SilencerCo AC2448 Low Profile .45 ACP 3-Lug Mount for Omega 45K - SKU: AC2448 - UPC: 816413023778
Product Description
The SilencerCo AC2448 is a low-profile .45 ACP 3-lug mount adapter engineered to convert Alpha-pattern suppressors—specifically the SilencerCo Omega 45K and Octane 45 series—into a rapid-detach QD mounting platform. Designed for submachine guns, pistol-caliber carbines (PCCs), and large-format pistols chambered in .45 ACP, this mounting assembly interface connects directly onto 3-lug barrel adapters or integrated 3-lug muzzle devices without increasing overall system length unnecessarily.
Precision-machined from stainless steel and treated with a durable black oxide finish, the AC2448 features an internal spring-loaded retention piston that provides positive, repeatable locking alignment. The low-profile housing sits largely recessed inside the rear tube assembly of compatible suppressors, preserving clean aesthetics and compact host geometry while eliminating thread unthreading issues associated with standard direct-thread mounts during sustained rapid fire.
Engineered to handle the increased bore clearance demands of .45 ACP projectiles, the AC2448 ensures concentric bore alignment to prevent baffle strike risks across pistol-caliber platform builds.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: SilencerCo Omega 45K, Octane 45, Octane 45K, and Alpha-pattern rear thread suppressor housings. Connects to standard .45 ACP 3-lug male barrel adapters.
- Verify host firearm is completely clear, magazine removed, and chamber physically confirmed empty before servicing.
- Unscrew and remove existing direct-thread housing or piston retainer assembly from the rear of the suppressor tube.
- Apply a thin layer of high-temperature anti-seize grease to the male Alpha threads of the AC2448 mount assembly.
- Thread the AC2448 3-lug mount into the rear of the suppressor housing and torque to 25-30 ft-lbs using the appropriate hook spanner tool.
- Align suppressor over the male 3-lug barrel adapter, push forward against internal spring tension, rotate 90 degrees until indexed, and release to lock into place. Verify firm spring engagement prior to live fire.
Key Features
- Rapid 3-Lug Attachment: Delivers instantaneous push-and-twist mounting onto .45 ACP 3-lug barrel devices without tools.
- Low-Profile Recessed Geometry: Streamlined design minimizes overall suppressor length addition and keeps system weight balanced.
- Internal Spring Retention: High-tensile internal spring keeps constant locking pressure against 3-lug stops to eliminate looseness.
- Durable Stainless Steel Build: Heat-treated stainless steel construction with black oxide finish stands up to aggressive thermal cycling.
- Caliber-Specific .45 ACP Bore Clearance: Built specifically for .45 ACP platforms to ensure maximum coaxial alignment safety.
