SW MP 15- 22

Smith & Wesson’s M&P 15 22 is a quality firearm that will quickly become anyone’s rimfire favorite. The M&P 15 22 is Smith & Wesson’s .22 variant of the tactical M&P 15 semi-automatic rifle. This firearm is designed for recreational shooting (plinking) as well as small-game hunting. 

It was modeled after the traditional AR-15 but – thanks to the lower forces of the smaller 22 LR cartridge – is made with lighter materials (polymer upper and lower receiver) rather than the conventional aluminum alloy found on ARs.

If you want to quiet down your M&P 15-22 to save your ears (or prevent annoying your neighbors) a .22 caliber suppressor is a must-have. 

Suppressors are the most effective way to dampen the sound of your firearm and – while not a functional consideration – look pretty boss. They’ll add length and weight to any gun, so it’s important to know what to look for to ensure you get the benefits of a quieter firearm without throwing off its balance. Luckily, we’re here to help.

The Best M&P 15-22 Suppressors Reviewed

1. Best Overall: Silencerco Sparrow 22

Suppressors aren’t just designed to quiet down your rifle – they can make shooting much more entertaining and keep you from irritating your neighbors. The SilencerCo Sparrow 22 does all that and more. 

Despite a decade in the market, this solid, multi-caliber suppressor still performs with the best of them. It supports 7 different calibers, sports a full-auto rating, and when paired with sub-sonic ammo will quiet your rifle down to a whisper. 

You’ll hear the action of your firearm and downrange impact of your rounds well above the report of the gun. Lots of fun to be had. 

The Sparrow’s monolithic core gives it a good combination of weight and durability while making it easy for anyone to service. If you want a single suppressor for all your rimfire guns, the Sparrow 22 might be the suppressor for you. 

Beyond .22 LR, the Sparrow can reduce the .17HMR down to 124db, and 5.7×28 to 127, so while the .22 LR will give you the most sound suppression, you’ll get solid performance across multiple calibers.

What We Liked

  • Multi-caliber
  • DB reduction for a .22 LR down to 11dB
  • Monolithic core is very easy to service
  • Full-auto rated

What We Didn't Like

  • Not cheap
  • Weighs 6.5 ounces
  • Not the newest tech

2. Best Sound Suppression: DAA Mask 22

The Dead Air Mask 22 is a phenomenally effective, well-engineered suppressor that fits any standard ½-28 direct threaded barrel. 

In terms of sound suppression, the Dead Air can reduce a 22 LR report down to under 110db, which makes it one of the most effective suppressors available anywhere. This is also going to make shooting safer and more fun for almost anyone, especially children who might recoil with standard rifle report.

That additional performance comes with a price, as the Dead Air is more expensive than many other options. But if performance and build-quality top your list of must-have features look no further than the Dead Air Mask 22.

What We Liked

  • Well engineered 
  • Affordable
  • Titanium exterior
  • Shockingly effective at suppressing reports
  • Full-auto rated
  • Lifetime warranty
  • Fully user-serviceable

What We Didn't Like

  • End cap requires tool for removal

3. Also Great: SilencerCo Specter 2

The SilencerCo Spectre 22 is an impressive silencer for the money and, while not the lowest-price option available, it’s considerably cheaper than the typical $600-$700 suppressor asking price.

The Spectre’s 1” exterior diameter makes it a near-perfect fit for pistols like the Ruger Mark IV, giving it some serious Ian Fleming vibes. Offering a remarkable combination of price and quality, the Spectre 22 is a simple, well-built suppressor that will have you stealthing through the woods in near silence for years to come.

What We Liked

  • Sound reduction of 41 dB
  • Full-auto rated
  • User-serviceable

What We Didn't Like

  • Heavy at 6.5 ounces

4. Budget Option: Creative Arms

The Creative Arms Direct Thread 22 LR Suppressor is both inexpensive and high-quality – with impressive shot suppression for a product that weighs in at a remarkably light 3 oz. Paired with subsonic ammo your M&P 15-22 will be virtually silent – and enable you to get multiple shots off on predators or varmints without spooking your prey.

