Outer Barrel Extension for AAP-01 / AAP-01C by Action Army
This stylish and functional barrel extension is designed for AAP-01 and AAP-01C gas pistols. Thanks to the standard 14mm CCW thread, it can be mounted on any airsoft replica with the same thread, though it fits the AAP-01 lineup perfectly. In some cases, using an O-ring or thread spacer might be needed for perfect alignment.Its 70 mm length allows you to install longer inner barrels up to 186 mm (e.g. part D01-045), giving you better accuracy and potentially higher performance. The CNC-machined 6061 aluminum body ensures lightweight and strength, and the anodized surface adds a unique look to your pistol. Best used in combination with the M-LOK handguard and folding stock for a distinctive tactical setup.
