This top-quality silencer is expertly designed to provide exceptional subsonic results with standard high-velocity ammunition, ensuring that you achieve stealth-level quietness without having to purchase subsonic ammo. Specifically designed for the S&W M&P 1522 rifle, this silencer comes in two versions: the standard version (IASW) with a 16.25″ barrel/silencer length and the short-barreled rifle version (IASW-S) requiring two tax stamps.

With a one-piece billet core machined from 17-4ph stainless steel, this silencer is full auto rated, high-performing, and user-serviceable. It comes with a handy tool, and if you ever lose it, you can easily replace it by using any standard 3/8 drive wrench.

Please note that the tube and handguard on the IASW 16.25″ standard length 15-22 integral are permanently pinned and not removable. However, the IASW-S short-barreled rifle, the handguard, and the silencer can be removed. The IASW-S short barrel version has an adapter that allows you to remove the suppressor and attach it to any .22lr rifle with 1/2×28 threads.

the quietest 22 setup we have! super quiet with bulk box ammo. everybody who shoots it can't put it down. my kids absolutely love plinking with it at 150yards on steel, it's possible to get 3 rounds off before the first hits steel.

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.

 by BWatkins

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.
