will this work for a 458 Socom?

Manufacturer Answer

Answered by Next Level Armament, Manufacturer from MI, United States, on August 05, 2026

It will work based on the internal muzzle diameter, but please check your thread size. The 11B is threaded 5/8-32 for Bear Creek barrels. The 11C is threaded 5/8-24 which is a standard thread size for 458 Socom barrels.
