ATI GER4110112 GSG 1911 Silencer Adapter - 1/2"-28 TPI Steel, Black Finish

If you're running a GSG M1911 or GSG 522PK with a threaded barrel, you've probably noticed they don't play nicely with standard suppressors. The ATI GER4110112 GSG 1911 Silencer Adapter solves that problem by converting your firearm's metric threading to the universal 1/2"-28 TPI standard. This steel adapter lets you mount any standard 1/2"-28 suppressor to your GSG platform, opening up your sound-reduction options without requiring a barrel swap. It's a straightforward, affordable solution for shooters who want to run suppressors on these popular rimfire platforms.

Built from solid steel and finished in matte black, this adapter is made to last. The metric-to-standard thread conversion is precise, so your suppressor will mount securely and concentrically. Whether you're shooting suppressed at the range or in the field, this adapter bridges the compatibility gap between GSG's metric threading and the aftermarket suppressor ecosystem.

Installation is simple—just thread it onto your existing GSG barrel and you're ready to attach a standard 1/2"-28 suppressor. If you've already invested in a quality suppressor or plan to use one across multiple firearms, this adapter pays for itself in versatility.
