More than simple re-cores, the folks at Curtis Tactical can jailbreak your sealed silencer to make it user-serviceable and also replace or convert entire mounting systems. While we’re sure Curtis Tactical would like you to change to their mounting system, importantly they can convert silencers with legacy mounting systems to the now-universal 1.375×24 TPI HUB mount. There are literally dozens of companies making silencers, mounts, and devices for the HUB mount.
