Atlas Custom Works Silencer Adapter Kit for AAP-01 GBB Pistol, Black

The Action Army AAP-01 is a solid GBB pistol, but the factory barrel doesn't give you a clean way to mount a suppressor or mock suppressor. That's where this Atlas Custom Works adapter comes in.

What it does. This barrel adapter threads onto the AAP-01's existing barrel and provides a standard 14mm negative (CCW) thread at the muzzle. That's the airsoft standard for suppressors, flash hiders, and compensators. Once installed, you can screw on any muzzle device that matches that thread pattern.

Fit and finish. Machined from aluminum, so it's light and won't add noticeable weight to the pistol. The adapter replaces the factory barrel tip, and the black finish matches the AAP-01's standard color scheme.

Before you buy. This is just the adapter. You'll need to source your own suppressor or mock suppressor separately. The AAP-01 is a gas blowback pistol, so make sure any suppressor you choose is rated for GBB use — full-power airgun suppressors can be overbuilt and add unnecessary length.

Installation requires basic hand tools and a bit of patience. If you're not comfortable working on your gun's internals, have a tech handle it.
