Frequently Asked Questions

Do I need a threaded barrel to use a suppressor with this adapter? No, that’s the point of this end cap adapter — it lets a fixed-barrel firearm accept a GM-45 or Blackside suppressor without a threaded barrel.

Is this adapter itself an NFA item? No. It’s an ordinary Title I mounting accessory; the suppressor it attaches is the separately-regulated NFA item.
