Description
Pistol boosters are great on tilting barrel handguns, but they have no business on a fixed barrel gun. That's exactly why Rugged Suppressors makes the Fixed Mount. This little piece of hardware swaps in place of the booster system on your Obsidian 45 or Obsidian 9, turning your pistol can into a proper fixed mount setup for carbines and subguns with 9/16×24 muzzle threads. No piston movement, no unnecessary parts cycling, just a direct thread connection between your suppressor and your host.
Why the Rugged Fixed Mount Beats Running a Booster
When you thread a booster equipped can onto a fixed barrel firearm without the proper spacer or mount, you're asking for reliability headaches and unnecessary wear. The Fixed Mount solves that by removing the booster from the equation entirely. The result is a more rigid connection, consistent alignment shot after shot, and one less moving part to think about. It installs quickly, so switching your Obsidian between pistol duty and carbine duty takes just a couple minutes at the bench. The black finish keeps things low profile and matches the Obsidian's look so the whole package stays clean.
Setting Up Your Obsidian 45/9 Fixed Mount
A couple things worth knowing before you order. This mount is a standalone accessory, meaning it does its job on its own and is not meant to be combined with Rugged's 3 Lug Mount or the Fixed Barrel Spacer. Those are separate solutions for separate setups. Also, double check the muzzle threads on your host gun, because this version is cut specifically for 9/16×24, a thread pitch you'll commonly find on .45 caliber carbines and subguns. Rugged offers the Fixed Mount in several other thread pitches, so if your barrel is threaded differently, grab the matching version instead.
If you bought an Obsidian for your pistol but keep eyeing that fixed barrel carbine in the safe, this is the piece that lets one suppressor pull double duty. Simple, solid, and built by the same folks who made your can.

Frequently Asked Questions
Which suppressors does the Rugged Fixed Mount 9/16×24 work with?
It's built specifically for the Rugged Obsidian 45 and Obsidian 9. The mount threads into the suppressor in place of the factory booster assembly, converting the can from a pistol configuration to a fixed mount configuration for fixed barrel hosts.
Can I use this with the 3 Lug Mount or Fixed Barrel Spacer?
No, and you won't need to. The Fixed Mount is a standalone accessory that fully replaces the booster system on its own. The 3 Lug Mount and Fixed Barrel Spacer are separate mounting solutions for different setups, so pick the one that fits how you plan to run your can.
What firearms typically have 9/16×24 muzzle threads?
The 9/16×24 pitch shows up most often on .45 caliber carbines and subguns with fixed barrels. Always verify the actual thread pitch stamped or listed for your specific barrel before ordering, since Rugged makes this mount in several thread options and you want the one that matches your host exactly.
Why can't I just run my Obsidian with the booster on a fixed barrel gun?
Boosters exist to help tilting barrel pistols cycle under the weight of a suppressor. On a fixed barrel, that movement serves no purpose and can cause wear and inconsistent lockup. Swapping in the Fixed Mount gives you a rigid, direct thread connection that's better suited to carbine and subgun use.
