Hadron Airsoft Designs presents "THOR".. The Hammer Of Rotary..

Simple and effective, this is a tricky part to fit, and should not be attempted without research.

Perfect diameter for the AAP-01 with minimal bolt forward resistance.

This part requires slight modification and tuning of the hammer group, and special attention to the auto sear.

This part should fit all G derivative airsoft RIF including the WE Galaxy.

Only 1 bearing supplied, not 2 as pictured.
