Atlas Custom Works Threaded Aluminum Alloy Outer Barrel for G17 GBB Pistols, Gold

The Atlas Custom Works threaded outer barrel gives your G17 GBB a clean, finished look and opens the door to muzzle devices. Most players add a suppressor, flash hider, or tracer unit for realism or function—and you can't mount any of those without threading. This barrel provides it.

What changes. The outer barrel is purely cosmetic and functional for mounting. It does not affect velocity, range, or accuracy—those come from your inner barrel, hop-up, and air seal. What you get is a threaded muzzle that accepts standard 14mm CCW accessories and a gold finish that stands out from the usual black or OD Green.

Material and fit. Built from aluminum alloy, it's light and corrosion-resistant. Atlas Custom Works is a known aftermarket brand in the Glock platform space, so machining and threading should be clean.

Before you buy. Check two things: first, confirm the thread pitch matches your intended muzzle device (14mm CCW is the airsoft standard, but verify); second, measure your current outer barrel length or compare it to the product's dimensions if listed. A barrel that's too long will protrude past the slide and look wrong; too short and your suppressor may not seat properly. This fits most G17 GBB pistols, but G18C or aftermarket slide assemblies can have different clearances.

Includes the outer barrel only—no muzzle device, no inner barrel, and no mounting hardware beyond what's threaded into the barrel itself.
