Customer Ratings & Reviews
I got this mount to mount a tactual light to my wife's Mossberg 500 20ga youth pump. There a lots of options for mounts for 12ga but very few for a 20ga. This mount works perfectly and I would highly recommend it to anyone looking for a 20ga mount.
CDM Gear BMT with 3 slot rail - 20 GA Shotgun
This 20 gauge CDM 3 rail slot mount is spot-on! I am mounting a flashlight on an extended magazine 20 gauge Mossberg 590. I couldn't be happier with the fit, quality or versatility of placement. A sling can be easily attached to the opposite side if desired. It is very low profile and looks awesome. I have a CDM ROC-12 on my Benelli M4 and love that mount. CDM did it again with this 20 gauge mount!
Perfect Front Mount and Clamp
I purchased this for my Remington 870, and it is an excellent choice for a front Mount. I did have my Streamlight TLR-1s mounted on my Magpul forend using a 2" rail. That was good, but I wanted it farther ahead and "off" my forend. I'd heard about the quality of CDM Gear and went ahead and ordered this. I was pleasantly astonished at its quality and functionality. It doesn't show here, but on the other side is a QD mounting hole. I ordered a Magpul QD Sling Swivel when I ordered this. I was shocked again; when I put the sling swivel in, it did not swing around like most QD matchups I had become used to. The sling swivel will stay in place, on an angle or just straight in. The CDM BMT's QD mounting hole has small divots that matched up with the Magpul QD sling swivel; just another bonus for this Mount!! This mount is also one of the lightest one available for a shotgun clamp/mounting system. It's made of sturdy, tough aluminum in a black matte finish. I haven't written many reviews lately, but this was worth letting others know how great this is. I now have a perfect mount for my weapon light and a great place for a QD sling swivel. It also comes with four pieces of thermal tape to protect the finish on your shotgun. Installation is effortless (everything you need is included) I am thrilled with this tight little Mount/Clamp! I'd recommend this to anyone.
