Obsidian 3 Lug Mount .45 ACP

The Rugged Suppressors Obsidian 3 Lug Mount .45 ACP is available now from LM Ironwerks, a licensed FFL/SOT dealer in Louisville, Kentucky.

This 3 Lug Mount replaces the piston assembly in your Obsidian45™, allowing you to attach the Obsidian45 to 3 lug compatible firearms. This mount is designed to be internal so that your overall firearm length is as short as possible. Using a 3 Lug Mount allows you to quickly attach/detach your suppressor to fixed barrel firearms, without having to worry about suppressor walk-off.

Note: This is the suppressor mount only. To attach, your firearm must have an integral .45ACP 3 lug* or a .45ACP 3 lug adapter.

*This is compatible with B&T .45ACP integral 3 lug firearms.

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.
