  •  Sorry, NO COUPONS can be used for this the barrel or the combo package
  • No International Shipping

  • This is a 'drop-in' barrel. Fitting is not required.
  • Matches or exceeds the fit of SIG factory X5 barrels
  • This is a thicker (16mm) bull barrel which comes only with X5 pistols, that is necked-down to 14mm once it leaves the slide. This 14mm is the same thickness as 'regular P320 threaded barrels'. This will ensure compatibility with any silencers, Armory Craft compensators and the vast majority of other P320 compensators currently on the market.
  • CNC machined out of a solid billet of 416R Stainless Steel. 416R is a hardened chromium stainless steel particularly suited for use in high quality precision barrels. This grade has good machinability and, because of closely controlled chemistry and processing techniques, may be machined and lapped to a high finish, which is important for bore accuracy.
  • You can purchase 'only the barrel' which will come with a stainless steel thread protector or a discounted 'compensator combo package' with Armory Craft steel/black nitride compensator, for which the thread protector will have to be purchased separately. 
  • Lenght: 5.7"
  • Material is Hardened Stainless steel in Matte finish
  • Manufactured by a well known US OEM barrel manufacturer in a facility which is certified to ISO 9001/AS9100 & in accordance with the requirements of AS9104A. 


We also offer compensators for P365 Pistols. Please CLICK HERE as well as compensators for P226, P229 and P320 compensators that can be purchased separately - please CLICK HERE.
