Here’s what Maxim Defense have to say about the .338 MSX Suppressor:

Maxim Defense, premier manufacturer of precision firearms, suppressors, and accessories, is proud to announce the new MSX Suppressor in .338 caliber. The MSX Suppressor by Maxim Defense is specifically designed to minimize the increase in cyclic rate and gas blowback of a suppressed weapon system.

“We couldn’t be more excited about this new suppressor design,” said David Farrell, Vice President of Commercial Sales, Maxim Defense. “The goal of the PRS Suppressor was to increase reliability and longevity for the host firearm compared to other, more traditional, suppressor designs.”

The new MSX Suppressor features a MonoKore™ 3-piece design with a suppressor core that has integrated carbon cutters for tube cleaning. Specifically designed for .338 caliber, it has a limited rate of fire of 20 rounds, at 1 round per second. This suppressor achieves unparalleled strength in design, by achieving a previously unmatched strength to weight ratio. It’s made from military grade materials including 7075-T6 aluminum with type-III hard coat anodizing and a grade-5 Titanium thread insert.

The new Maxim Defense MSX Suppressor incorporates state-of-the-art features including the significant reduction of sound signature, well below hearing-safe levels, while decreasing the flash signature and reducing recoil, for increased accuracy. Results vary based on weapon configuration, ammunition, barrel length, and atmospheric conditions. This unique suppressor is designed to be the lightest suppressor possible for PRS competition shooting and all hunting situations.

    Let me get this straight : this is an aluminium, flow-through .338 suppressor rated for rapidly-paced short strings of fire ? With those features, the only host on which it makes sense is a semi-auto precision platform, but nobody uses that, because nobody has a use for quick follow-up shots with a cartridge designed to shoot targets past a kilometer. And if they do, what they actually want is probably a machine gun, not a .338 DMR.

      @IOJ I think this is designed for the Q Boom Box cloners. 8.6 Blackout is starting to get more attention in the gun media.

    One grand for aluminum centerfire suppressor?

    • Abel_Archer83 Abel_Archer83 on May 09, 2024

      @Mongo I don't know much about silencers but aluminum and something high pressure like 338 Norma or 338 Lapua sound like they would wreck it in quick fashion. Now subsonic 8.6 Blackout I could see working ok.
