What It Does

A mount or adapter is what connects a suppressor to your firearm. It sets how the suppressor attaches (direct thread, quick-detach, 3-lug or a HUB-style system) and lets you move one suppressor between different hosts. A good mount holds the suppressor tight and centered on the bore, which is critical for safety and accuracy.

Before You Order

Check three things before you order: the thread pitch of your barrel, the mounting system your suppressor uses, and the caliber. A mount that does not match your suppressor or bore can cause a baffle strike. Install it to the manufacturer’s torque spec, and have a gunsmith check alignment if you are unsure.
