Simple, Easy, and Quiet!

This integral suppressor is designed for the S&W M&P 1522 rifle and is available in two versions – a standard 16.25″ overall barrel/silencer length, or as an SBR. The SBR version is a two tax stamp firearm. This integral features a one-piece billet core machined from 17-4ph stainless steel and is user-serviceable. Each integral comes with a tool, although you can also use any standard 3/8 drive wrench. The unique design of this suppressor provides subsonic results with standard high velocity ammunition, so there’s no need to buy subsonic ammo to be stealth quiet. Please be aware that the tube and handguard on the 16.25″ standard length 15-22 integral is permanently pinned and not removable. Click the tabs below for more information and customer reviews.




SBR Length: Barrel 4.5″, Suppressor Length 8″ *SBR is a two stamp firearm and the complete silencer, including the tube is removable on the SBR version. 

*Please be aware that the tube and handguard on the 16.25″ standard length 15-22 integral is permanently pinned and not removable.

Picked it up today from Precision Sports in Oshkosh, WI. Quality is perfect. Sound is amazing. Using bulk ammo makes it better than my old 15-22 with a Sparrow. Still love the sparrow but bulk ammo as quiet or quieter than my sparrow with suppressor ammo is fantastic. Innovative Arms received my new 15-22 and had the integral done before I thought possible. Everyone needs this integrally suppressed 15-22. This gun is awesome. Sell a kidney if you need but buy at least one of these.

Just brought it home today after 9 months of wait on the ATF for my tax stamp and all I can say is...WOW! It's about as loud as a snail fart! It was worth the wait.

I watched the youtube video and had to have one. I have the IASW .22lr integral suppressor by way of the M&P 15/22. Just as in the video, running regular off the shelf bulk ammo this thing is super quiet and tons of fun. It was a breeze to take down for cleaning as well. Love it!

I have wanted one of these since I first learned about them a few years ago and thanks to Silencershop, I finally have one and am delighted with it, my third suppressor. Since its arrival I have shot nothing else. With my other suppressors on bolt guns I use subsonic ammo and love the ultimate quiet, but I have to say its great to burn low cost HV bulk .22 like Winchester Wildcat and CCI Blazer subsonically. BTW, subsonic and premium match SV will not consistently cycle this ported barrel rifle.

Literally the only sound you hear is the action cycling and the sound of the bullet impacting down range.

Hands down my favorite gun to shoot. It's so quiet the whole family shoots this thing, from my 8 yo daughter to my granddad.

This suppressor is very quiet and flat out fun to shoot! Very happy with my purchase.

Stupid Quiet

I get the most fun out of this integral over all my other firearms.  I appreciate that I can use high velocity ammo and save some money.  People can't believe how stupid quiet it is.

As both a dealer and end user for/of Innovative Arms, I’m incredibly impressed from both sides. The IASW is BY FAR, the most impressive integral and easiest to sell suppressor I’ve sold. I’ve only had one customer that demo’d it that didn’t end up buying one. It’s like going to look at puppies, they just sell themselves. I’ve enjoyed working with both Philip and Jenny and they have always taken care of me as a dealer. I even caught Philip in a week moment and worked a one off HK MP5SD .22 out of him somehow. That one is AWESOME! Keep up the good products and keep up the GREAT customer/dealer service. Thanks Innovative Arms.    www.redriverrange.com

This is one of the best on the market, I have one of the competitors and this one blows it away. I love the ported barrel. It allows me to shoot any ammo out of it. WAY TO GO! PEW PEW PEW www.texasgunsandsurvival.com
