Maxim Defense showed off some enhancements to their integrally suppressed Ruger MkIV-SD pistol.
Based on the Ruger MkIV .22 LR pistol, they add their MSX suppressor. The pistol is offered by Maxim either with or without a Delta Point Pro optic but they’ve recently created two new accessories you can outfit your MkIV SD with.
There’s a new optics mount with integrated cowitness back up irons. There’s also an add-on so you can mount a light to the pistol.
New from Dead Air Silencers is the Sierra 5, their first dedicated 5.56 (5.56/.223, 224 Valkyrie) can.
There are two versions, compatible with either KeyMo (top) or Xeno (bottom) mounting systems as well as a direct thread model.
The construction is welded Stellite baffles wrapped in a stainless, knurled outer tube. Stellite is a Cobalt alloy with a 2300 F melt point.
It also has a flash hider front cap compatible with Sandman E-Brake and all R-Series front caps which can be swapped out in the event of a front cap strike.
Here you can see the difference in size between the Sierra 5 (bottom) and Dead Air’s military issue suppressor.

Tampa, FL (May 24, 2022) – B&T USA is excited to announce it has begun shipping its all-new SPC9 PDW SD short-barreled rifle (SBR) configuration featuring an integrally suppressed, ported barrel system compatible with an included RBS (Reduced Backpressure System) suppressor.
“The SPC9 PDW SD is modern and unique in many ways, while at the same time providing familiarity” said Jon Scott Vice President of Sales, B&T USA. “This integrally suppressed model features a non-standard suppressor design that performs as advertised, while at the same time boasting a slim, ergonomic handguard with useable M-LOK compatible slots for mounting enablers.”
The PDW SD is the fifth model in the SPC9 line-up, joining a 4.5-inch barreled PDW, 9-inch Standard, integrally suppressed Standard SD and a 16-inch Carbine. Each are lightweight and reliable, well balanced and accurate, safe and modular — the SPC9 checks all the boxes and is one of the lightest recoiling 9mm carbines available, thanks to B&T’s innovative and effective hydraulic buffer system.
Some of the features found on the SPC9 are time proven while others are state-of-the-art and modern. One of the unique features of SPC9-series is that it is equipped with two different charging handle systems. One of these is the handle found on AR platforms, while the other is a non-reciprocating, foldable charging handle located above the barrel. This gives the user the choice to use whatever manual of arms that is preferred; both systems are ambidextrous.
Like many B&T SMG’s, the SPC9 accepts all APC9 PRO lower receiver groups, meaning it can be equipped to accommodate Glock magazines, SIG P320 magazines or proprietary B&T magazines, by simply switching the non-serialized lower receiver group.
Watertown WI, May 20th, 2022– The Griffin Taper Mount system has been satisfying customers for over a decade with it’s simplistic, robust, and affordable mounting system. A QD system however, offering an active retention system is often times demanded by government customers. A quality QD system should be accurate, robust, reliable, require minimal training, and be free of wear prone metal on metal teeth or ratchets, thereby guaranteeing a longer trouble free service life with minimal maintenance needed. Griffin’s DUAL-LOK™ QD mounting system was designed around these objectives.
What makes this mounting system unique? It is a combination of desirable mechanical features and performance characteristics in a lightweight, yet compact system. DUAL-LOK™ has great potential for widespread product application. A precision taper interface (one locking feature) between the mount and the device ensures accuracy. An ACME thread, provides speed and ease of attachment. A robust 17-7 Wave spring (718 Inconel on DUAL-LOK™ suppressors) provides a reliable and positive heat resistant spring action to the redundant locking collar (second locking feature). The locking collar is semi permanently installed to the mount via factory pressed splined taper pins. Since the mount has no wear prone metal on metal sliding actions like many other mounts, there is no need for the operator to disassemble the system. This locking ring includes three anti-rotation teeth which ensure the suppressor will not come off inadvertently. The muzzle device integrates 60 machined anti-rotation splines which is doubled by the mount’s two locking positions, hence the double entendre DUAL-LOK™. How is this achieved? The mounts’ two locking positions are machined out of phase of one another by 3 degrees which provides the system with 120 different locations to lock and ensures that when the suppressor is firmly screwed onto the taper a locking spline will be at an ideal location to ensure a rigid and locked suppressor. When the suppressor is firmly attached, only one of the two lock positions will work allowing the spring to push the locking collar rearward over the splines. Every time the operator attaches the suppressor they will articulate the collar to this same locking position.
Substantial efforts are taken in the manufacturing and inspection of the DUAL-LOK™ products to ensure Griffin customers are outfitted with some of the best QD mounting systems in the world.
“I have been studying and designing silencers most of my life, and I am very proud our team for it’s diligence to provide a world class QD mounting system to the market second to none. I spent years, many sleepless nights, dreaming up a system that would check all the boxes and be truly great. We were able to do that. It was a very fun project for me and I am excited to be integrating the DUAL-LOK™ system in several interesting suppressors over the next few years. I have confidence that demanding customers will be well satisfied by this invention.”

