What ammunition should I use with my IASW?

  • The design of the IASW allows you to use almost any factory ammunition that you want that is .22lr on down in size, velocity, energy and pressure, and is the correct ammunition for the firearm. Please contact us if you have any questions.
  • You can use standard velocity and still get subsonic results.
  • We have had great results with standard velocity CCI ammunition.
  • The firearm manufacturer has told us that they do not recommend the use of Winchester ammunition.

Does the IASW suppressor void my firearm warranty?

  • The IASW is a barrel modification and should not void your firearm’s factory warranty. We recommend reaching out to the firearm manufacturer for their specific warranty information.

Can I remove or swap-out my handguard?

  • No. Once the barrel is integrally suppressed you can not remove the handguard.

Can I remove or swap-out my IASW integrally suppressed upper and put it on an AR15 chambered in .22lr?

  • No. The S&W M&P 1522 upper is not interchangeable with other AR platforms (it will not fit).

Why won’t my firearm cycle?

  • New firearms may need a break in period.
  • Clean the firearm.
  • Use a few drops of gun oil.
  • Try a different magazine.
  • Try different types of ammunition.
  • Contact the firearm manufacturer.
