The Agency Arms 118 Compensator is threaded with the standard 1/2x28 thread pitch (Overall barrel protrusion should be 0.695" +/- 0.005" for optimal fitment). The Dual Port version features a 2 chamber design (2 vertical ports and 2 side venting ports, while the Single Port version offers only a single top vent. Compatible with the M&P9 (3.6", 4", 4.25" and 5") platform. (NOT COMPATIBLE WITH CONVERSION BARRELS)
*Compensator may require tuning of Recoil System. Designed to work with most factory loaded ammunition but will yield the best results with a heavier charged ammunition*
The package includes:
- 118 M&P Compensator
- 2 Set Screws with an Allen Wrench
- Vial of Thread Locker
*These compensators are designed to fit best with Agency Arms barrels, some aftermarket barrels have different standoff distances which can cause a gap between the compensator and slide*
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.
