Armory Craft SIG P320 X-Five & X5 Legion 5.7" BULL Barrel - THREADED - BLACK

1/2 X 28 RH - 9MM


FINISH: Black nitride / QPQ


Not for X-CARRY Legion, which uses a regular (non-bull) P320 Compact threaded barrel. Only for Sig X-Five/X-Five Legion, not for other regular non-X5 P320 models or AXG models.


- X5 Threaded Bull Barrel WITH a stainless thread protector included.


Important - Please Read All Details Below:


- This barrel does NOT have an LCI (loaded chamber indicator), which is the preferred version when shooting a firearm with an optic.


  • 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.


  • 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.
