Sig Sauer MCX/M400 Taper Cap 5.56 NATO Black TAPER-CAP-556

The SilencerCo Harvester Thread Mount (AC731) is a precision-machined direct-thread adapter designed to attach compatible SilencerCo suppressors to firearms with a 1/2×32 thread pitch. As part of SilencerCos Alpha mounting system, it allows users to configure their suppressor for use across multiple platforms by swapping thread mounts to match specific barrel threading.

Constructed for durability and consistent alignment, this mount offers a secure, repeatable connection without the added weight or complexity of quick-detach systems. Its low-profile, flush-fitting design helps minimize overall suppressor length, creating a more compact and streamlined setup.

Designed specifically for fixed-barrel firearms such as rifles and pistol caliber carbines, the AC731 provides a reliable and straightforward mounting solution. It is not intended for use on tilting-barrel pistols, ensuring optimal performance and longevity when used in the appropriate applications.