It’s said in the industry that it’s easy to make a 22 suppressor, but to make a good one is another story. Maxim Defense has taken the 22 suppressor to a whole ‘nuther level with its new DRF-22.
They’ve been seen and discussed before, but we will provide you with a little more detail.
DRF-22 (Direct Thread Rimfire) 22 Suppressor
Why the DRF-22? Because the DRF-22 suppressor is specifically designed to minimize the increase in cyclic rate and gas blowback of a suppressed rimfire firearm.
Primary design features include the significant reduction of sound signature, decreasing flash signature, reduction of recoil, and increasing the accuracy of the suppressed firearm.
And let’s be honest. Who wouldn’t want a suppressed .22? With the right ammo, the most you will typically hear is the action of the bolt. What’s not to like about that?
Things to Know
There are four unique characteristics of the Maxim Defense DRF-22 rimfire suppressor that a potential user/shooter should know.
1 It is user-serviceable. This means that you can disassemble and clean the suppressor without having any specialized tools or having to send it into Maxim Defense. If the core itself becomes compromised from a bullet strike, all you need to do is remove the core from the tube and send in that part; there is no need to send in the serialized part and deal with the red tape of replacing that.
2 The suppressor has been designed to mitigate First Round Pop significantly; see below for more information.
3 The suppressor tube has an integrated carbon scraper. As you unscrew and pull the tube from the core, it scrapes any excess carbon from the internal core of the suppressor.
With some other suppressors on the market, after running a lot of rounds through them, the threads tend to lock up, and you cannot remove the suppressor from the gun. Maxim Defense has put the time into their thread design to ensure the suppressor stays secured to the weapon, but it will unthread with minimal effort when it comes time to remove it.
What is First Round Pop?
First-round pop is defined by the volume of the first round fired minus the average of the volume of the remaining rounds fired.
In a typical case, the first round fired is much louder than the other rounds that you would fire. There are several contributing factors to first-round pop.
First and foremost: before the first round is fired, the suppressor is full of an oxygen-rich atmosphere. This oxygen encourages a secondary detonation inside the suppressor as unburnt and burning gun powder enters the device.
After the first round is fired, the suppressor is immediately full of carbon dioxide instead of oxygen; additional detonations do not occur. There are other causes of first-round pop, but this is the most common.
Two others are:
• Ammunition. Pressure. Pressure is generated in different measures by different loads. Therefore, separate versions even of the same cartridge (and/or manufacturers) may react differently.
• Barrel length. Barrel length also contributes to first-round pop. As a result, short-barreled weapon systems tend to have first-round pop than their longer barrel counterparts.
Maxim Mitigation
Maxim Defense 22 suppressors, for the most part, are designed to negate or, at a minimum, significantly reduce first-round pop. The internal geometry of the suppressor baffles are what tend to increase or decrease first-round pop.
When Maxim Defense designed its monocore, they went to great lengths to find the right combination of entrance chamber volume and baffle geometry (fluid resistance). Its DSX and PRS line of suppressors have an integrated M baffle in the entrance chamber that significantly reduces or negates all first-round pop entirely. Its line of 22 suppressors does not have an integrated M baffle, as it turns out that they do not need it. The baffle geometry that they had designed worked perfectly on its own. For the .22, it all came down to a mathematically and geometrically optimized monocore.

Maxim Defense is now manufacturing suppressors. Beginning with one for a belt-fed, then the DSX-D (Duty Suppressor System – Direct Thread) suppressor, plus the DRF-22 (Direct Thread Rimfire) suppressor, with more to come.
And none other than Phil Dater is helping them do it.
Maxim Suppressor Development
After S&W acquired Gemtech Suppressors and moved the company cross country, Maxim Defense was privileged to hire many of the talented people who remained behind. One of those people was Phil Dater. You might remember his name from the founding of Gemtech and the excellent work done by Antares Technologies in the modern small arms and suppressor industry.
Michael Windfield, founder and owner of Maxim Defense, launched the development of Maxim’s suppressors with the directive, “We do the hard stuff first.” Hard stuff in this context refers to successfully suppressing an FN MAG belt-fed machine gun, which they did.
Having checked that box, they began developing a full line of suppressors. Those devices are now dropping sound levels well below the OSHA hearing safe threshold of 140dB. For example, the average measurements taken per MILSTD-1474D while testing the DSX-D suppressor were 134dB on a 10.3″ AR-15 chambered in 5.56 and 114dB with the DRF-22 rimfire suppressor. These sound levels were measured at the shooter’s ear.
Maxim Defense DSX-D Suppressor
The DSX-D (Duty Suppressor System – Direct Thread) suppressor is specifically designed to minimize a suppressed weapon system’s violent cyclic rate and gas blowback.
The suppressor consists of a three-piece MonoKore design that adds 7.25″ to the muzzle of your rifle. The DSX-D is rated for full auto in all available calibers; 5.56mm, 7.62mm, and 6.5 Creedmoor.
There is, however, an 8.5″ barrel restriction. Additionally, the suppressor can be pinned to a 10.3″ barrel to give you a 16″ overall barrel length essentially.
