Product Overview
The Rugged Suppressors Fixed Mount 1/2X28 is a precision-engineered mounting accessory designed for shooters who demand a simple, secure, and reliable interface for their suppressor on fixed-barrel firearms. This product is engineered specifically to replace the booster (piston) assembly in Rugged Obsidian 45 and Obsidian 9 suppressors when used on platforms where barrel movement is not required for operation. It is the ideal solution for enthusiasts and professionals utilizing carbine, pistol-caliber carbine (PCC), or submachine gun platforms. By converting your Obsidian can to a fixed-mount configuration, you eliminate unnecessary complexity, ensuring a solid and consistent attachment that enhances accuracy and long-term durability. This mount is a practical, performance-focused upgrade for anyone seeking to optimize their suppressor for dedicated fixed-barrel use.
Key Features
- Precision 1/2X28 Thread Pitch: The industry-standard thread pattern for countless 9mm and .223/5.56mm fixed barrels, ensuring broad compatibility with popular carbine and subgun platforms.
- Direct Booster Replacement: Seamlessly replaces the factory booster assembly in your Rugged Obsidian 45 or Obsidian 9 suppressor, converting it from a tilting-barrel pistol host to a dedicated fixed-barrel system.
- Secure, Non-Moving Interface: Engineered without the spring mechanism of a piston, this fixed mount provides a rigid and repeatable attachment point, which can contribute to improved point-of-impact consistency and suppressor alignment.
- Enhanced Durability & Simplicity: With fewer moving parts than a booster system, the fixed mount reduces potential wear points and maintenance requirements, offering a straightforward “set it and forget it” mounting solution.
- Optimized for High-Volume Fire: Built to handle the thermal and mechanical stresses of semi-automatic and automatic fire on carbine and submachine gun platforms, where a booster is neither needed nor desirable.
- Rugged Suppressors Quality: Manufactured from high-grade materials and built to the same exacting standards as the suppressors themselves, guaranteeing a perfect fit and long-term reliability.
Performance & Applications
This Fixed Mount 1/2X28 unlocks the full potential of your Obsidian suppressor on non-tilting-barrel firearms. Its application is specific and performance-oriented, catering to setups where reliability and a solid lockup are paramount.
Pistol-Caliber Carbine (PCC) Platforms: For 9mm AR-style rifles, CZ Scorpions, or similar PCCs, this mount is the correct choice. It allows your Obsidian 9 to function as a dedicated, rigid muzzle device, perfectly suited for competition, training, or recreational shooting. The fixed interface ensures the suppressor remains concentric and stable shot after shot, which is critical for safety and accuracy during rapid strings of fire common in PCC use.
Subgun & Dedicated SBR Hosts: When mounting an Obsidian 45 on a fixed-barrel 9mm or .45 ACP submachine gun or short-barreled rifle (SBR), the booster system is obsolete. The Fixed Mount provides the secure, rigid attachment these platforms require, handling the increased rate of fire and operational demands without the unnecessary complexity and potential failure points of a moving piston.
Rimfire Applications with Fixed Barrels: While primarily for centerfire, this mount can also be utilized on certain fixed-barrel .22 LR hosts compatible with the 1/2X28 thread pitch and when using the Obsidian 9 in its appropriate configuration. It offers a simple, direct-thread alternative for a lightweight and quiet rimfire setup, always confirming compatibility with your specific host firearm first.

I’ve been shooting for 5 years and I’m picky about where I buy accessories online. Brown’s Firearms earned my business. The Rugged Suppressors Fixed Mount 1/2X28 arrived in 3 days, packaged well, and fit my G22 without any modification. I put 185 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.

Bought this as part of a larger build project. Brown’s Firearms had the best price by a decent margin and shipping was fast. The Rugged Suppressors Fixed Mount 1/2X28 itself is well-made — Tight tolerances. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