The thread-mounted suppressor does require a threaded barrel, so it’s not a product that offers quick attach/detach, but it is possible to switch between guns provided you’re working with ½-28 threads. If you’re looking specifically for a dedicated M&P 15 suppressor, then the Creative Arms Direct Thread should absolutely be on your list.

What We Liked

  • High degree of sound suppression
  • User-serviceable
  • Incredibly light at 3 oz
  • Easy to mount with ½-28 threads
  • Inexpensive

What We Didn't Like

  • No quick detach
  • Not as proven as products from SilencerCo and others

5. Honorable Mention: Innovative Arms

Innovative Arms is known for making high-quality suppressors and the Slingshot is no different. This one makes our list thanks to its mix of sleek design and the availability of a Micro option which is around 3.5 inches in length. That diminutive can is a remarkable feat considering how effective it is at suppressing the sound of your shots.

The Slingshot also comes in five different finishing options, so you can match your M&P15 or go for something that creates contrast – it’s all up to you. 

If paying a little more isn’t an issue and you want the upgraded materials, highly customizable design, and the shortest possible suppressor the Slingshot is worth a look.

What We Liked

  • Only has three components
  • Two models available: all stainless steel and a stainless steel/titanium blend
  • Shorter than many suppressors at 4.5 inches
  • Different finishes available
  • Sound reduction of 38-41 dB
  • Is full-auto rated and can be used with multiple calibers

What We Didn't Like

  •  Stainless steel option is on the heavier side at 6.3 ounces
  • Is a monocore, which can result in significant first-round pop

What to look for in a Quality 15-22 Suppressor


The most important consideration for a suppressor is how well it, you know, suppresses the report of your gun. You can normally find this information on the specs section of the manufacturer’s website, but many live-fire tests are available in reputable online publishers or YouTube which provide detailed shot-to-shot decibel measurement comparisons. 

In general, better suppressors reduce sound by more decibels.


Suppressors aren’t cheap, and any reasonable shopper will need to consider price – possibly even above performance given these little cans can cost more than the firearm they attach to. 

In general we recommend to shop with a budget in mind and stick to it – which means you may not be able to pick-up the very best silencer on the market. Of course, anyone in the market for a suppressor will absolutely want the best value for their money. 

If, however, performance tops price in your world the extra cost of a highly performant suppressor may be worth it.

Weight and Size

The weight of a suppressor matters because the can screws onto the very end of your firearm’s barrel. Coupled with the fact most .22 LR firearms have less mass than larger-caliber guns, and you can seriously throw off the balance of a gun by slapping a suppressor on it. This is especially true for a .22 LR pistol.

If you are purchasing a suppressor for a rifle you’ll have more wiggle room on the scales, and can likely run something a little heavier without torching your balance. Still, everybody has their preference and weight may simply be the most important attribute for you if balance is key to your comfort behind the trigger.

The diameter and length of the suppressor are also critical factors to consider. Length because the further the weight of a suppressor hangs out front the less it can feel. Some people also just don’t want a bulky attachment. 

Larger diameter suppressors can impact a pistol’s sight picture, which some people don’t mind, but others still want to have their sights align with the target (vs the back end of their suppressor.) In these cases you’ll want to consider suppressor-height sights to get your dots above the can.


A suppressor’s material impacts both durability & weight. Stainless steel is a good base material for most, while others may opt for an even more lightweight material like aluminum or titanium. As with any weight-conscious accessory – lighter materials generally translate into more cost.

Other Factors

Some other factors that you might want to consider when purchasing a suppressor include things like color, user-serviceability, and whether or not it has a full-auto rating. Experienced gun enthusiasts will likely have a preference for all of these factors depending on the gun they plan to mount the suppressor to.


Selecting the top suppressors for a fantastic gun like the M&P 15-22 is tough, but we think the SilencerCo Sparrow 22 is the best overall suppressor for the tactical rimfire from Smith & Wesson. The Sparrow is relatively lightweight, offers impressive sound reduction, looks great, is user-serviceable, and is a proven performer.

Some suppressors may be lighter or use higher tech materials, but the Sparrow offers the best combination desirable qualities without running up the tab. Happy hunting!
