Monstrum Tactical 1 Offset Picatinny Rail Mount for Flashlights by Monstrum Tactical

Great solid mount for my streamlight flashlight

Very good top quality fit well

solid mount

There are several similar mounts of this style on the market. They look almost identical, so you'd think they are all the same, but they are not. Most of the mounts have a design with a poorly designed clamping mechanism, the part that holds it to the rail. This one has a more substantive clamp that has much better engagement. I had an NcStar mount on two of my rifles before; they look and are sized almost identical to this Monstrum mount. One of the NcStar mounts worked great and I have no complaints about it. The other mount, same NcStar model, wasn't to spec and the rail clamp engagement was really poor and to the point where I could literally pull the mount off the rail very easily with my hand, no matter how tight the clamp screw was. This Monstrum mount has a much better clamp design for the rail that has far better engagement (you can see and compare via the product images). This design could tolerate being fairly far out of spec before failing, relatively speaking; it can't give way unless the product were purely defective. I'm happy with the Monstrum mount I received, so I'm going to order another. I likely just had a bum NcStar unit and I could have just exchanged it and been fine, but the design of this mount is the right design, so it's what I want in service. Note that the NcStar mount may be a few grams lighter. The NcStar has a slightly better designed finger screw in my opinion (it's round and knurled, vs the Monstrum's smooth hex knob), but small difference. I didn't measure it, but the bodies are effectively identical, and the Monstrum has a little more material in both the flashlight clamp, and the rail clamp. Small difference, but if you care about those few grams, it's something to pay attention to.

Seems to be a good product, but to small for the IR light i bought
