mount accessories come with a lifetime guarantee

I have used Monstrum rings and rails on several builds and they have always been of great quality, this one is no different. Finish is great, there are no burrs on the machined surfaces and it’s stayed on tight for several night hunts and the ride on the 4 wheeler in and out of the woods.

I have several other Montrum mounts and they are all good quality for the money spent.

I set up my rifle for my own personal use. I actually don't like any optic set over the Irons on one them, so I have this attached to the side rail- going up 90, so it's just about 1 inch to the left of my Irons and I've got that Zero's out to 100 yards. I'd use this again and would recommend it to anyone who thinks it would be useful to getting a unique set up.

I used this as a base for a canted red dot on a Mini 14. I tried a variety of 30 to 45 degree canted pic rails but none of them fit with my particular set up and scope. This works great for me. I've put about 200 rounds through my Mini 40 with a pistol red dot mounted on this rail and it hasn't lost zero yet.

It is exactly as advertised and works great. One very minor complaint is the low profile part of the mount. If it was 1/2 millimeter thinner it would be my second favorite mount. Im hoping monstrum starts making an affordable 35 degree mount that are slightly lower profile, because after buying this 90 degree rail id trust it with holding zero on an optic. 4.5/5 stars, would recommend to people who dont need the lowest profile possible.
