The SilencerCo AC2602 is a 3-lug muzzle device designed for 9mm firearms with M13.5×1 left-hand threads. This adapter serves as a mounting interface for SilencerCo suppressors and other 3-lug compatible sound suppressors, allowing shooters to quickly attach and detach their silencer while maintaining a consistent point of aim. The 3-lug design is a proven standard in the suppressor world, offering fast installation and removal without tools—a genuine convenience factor if you're running your 9mm between suppressed and unsuppressed configurations or swapping gear between firearms.

The AC2602 is built for 9mm platforms that use the M13.5×1 left-hand thread specification, which is common on certain pistol-caliber uppers and dedicated 9mm barrels. Left-hand threading prevents accidental loosening during firing and requires a barrel already cut to these exact specifications. Before ordering, verify that your barrel or upper receiver is threaded to match—this is not a universal adapter and won't fit standard right-hand or different-diameter threads.

As a component part, this muzzle device integrates into a suppressor setup, not as a standalone sound-reduction tool. It's an essential piece if you're building or upgrading a 3-lug-compatible suppressor platform. SilencerCo's reputation for precision manufacturing means tight tolerances and reliable indexing, which matters when you're counting on repeatability across multiple mounting cycles.
