Army Armament Threaded Outer Barrel for R601 JW3 GBB Pistol - 12mm CW Female

Army Armament
Code: R601-BARREL A-245
  • Alloy construction
  • 12mm CW female threads
  • For Army Armament R601 and Hi-capa GBBs

This outer barrel is a replacement original part for the Army Armament R601 JW3 GBB pistol but should also be compatible with other Army Armament Hi-capas and 1911 GBB pistols. The barrel is constructed from alloy and comes with 12mm CW female threads at the tip, leaving options open for adding a tracer unit or suppressor using a 14mm CCW male thread adapter (available separately). The barrel may also be suitable for other Hi-capa and 1911 pistols based on the original TM design but may require modifications to be made for smooth function.

The barrel is finished in bronze and has authentic looking mock locking lugs across its upper surface, with "9x19" marked on the chamber area in recessed lettering. The barrel has a standard flared profile which tapers towards the chamber, matching the more common real steel Hi-capa barrels perfectly.
