SilencerCo® Low Profile 3-Lug Mount – .45 ACP – AC2448
The SilencerCo AC2448 is the 2026 definitive solution for shooters seeking a compact, lightning-fast mounting interface for .45 caliber pistol-caliber carbines (PCCs) and submachine guns. While 3-lug systems were traditionally limited to 9mm platforms, this .45 ACP specific mount brings the legendary "push-and-twist" functionality to heavy-hitting platforms like the B&T APC45, KRISS Vector, and custom .45 ACP AR builds. By utilizing the Low Profile architecture, the AC2448 reduces the overall footprint of your suppressed system by nearly an inch compared to older legacy mounts, ensuring your weapon remains balanced and maneuverable in close-quarters environments.
Precision-machined from high-strength stainless steel with a non-reflective matte black finish, the AC2448 (816413023778) is built to withstand the increased gas volume and pressures of .45 caliber projectiles. It is natively compatible with SilencerCo’s heavy-duty pistol suppressors, including the Omega 45K and the Octane 45 series. It also serves as a critical component for multi-caliber silencers like the Hybrid 46 and 46M when paired with the correct adapter. Note: Because .45 3-lug dimensions differ from 9mm standards, this mount requires a compatible .45 ACP 3-lug muzzle device. For the 2026 tactical professional, the AC2448 represents the peak of reliability and speed for large-bore suppressed platforms.
Includes: (1) SilencerCo Low Profile .45 ACP 3-Lug Mount and (1) Spanning Wrench for secure installation.
