TTI - WE/TM Gen3 G17/G18c G-Series Fixed Outer Barrel Type B - Gold

TTI G-Series fixed outer barrel, Type B, in Gold.

A CNC machined replacement outer barrel for WE and Tokyo Marui Gen3 G17 and G18c gas blowback pistols. The tighter fit into the slide steadies the barrel-to-slide relationship, which usually shows up as better grouping on a gun that has loosened off with use.

Type B has internal 11mm CW threads, so you will need an 11mm-to-14mm adapter to fit most tracer units and suppressors. Type A is the same barrel with 14mm CCW external threads and a cap, and is listed separately — the thread is the only difference, so check which one your muzzle device needs.

Fitting is straightforward but does mean stripping the slide; if you have not done that before it is worth having someone who has.
