Optimal Optic Positioning
Raise your optic to the next level with the Monstrum Tactical Lockdown Series Riser Mount! Built for use with Picatinny or Weaver base optics, our mounts will give you just the right amount of rise for optimal red dot/scope positioning.
Redesigned Heat-Treated Locking Nut
The redesigned, heat-treated locking nut fastens securely via hand, screwdriver, or wrench providing extreme lock down for the heaviest of recoils.
Hollow-Body Design
The new Lockdown Series Riser Mounts include a hollow body design and an improved attachment mechanism. The single piece machined aluminum profile is designed to shave off precious ounces of weight, making it our lightest and sturdiest riser mount yet.
Get More Control Over Optic Placement
Place your scope exactly where you want it! This riser mount allows you to place your scope beyond the limits of your rail. The hollow body, medium profile design allows for optimal head placement.

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.

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.

This riser seems to be well made and accurate in its dimensions. It fits perfectly on a Bushmaster AR and raises the scope almost perfectly to eye level. The thumb nuts allow it to be securely attached, and I foresee no problems with anything coming loose. It's a good product for a good price.

Very solid with rail are to spec. Only issue would be the side bolts needed to tighten. They work; however very bulky

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.

Decent item but it was not what I wanted - this riser will NOT fit an Eotech XPS or the Magnifier as the thumb screws are the same level as the riser, thus not allowing anything that is wider that the rail to be mounted except for the 1 or 2 notches in front or behind the bolts in between.

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

Works well for both increased height and or extension of a small pic section
