"Morpheus" Dual Bore AAP-01 Barrel 129MM

We used the more durable and stronger SUS304 seamless Steel because we wanted to step up the game a bit. Most brands use SUS303 seamed steel because it's easier to machine. SUS303 stainless steel's corrosion resistance is weakened due to its composition as it's specialized for machinability so the SUS304 steel we use is harder to machine but more durable and has wonderful corrosion resistance.

This barrel has an enlarged, unbridged window and is specially made for the action army AAP-01 pistol. This barrel ensures that the bucking and barrel combination fits perfectly in your hopup.
