Maxim Defense DSX-D Suppressor [Review]

If you’re looking for a full-auto rated, short barrel rated, built-like-a-tank suppressor that also offers incredibly low back-pressure and is easy to clean, you’ll find that and a lot more in Maxim Defense’s DSX-D.

Built with some next-level engineering and innovation, the DSX-D is an impressive can. Why? Let’s get into it.

THE FEATURES THAT MATTER MOST

If you’re not well-versed in suppressors, the features of the DSX-D might be kind of lost on you. I know it was for me when I first started talking to Maxim Defense about their flagship can. 

Bottomline, the DSX-D is pretty amazing. Not only does this can have low back-pressure, that’s the gas that comes back into the rifle from the suppressor, but it is also excellent at suppressing the sound of the shot, and is incredibly easy to not only clean but also to repair if needed.

The big deal about the DSX-D is that the suppressor is made of only three parts. The bottom cap that acts as the serialized part of the suppressor, the MonoKore center, and the outer tube.

Because the serialized part is only that bottom cap, that is the only part of the can that the ATF legally cares about. If you ever get a baffle strike or somehow damage your MonoKore or tube, you can have it repaired by Maxim with little trouble and no ATF paperwork.

And because it breaks down into these three parts, cleaning the DSX-D is super easy. The MonoKore features carbon cutters that will scrape the inside of the tube as you unthread the tube from the base cap. The extra-long threading on the cap gives you leverage and more cutting passes to help the MonoKore clear out all of that carbon. 

Once you have the tube off and the MonoKore out, the two parts are easy to clean.

To top it all off, the DSX-D can be directly threaded on to a barrel and pinned and welded in place. Throw this can on a 10.3” barrel, and after pin and welding, you’ll have a 16” rifle that only needs 1 stamp for the can.

SHOOTING EXPERIENCE

The DSX-D feels and sounds great. I got to test it on a 10.3” barrel, full-auto Maxim Defense rifle. In semi-auto the can sounded low-toned and comfortable at my ear with almost zero gas being blown into my face.

On full auto, the sound remained pleasant at my ear, and the gas felt more like a light puff. As far as full auto 5.56 cans go, this was one of the best experiences I’ve had. 

A lot of suppressors claim to be full-auto rated, but seeing Maxim’s rifles chugging out full auto fire all weekend at CANCON Georgia 2023 was impressive. The Maxim Defense rifles kept up with some heavy demands, and I never once saw them malfunction or come off the line.

Shooting with the DSX-D was one of the highlights of the event.

Full-auto mag dumps were easy to control, didn’t overwhelm my hearing, and didn’t compromise my vision from the gas. Normally, a full mag dump with a suppressor leaves you breathing in gas like Deadpool huffing his Dester Eagles. With the DSX-D, I could smell the gas, but it wasn’t enough back-pressure to suffocate me or even irritate me. It was shocking how well the DSX-D worked in practice. 

LOOSE ROUNDS

I was genuinely suppressed and impressed with the DSX-D and with the Maxim Defense rifle I shot it with. After shooting a shmorgishborg of suppressors, the DSX-D was the one that made the top of my personal list of cans I plan on acquiring soon. 

With the ease of cleaning, ease of repair, low back-pressure, and wonderful sound suppression, the DSX-D is an impressive can and won’t break the bank.
