Victor, no serial number. Have a great day!

Victor, no Sir. Barrels sold separately as components do not have serial numbers engraved. Cheers and stay safe!

Usually the only time manufacturers add serial numbers to barrels is when you buy a complete firearm and they mate the barrel to the slide, so they know Wich one goes with what. This Barrel is not serialized. Hope this helps.

No barrels are not serialized, lowers or grip modules containing trigger groups or fire control units (fcu) are the only pieces requiring a serial number.
Or in some case like a sig p320 the FCU itself will be the serialized part.

no the barrel does not have a S/N
