Nineball Elite Force Glock 17 Fixed Threaded Outer Barrel

UMAREX GLOCK17 "2 Way Fixed" Non-Recoiling Outer Barrel ●14mm CCW Threaded Muzzle Cap.●Lightweight, precision machined aluminum. Made for the UMAREX GLOCK17 gas blowback series. The combination of set grub screws and high strength aluminum alloy outer barrel make for a highly stable shooting platform. Choose between a non-threaded outer barrel cap for normal use, or a 14mm CCW threaded muzzle cap for infinite attachments. The outer barrel is also negatively threaded so 11mm positive threaded attachments can slide right in!  "Non-recoiling" - What does it mean?The non-recoiling outer barrel sets the inner barrel using 2 grub screws in order to fix the outer and inner barrels together. This creates a stable firing platform and reducing all movement between the outer barrel and slide. Consistent performance, stable accuracy and velocity.  ■Brand: Nine Ball ■Included:・Metal Outer Barrel ×1・Normal Muzzle Cap ×1・SAS 14mm CCW Threaded Cap ×1・Hex Grub Screw ×1 ■Compatibility: UMAREX VFC GBB
