MTRS-12 Pro Series Shotgun Light Mount for Mossberg 590 Shockwave
Mounting a light on a Mossberg 590 Shockwave isn’t as simple as bolting on a generic clamp. Space is tight, balance matters, and many mounts either don’t fit correctly or shift once you start using the shotgun. The CDM Gear MTRS-12 Pro Series Light Mount was designed specifically to solve those problems.
This is a compact, lightweight shotgun light mount that clamps directly to the magazine tube and provides a clean, secure 3-slot Picatinny rail for your weapon light. It’s purpose-built for the Mossberg 590 Shockwave, not adapted from a full-size shotgun mount.
Why the MTRS-12 Light Mount Works Better
Built for the Shockwave platform
The MTRS-12 is sized to fit the limited mounting space of the Mossberg 590 Shockwave. Many universal shotgun light mounts simply don’t fit this platform correctly or interfere with handling.
Secure mag tube mounting
This mount clamps firmly to the magazine tube and is designed to stay in place even when the barrel is removed. Once installed, it doesn’t walk or rotate under normal use.
Left or right side configuration
You can mount the rail on either side to match your dominant hand and preferred activation method. This makes it easier to set up pressure switches or tail-cap activation without awkward hand placement.
Lightweight and low profile
At approximately 1.7 ounces, the MTRS-12 adds minimal weight to the front of the shotgun. The low-profile design keeps the setup compact and balanced.
QD sling compatibility
Each mounting position allows for a quick-detach sling swivel option on the side or bottom, giving you flexibility without adding extra hardware clutter.
Materials and Finish
The MTRS-12 Pro Series is machined from aircraft-grade aluminum and finished with a durable black anodizing. The result is a mount that’s strong, corrosion resistant, and built to handle hard use without unnecessary bulk.

Why Choose a Dedicated Shotgun Light Mount
A shotgun light mount should not be an afterthought. Generic mounts often compromise ergonomics, loosen over time, or simply don’t fit compact platforms like the Shockwave. The MTRS-12 is designed around the actual dimensions and use case of the Mossberg 590 Shockwave, which is why it delivers a cleaner fit and more reliable performance.

What a pleasant surprise this one was. I was about to buy the GGG brand one but read about some flex/durability issues. At first, I thought it was a UTG/Chinese junk part. Nope. Texas company who stands by their gear, and it installed quick and easy and does a great job of holding a light and acting as a sling mount both. And its low profile enough to not look stupid and bulky. The perfect accessory to finish off my 590 SBS. Thanks, guys. Great product.

Looks great works great what's not to like. It is a little on the pricy side, but there the only option for the shockwave and its aluminum, which is expensive to CNC mill, took some thinking to make.

This Mossberg shockwave light mount is attached to the gun by clamping itself around the magazine with a screw. It clamps tight and doesn’t move. It fits more secure than other mounts I’ve seen that are held on by the magazine end cap.

I would give this Shockwave sling & light mount six stars if I could. Very simple to mount and stays put after running high brass loads. It looks great and is a must-have to install a light on a Mossberg Shockwave. I have the GG&G mount on another Mossbergs, but this design is much stronger. Do not wait if you want to add a light and sling mount to your Shockwave.

I would give this CDM Gear Mount 6 stars if I could. Mounts effortless and stay put after running high brass loads, sees good and is a must-have to mount a flashlight on a Mossberg Shockwave. I have the GG&G mount on my other Mossbergs, but this design is better. Do not hesitate if you want to add a light and sling mount to your Shockwave.

This is the second mount I've purchased from CDM, and as before, is a brutally solid mount for your Mossberg Shockwave.....in fact, I'm stepping up and rating it THE #1 and only weapon-specific multifunction mount for your 12ga Shockwave. This is built like a brick outhouse!!! Can be mounted for either L or R hand use. This and customer service is speedy and efficient. What more can you expect!!! I highly recommend this mount for any Shockwave owners out there looking for a no BS light or laser mount. Not some airsoft toy garbage, but the real thing. Buy with EXTREME confidence.

This mount is solid, as well as compact. It moves my light and laser in closer to the fore end and back about an inch farther than the mount I was using while this item was on back order. It gives my shotgun a cleaner, more streamlined appearance, it stands up to the recoil, and is easy to install or remove. It was well worth the wait.
