JK Armament JKBBLS365XL 9mm Luger 1:10" 416R Stainless Black Nitride Threaded Barrel - Sig 365XL

The JK Armament JKBBLS365XL is a precision 9mm Luger threaded barrel built specifically for the Sig 365XL. Machined from 416R stainless steel with a Black Nitride finish, this drop-in barrel is engineered from the ground up for suppressor use.

Featuring a 1:10" twist and a ramped breech for reliable cycling, the JKBBLS365XL gives Sig 365XL owners a rugged, threaded platform ready to host a compensator or suppressor. The corrosion-resistant Black Nitride coating complements the precision 416R stainless construction, making this a direct upgrade path for an already popular concealed-carry and duty pistol.
