Kross Airsoft Design Glock TDC Outer Barrel Kit V2

The Glock TDC kit was one of KAD's most-asked-after products during its V1 run — and V2 brings it back with refinements. Compatible with the Tokyo Marui Glock 17 Gen 3 and Tokyo Marui Glock 18, the kit gives you a threaded outer barrel suitable for tracer units, mock suppressors, or full-size silencers.

TDC architecture lines up the inner barrel along the optical centre of the bore rather than letting it float, which is the single biggest factor in shot-to-shot consistency on a gas blowback pistol. Combined with a fresh bucking and a properly broken-in mag, you should notice a meaningful improvement in your hit rate at the 20–35m bracket — the range where Glocks usually start to scatter.

Glock 17 vs Glock 18 fitment

The same kit fits both donors because the TM 17 Gen 3 and TM 18 share their slide and barrel architecture. Worth knowing: the Glock 18 already cycles aggressively in full-auto, and a TDC kit doesn't change cyclic rate — but it does mean the auto-fire bursts land closer together, which is the whole point of running a select-fire pistol in skirmish.
