OSS 3-LUG MOUNT - Precision Quick-Detach Adapter for Suppressors and Firearms

The OSS 3-Lug Mount is a precision quick-detach adapter designed for shooters who want speed and reliability when mounting and removing suppressors on their firearms. This quick-detach mount enables fast attachment and detachment without tools, making it ideal for hunters, tactical shooters, and anyone running suppressed systems in the field. The 3-Lug interface has become a trusted standard for modular suppressor setups, and this adapter lets you integrate it with your existing hardware or upgrade your suppression system for flexibility.

Built for cross-platform compatibility, the OSS 3-Lug Mount works with 9mm fixed barrels that have a 3-Lug already installed, or attaches to aftermarket 3-Lug barrel adapters. If you're running another manufacturer's suppressor with a 1.125-28 threaded interface, this mount provides a clean way to integrate it into a 3-Lug-based system. The precision-machined construction ensures solid lockup and repeatability, which matters when you need your shots to land the same way every time.

Whether you're building a modular suppressor platform, need a reliable quick-detach solution for multiple firearms, or want to transition between fixed and quick-attach suppressor configurations, the OSS 3-Lug Mount gives you the flexibility serious shooters demand. It's the kind of accessory that pays dividends in the field or at the range when you need to swap gear fast without compromising accuracy.
