SilencerCo Alpha Direct Thread Mount M18x1 Matte Black - SKU: AC837 - UPC: 817272011890
Product Description
The SilencerCo Alpha Direct Thread Mount (AC837) is a precision-machined adapter designed to attach Alpha-compatible suppressors directly to host firearms featuring M18x1 barrel threads. By eliminating the need for a quick-detach muzzle device, this direct thread solution reduces overall system length, lowers total front-end mass, and maximizes concentricity between the suppressor bore and the barrel axis to eliminate bullet strike hazards.
Engineered from high-strength stainless steel and coated in a durable matte black finish, the AC837 mount stands up to extreme heat, pressure, and carbon fouling without thread degradation. It is fully compatible with SilencerCo’s Alpha housing interface platforms—including the Omega 9K, Omega 45K, Octane series, and Harvester 300—providing a rigid, reliable interface for heavy firing schedules across pistol, pistol-caliber carbine (PCC), and precision rifle platforms.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: SilencerCo Alpha pattern suppressors (Omega 9K, Omega 45K, Octane series, Harvester 300) to M18x1 threaded barrels.
- Ensure the host firearm is unloaded, magazine removed, and chamber confirmed empty.
- Clean host barrel threads (M18x1) thoroughly to remove any rust, carbon, or thread sealant residue.
- Thread the AC837 Alpha mount directly into the rear housing of the Alpha suppressor by hand until fully seated.
- Torque the mount into the suppressor body using the appropriate SilencerCo spanner wrench according to manufacturer specifications.
- Thread the suppressor assembly onto the barrel shoulder until hand-tight, and verify bore concentricity using an alignment rod prior to firing.
Key Features
- Direct Thread Efficiency: Converts Alpha pattern suppressors to direct thread attachment, minimizing added length and overall system weight.
- High concentricity Alignment: Ensures precise alignment between the barrel bore and suppressor baffles to prevent baffle strikes.
- Durable Steel Construction: Machined from solid stainless steel to withstand sustained thermal cycling and chemical exposure.
- Matte Black Finish: Non-reflective finish matches tactical finishes and protects against surface corrosion.
- Alpha Platform Versatility: Seamlessly integrates with SilencerCo Omega 9K, Omega 45K, Octane series, and Harvester 300 silencers.
