AB SUPPRESSOR
The AB Suppressor 9mm PCC F4 with 1/2-28 direct-thread mount is a lightweight, titanium-built suppressor engineered specifically for pistol caliber carbines. Weighing just 4.9 ounces, this compact 9mm PCC suppressor delivers the minimal footprint and weight savings that serious PCC shooters demand, without sacrificing the durability or sound reduction needed for high-round-count range sessions and competition.
Built entirely from Grade 5 titanium and circumference-welded for maximum structural integrity, the F4 uses a fixed direct-thread mount that threads onto your barrel's shoulder (1/2-28 pitch). The flush, all-muzzle-forward design keeps the overall system length minimal while the wrench flats at the base allow for tool-assisted installation and removal, ensuring a secure hold through any course of fire. The direct-thread approach means zero additional rail or adapter length—just suppressor-on-muzzle efficiency.
If you run a PCC platform and prioritize weight and maneuverability over maximum sound reduction, the F4 delivers straightforward, no-fuss performance. Its simplicity is a feature: mount it, shoot it, clean it. For shooters wanting a bit more sound suppression in exchange for minimal added length, AB Suppressor also offers the F4L variant with additional baffles.
| Caliber | 9mm |
| Mount Type | Direct-thread, 1/2-28 |
| Weight | 4.9 oz |
| Material | Grade 5 titanium |
| Thread Pitch | 1/2-28 |
| Application | Pistol caliber carbines (PCC) |
The F4 is designed for pistol caliber carbines with 1/2-28 threaded barrels. The direct-thread mount attaches to your barrel's shoulder. Verify your specific PCC's barrel threading before purchase.
The F4L includes three additional baffles for enhanced sound suppression at the cost of roughly 1.1 inches of added length. The F4 prioritizes minimal profile and weight. Choose based on whether you value compactness or maximum noise reduction in your use case.
Yes. The fixed direct-thread mount includes wrench flats at the base, allowing you to use a tool to hand-torque the suppressor on and off your barrel shoulder without special equipment.
Titanium offers exceptional strength-to-weight ratio. The F4's Grade 5 titanium construction with circumference welding provides the durability needed for high-volume 9mm shooting while keeping total suppressor weight to a bare minimum—critical for maintaining PCC handling and balance.
