The JK Armament SIG 365 Replacement Barrel (MPN JKBBLS365) is an aftermarket pistol barrel engineered for the SIG P365 handgun platform.

Listed firearm fit is Sig 365, confirming it is intended for use in the SIG P365-pattern pistol.

Sold as a single replacement barrel. Barrel dimensions as published are approximately 6.5" long in the factory packaging sleeve (barrel-only length is shorter), a width of 1.9", and a height of 0.3".
