300 Blackout Suppressors FAQ
Do I need a dedicated 300 BLK can?
No. Any can rated for 300 Blackout works, and that includes many 30 cal cans. Check the rating on the product page.
Why will my rifle not cycle subsonic ammo?
Subsonic loads make less gas. Many rifles run better with a can on, and some need a different buffer or gas setting.
Is a 300 BLK can rated for 308?
Some are and some are not. A can built for 300 Blackout pressures may not be rated for full power 308. See 308 & 30 Cal Suppressors.
Suppressor laws vary by state, and some states ban them outright. Check the rules where you live before you order. We cannot give legal advice. Questions go to gungearwarehousellc@gmail.com.
