A factory Benelli M4 18.5" barrel, ported by Agency Arms. The same porting Agency cuts on its M4 builds: it vents gas up to keep the muzzle flatter between shots and helps the gun cycle lighter loads.
The barrel comes with the gas pistons and front sight installed. It drops onto the gun with no fitting, but we recommend a gunsmith do the install.

This is a firearm. Federal law requires us to ship it to a licensed FFL dealer near you — not directly to your home address. Here's how it works:
- Add to cart and check out. At checkout, use our FFL dealer locator to pick a licensed dealer near you. If your preferred dealer isn't listed, check the box to enter their address manually.
- We verify the FFL and ship. Your dealer can email a copy of their license to support@reactivegunworks.com to speed things up.
- Pick up at your dealer. They'll contact you when it arrives. Bring your ID, fill out the ATF Form 4473, pass the background check/any other requirements relevant to where you live, and the firearm is yours.
