SIG’s MCX family of firearms feature a short-stroke gas piston system that they claim can be configured in up to 500 different combinations. When it comes to AR platform firearms that are either pistol variants or Short Barreled Rifles (SBRs), size is the name of the game, and shorter is definitely better. SIG knows this to be true, and their MCX Rattler is a home run when it comes to both their pistol and SBR versions of this firearm family.

If you’re looking for a PDW that can be carried discreetly in a backpack or a gym bag, then this is the gun that you’re looking for, hands down.

One of the main benefits of an AR pistol or SBR is the ability to add a suppressor without adding a whole lot of extra length to the overall footprint. That makes the SIG MCX Rattler a prime candidate for a suppressor.

Since this firearm is available in both .223/5.56 and .300 Blackout, we’ll take a look at two suppressor options geared toward each of the caliber selections, with the bonus of being able to run either through the .30 caliber suppressors.

Remember: you can shoot .223/5.56 through a .300 Blackout-capable suppressor, but you cannot shoot .300 Blackout through a .223/5.56 suppressor. Doing the latter will result in damage and/or injury to both equipment and shooter.

There are a ton of suppressors on the market today, and a lot of them can be used on the Sig MCX Rattler, so how do you go about picking the right one?

As we mentioned before, one of the biggest benefits to the Sig MCX Rattler is its size, and you don’t want to muck that up with a gigantic suppressor. Thankfully, because the gun is small, you can run a longer suppressor to get better sound reduction while still retaining a short footprint. You can also get a modular suppressor that lets you choose between long and short configurations. This is the best of both worlds because it lets you choose between overall length and sound suppression levels as the situation dictates.

In addition to considering the suppressor’s length, also consider its diameter. Much in the same way that too much suppressor length negates the purpose of the host gun, so too does a suppressor with an overly large diameter. Not only may it look a little odd, but it could also throw off your sight picture depending on what kind of sights you’re running: scope, red dot, iron sights, off-set backup sights, etc.

Finally, consider how the suppressor is going to impact the overall balance of the firearm. While there are plenty of great titanium suppressors (like the BANISH lineup) that add very minimal weight, that’s not the case with every option on the market. Make sure the suppressor you choose isn’t going to throw off the total balance of your gun.

BANISH 223 – $849

With a sound reduction of 38 decibels, the reduced report provided by the BANISH 223’s expansion tube and seven baffles will not only protect your hearing but also the hearing of anyone shooting around you when you touch off some .223 or 5.56 rounds from your SIG MCX Rattler.

The BANISH 223 is a direct-thread silencer that mounts on conventional 1/2×28 threads. Made of lightweight titanium, this 7” suppressor weighs a mere 9 ounces, so the added length and weight to the SIG MCX Rattler is minimal.

Suppressor maintenance is important, and the Banish 223 is easily disassembled from both ends for cleaning and maintenance. Use a tumbler, ultrasonic cleaner, or a nylon brush; the method of cleaning is up to you. The seven baffles are designed to easily stack and index in any order, making reassembly a breeze.

(Remember: you cannot shoot .300 Blackout through this suppressor.)

YHM’s Turbo T2 was created to supply the modern suppressor community with a full-featured suppressor at an affordable price. YHM accomplishes this by providing a Q.D. Muzzle Brake, a Phantom Q.D. Adapter, and two suppressor wrenches with each unit instead of making them separate purchases. As an added cost-savings bonus, if you already have some YHM products, the Turbo T2 will fit all YHM-5M2 and YHM-3102 mounts.

Coming in at just 6.5″ long with the Q.D. adapter attached, the Turbo T2 is the shortest option on this list, making it perfect for use on a compact gun like the SIG MCX Rattler. On the front of the Turbo T2, you’ll notice the notched rim and tri-port muzzle on the end cap. These features add significant flash suppression, which is very beneficial on an AR pistol or SBR.

Unlike other suppressors that have individual baffles inside of an outer tube, the Turbo T2 utilizes a tubeless design made from heat-treated 17-4 stainless steel along with a heat-treated 718 Inconel blast baffle.

(Remember: you cannot shoot .300 Blackout through this suppressor.)

BANISH 30 – $999

If you’re going to run the .300 Blackout version of the SIG PDX Rattler, then you’ll need a .30 caliber suppressor. (Of course, the Banish 30 would be right at home on the same gun in .223/5.56 as well.) The Banish 30 is a direct-thread suppressor that mounts on conventional 5/8×24 threads and comes out of the box as a 9″ suppressor holding eight baffles.

If, however, you’ll be shooting suppressed in tighter, more confined spaces, then you’ll benefit greatly from this suppressor’s modularity. It can easily break down and assemble into a 7″ configuration with six baffles. Either way, you’ll still get great sound suppression with minimal added length on your Rattler in either configuration.

Weight is just as important as the overall length in this situation. The Banish 30 is made from a strong titanium alloy for unmatched durability at an extremely light weight. In the full configuration, it weighs 13 ounces; in the short configuration, it weighs just 10 ounces. You’ll be hard-pressed to even feel it on the SIG MPX Rattler!

When it comes time for cleaning, the Banish 30 easily comes apart from both ends and is ready to be tossed in a tumbler, ultrasonic cleaner, or cleaned manually. Reassembly is a breeze due to the baffles being keyed and indexed for exact alignment.

(Remember: you can shoot .223/5.56 through this suppressor as well.)
