Video from Laylax showing how to install the Nineball Umarex/VFC Glock 19X "2 Way Fixed" Non-Recoiling Outer Barrel... "Made for the UMAREX VFC Glock 19X 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.
