First Look: Maxim Defense Unveils New Suppressors, Frangible Ammo, and Integrally Suppressed Rifles – SHOT Show 2022

Maxim Defense brought a host of new products to SHOT Show 2022, and we got the chance to take them for a spin at this year’s Range Day.

Long known for their high-quality AR-style rifles and accessories, the company is rolling out four new suppressors, two new integrally suppressed firearms, and a new line of frangible ammunition. Pricing is yet to be announced, but company reps said we’ll have that information before the new products ship in the second quarter of this year.

Leading the new suppressor lineup is the MSX-240, a beefy, 10.7” .30-cal suppressor designed to be used on the FN M240 machine gun. This suppressor is belt-fed rated, constructed from 17-4 H900 stainless steel, and can take the nastiest abuse you can throw at it.

Next come two additional 7.62mm, 6.5mm, and 5.56mm cans that all measure 7.9” in length and 1.75” in width.

  • The PRS-DC is designed with precision rifle shooters in mind. It’s a direct-thread can constructed from grade-5 titanium and 7075-T6 aluminum and can drop the shot report of a 6.5 Creedmoor round down to 131.9 decibels. At only 10.8 ounces, it’s one of the lightest, toughest cans on the market today. The PRS will be available in 7.62mm and 6.5mm.
  • The SDC will be available in 7.62mm, 6.5mm, and 5.56mm, and is Maxim’s entry in a new SOCOM suppressor solicitation. It’s constructed from grade-5 titanium and 17-4 stainless steel and weighs 21 ounces. It’s full-auto rated, and a company rep told us they turned the can white hot in testing, and it still performed. The SDC reduced can reduce the shot report of a 5.56 round down to 134 decibels from a 10.3” AR-15. It will be available in direct-thread and QD mount models.

Rounding out the new suppressor lineup is the DRF, a direct-thread rimfire suppressor that is rated for .22 Magnum, measures 5.9” in length, and only weighs 3.5 ounces. The simple three-piece design is user-serviceable with common tools, and Maxim claims that it eliminates first-round pop.

Maxim is also introducing an integrally suppressed Ruger Mark IV (called the MKIV-SD) using their new rimfire can. The suppressor increases the overall length of the handgun to only 12.6”, making the MKIV-SD a great plinker or competition pistol.

Next, Maxim showed us the SDX-508/510, their new line of integrally suppressed rifles available in 5.56 NATO and 7.62x39mm. Maxim will offer the option to have the suppressor pinned and welded to a 10.3” barrel, which will increase the length of the barrel to 16”. This means that rather than purchasing two tax stamps—one for the suppressor and another for the short-barreled rifle—customers will only have to purchase a single tax stamp for the suppressor.

Finally, Maxim Defense also unveiled a new line of 5.56 NATO frangible ammunition. This ammunition can be shot safely at steel targets from only one meter away, and unlike other frangible ammunition, is safe to use in suppressors.

This frangible ammo can be shot at steel from 1m away and is safe to be shot through suppressors.

As of this writing, these products do not yet appear on Maxim’s website, but you can still learn more about the company by clicking HERE.

Products and pricing should be available in quarter two of this year.
