Original Design: GSI’s Non-Tilting Barrel (NTB) is the original fixed-barrel system, patented and sold since 2015.
-
Efficiency: The non-tilting structure eliminates interference between the slide and barrel, resulting in faster cycle speeds and higher gas efficiency.
-
Compatibility: The fixed design allows for the attachment of suppressors or tracer units without affecting the slide’s movement.
-
Stability: An internal rubber O-ring ensures the inner barrel remains centered and stable across various brands.
-
Convenience: The 14mm CCW (Counter-Clockwise) adapter can be tightened or loosened using a coin.
-
Enhancement: The design supports inner barrel extensions for improved muzzle velocity and accuracy.
