A precision upgrade for your Glock GBB

Transform your Umarex or VFC Glock 19 or 19X with this Laylax Nine Ball 6.00mm tight bore power barrel. Measuring 85mm and machined to a tight 6.00mm bore, it drops straight in to replace the stock inner barrel and immediately lifts the consistency and accuracy of your gas blowback pistol.

Tighter seal, more range

The reduced 6.00mm inner diameter tightens the air seal behind each BB, so more of the gas charge drives the shot. The payoff is flatter, more repeatable groups, improved effective range and often a small FPS gain, giving you the edge on game day.

Built to last

Where many barrels use brass, this Nine Ball barrel is made from stainless steel that is harder and far more durable. An internally polished bore and precision crown release each BB cleanly for a stable, predictable flight path, and hold that precision shot after shot.

Get the most from it

Pair the barrel with a quality hop-up bucking for the best air seal and hop consistency. Fitting is a simple slide-in job during a normal pistol strip. Explore more upgrade parts in our airsoft accessories range, or let our Kent airsoft workshop fit and tune it for you.

Frequently asked questions

Which pistols does this barrel fit?

It is designed for the Umarex and VFC Glock 19 and 19X gas blowback pistols. The 85mm length and Glock GBB profile make it a direct drop-in replacement for the stock inner barrel.

What does a tight bore barrel actually do?

A 6.00mm bore is tighter than a standard barrel, so it improves the air seal behind the BB. That gives you more consistent shots, better accuracy and a useful gain in effective range, sometimes with a small FPS increase.

Why stainless steel rather than brass?

Stainless steel is harder and more durable than the brass used in many barrels, so it resists wear and holds its precise bore over time for lasting performance.

Do I need anything else to fit it?

For best results pair the barrel with a quality hop-up bucking. The barrel handles air seal and precision, while a fresh bucking optimises hop and consistency. Fitting is a straightforward slide-in during a standard pistol strip.

Can you fit it for me?

Yes. If you would rather not strip your pistol, our in-house Kent workshop can install the barrel and tune the hop for you. See our airsoft repair and servicing page for details.
