Defining PCC Suppression

At a shockingly light 4.5oz, the F-4 represents a pivotal advancement in 9mm PCC suppressor technology. Much like its predecessor, the AB Suppressor Sabre, the F-4 was designed with dedication in mind, and at heart. Built from 100% grade-5 Titanium and circumference welded for maximum strength, we took our CZ-USA contract-built LEO suppressor design and reconfigured it into the shortest, lightest, and most efficient suppressor in its class.

Much of the F-4’s beauty lies in its simplicity, and ability to seemingly disappear from the end of your weapon during operation due to its near-zero footprint (less than 5 inches, less than 5 ounces).

Perfect for plug and play on any pistol caliber carbine, the F-4 utilizes a flush direct-thread mount which is intended to index on your barrel’s shoulder (or taper for the MPX variant) for an all-muzzle-forward design. The fixed direct-thread mount makes for easy installation/removal, while keeping the overall length and total system weight to an absolute minimum. Wrench flats on the base of the mount make for easy torquing onto your firearm’s muzzle, and ensure the F-4 stays secure during any course of life.
