The Atlas Custom Works AAP-01 Aluminum Outer Barrel Type A swaps out the factory barrel for something that looks the part and holds up to regular use. At 60 grams in aluminum, it adds a bit of heft to the front end while giving the AAP-01 a more finished, custom appearance.
What it changes. This is a Type A profile, so it matches the original barrel length and contour of the Action Army AAP-01 GBB pistol. You're not changing the inner barrel or the shot profile — just the external look and the feel of the front end. Gold finish on aluminum makes it stand out from the usual black or silver options.
What you need to know. This fits the Action Army AAP-01 GBB pistol only. Outer barrels don't affect velocity or range — those come from the inner barrel and hop-up. If you're after a visual upgrade that still looks like a proper barrel, this does the job without messing with the gun's function.
Includes the outer barrel only.
