Monstrum Low Profile Picatinny Riser Mount (0.5" H x 5.7" L), for Scopes and Optics

FITS AND WORKS GREAT . NICE QUALITY .

Good quality. Fitment was exact. Installed in seconds. Used it to tie two planes together as one, rather than a riser. Serves the purpose perfectly.

Monstrum Low Profile Picatinny Riser Mount (0.5" H x 5.7" L) Precise, solid, .5" high riser. Just what I needed to bump up my scope height. The riser I received was different than that shown in the product description photos. It did not have the "Monstrum" logo printed on it, (I am Ok with that) and the mounting nuts are hex nuts, tightened with a wrench, not the knurled thumb knobs shown in the pic. I am also Ok with that. This works for my needs. Price seems fair.

Works great to bring up a red dot to get it above the A2 front sight post. I used the "blue" loctite to keep riser secured and has remained tight thru multiple range trips and I beat the bejesus out of my weapons. Monstrum makes good stuff for their discount prices. Good experience and will buy more from this seller.

Easy to install. Works well to raise scope to acceptable level to mate with clip on NVD. Have not encountered any loosening on recoil; however, I used blue loctite and torqued to 45 ft lbs. The weight of the riser is negligible and its construction seems durable. So far very pleased with product.

Works as it should

This is a good product. You should be aware that due to how it is made it does not work with the Vortex mounting systems on my 3x magnifier. If there were a 45 deg bevel machined off the side opposite the attachment screws it would work with Vortex. I think this is more of a vortex issue not the fault of this product. It worked fine with my Holosun Red Dot but that was not what I would be using with this product so I ended up returning it. In short, a well-made solid product that did not work for my particular use case.

It would be better if this product had deeper slots in the thumb nuts. The slots, as they are, are not deep enough to fit any kind of coin or screwdriver in order to really tighten the nuts down. After tightening as much as I could based on finger strength alone, the nuts still came loose after about 20-30 rounds of .308. This meant that the rail could "wiggle" about 1/8" forward or backward - not enough to really make a difference, but still annoying. The solutions are, of course, to either a) loctite the nuts in place or b) use a wrench or something to clamp them down. But both options make it difficult to remove the rail (especially without a tool) if you need/want to. Instead, a deeper slot would allow you to clamp it tight with a coin and also loosen it with a coin, for instance.

Great rail for my setup. I’d recommend for anyone’s setup.

Wow. What a process, but finding this guy and having it fit as advertised brought it all together. Thank you.

But I kept getting the wrong size. Twice I received the .5" riser when I need and orderd the .8" riser twice. Not a quality issue but .5" doesn't work for me. .8" I could make work but I got .5" twice. Gave up. Customer service was fast but no clue what the problem was and why .5" won't work. So if you need a .5" riser go ahead and order their .8" riser. Quality is nice

I have 2 risers, this one, and the 1" High costs $20. I like this one better for (1) 35% less money (2) This one comes with two cross sided screws (I don't know what it is called), the metal piece sits between rail slots to prevent it from sliding off the mounted position and the other one has flat screws and sits on the rail flush

This riser raises the sight only 0.5", NOT 0.8". Be aware. It served my purpose but perhaps not yours if you need that extra 0.3" of height. Otherwise it's just ok. Install it carefully and torque it carefully or it will cant slightly. I'm disappointed it is no better than Feyachi. It'll do, only just though.
