Monstrum 2X Flip-to-Side Forward Magnifier | Compatible with LPVO, Prism Scopes, Fixed, and Variable Magnification SFP and FFP Optics

Works well with ANYTHING. Prism, holographic, red dot. Worth getting a few of them. But you do NEED to zero with it on whatever you put it on. Zero main optics first, then zero the 2x flip. It will need to be zeroed separately, for accuracy

Great product and service!

This is a great idea as I don't like the rear mounted style magnifiers as they are way too close and have a small exit pupil. At Best they are difficult to use. This on the other hand is some excellent engineering and aside from the weight, it works amazingly well. I find it much more versatile, and excellent price and with the addition of a QD mounting lever, this would make it even more versatile. I have used this in front of LPVOs and prism optics. If the casing could be slightly lightened up and the QD lever would make it a game changer. Thank you!

I have this magnifier mounted in front of a primary arms slx 1x micro prism, mounted right up at the forward end of the upper receiver. Tight fit with a magpul mbus sight, 1x micro prism, and this magnifer; but it works and there is some space between micro prism and magnifier. It works as intended and I didn't have to use the spacers to change the mounting height as the primary arms micro prism is also at 1.5" height. I see a review complaining about eye relief and another about field of view. The one complaining about eye relief used this magnifier incorrectly, it goes in front of your optic not behind like a traditional magnifer. I have no issues with eye relief, its the same with or without the magnifier, no change in eye / head position. As for field of view, there is a reduction. It's similar to zooming in with a scope where there is a reduction in field of view. I tried a monstrum ghost ultracompakt 3X micro magnifier, but it didn't work out for me. Could not get proper eye relief or sight picture with any amount of adjusting the diopter. Might work out better behind a red dot or holographic sight. It did work when I mounted it in front of the optic, but I had to mount it to the rail which is not ideal. Returned and bought this 2x forward mount magnifier. For those looking at this 2x forward magnifier hoping that it will magnify the reticle (dot, crosshair, etc..), it will not. It can only magnify what it see's and since it mounts in front of the optic, it doesn't see the optic and can't magnify it.

I have a Swampfox Blade prism optic with 1x (so no) magnification and I've been wanting a way to add magnification for the rare longer distance shot I might take with the rifle that optic is mounted so I was intrigued when I stumbled on this forward magnifier. This magnifier seems to be made of quality materials and has a nice finish, the mount fits solidly and the screws for mounting felt strong (I didn't feel like they were at the point of stripping and didn't fear really tightening them down). It did take a bit to zero it in, there was a big difference between my optic zero and the zero with the magnifier in use but once zeroed it held nicely and worked great. I love the swing mount, no button to push when swinging out or back in, just swing it. It holds firmly yet doesn't take a lot of force to swing it and feels really solid with no wiggle or play in the hinge/pivot. When I bought my prism optic, I didn't want one with a fixed 3x or 5x magnification, for normal use I prefer no magnification but it is really nice to be able to add the 2x now and then. I'm really happy with this magnifier and I do recommend it. I'm probably going to buy another one for use with the LPVO I have on another rifle so I can bump it's 1-6x out to a 1-12x when needed.

Great product, exactly as advertised, installed and sighted in quick and easy, clear glass, lot of light. If monstrum was to ever come out with a 3X or 4X version I would definitely be getting one

I'll wait for someone else to do it better. Pro: First ones to figure it out. Thank you! It really works and that's pretty amazing. Feels like a brick. Clear glass. Con: Nobs feel tacked on. Enormous for seemingly no reason. They don't even care to protect the lenses in the packaging, so don't expect lens caps. 8oz is pretty heavy for 2x these days. Deal killer: Super tall mounting bracket. If they used a different design like PA or Vortex they could have shaved some weight and put the magnifier at a reasonable elevation.

Received opened package with scratches on outside of optic and smudges along the scope and glass. Updated review: Smudges came off easy. The magnifier is actually pretty nice. I compared to sigs Romeo and Juliet combo which had terrible eye relief. This magnifier did not have that issue. This magnifier has good eye relief. Doesn’t line up perfectly with my trijicon mro but it lines up well enough to be used accurately. If the package came new and sealed I would give it 5 stars. Just left a bad taste in my mouth having it be opened and clearly used.
