For the record, 'action' should not be interpreted as 'semi-automatic, automatic, or three shot burst'. 'Action' refers to how the rounds are cycled within the gun. Single-action, for instance, means the hammer must be roostered manually before firing. Double action, on the other hand, is when the gun automatically primes the hammer with each shot. Action may also refer to bolt-action, slide, gas-operated, etc. In the future, please do not confuse action with rate of fire.
Now that my rant is finished, I have to say this is a very impressive weapon for Blockheads. Congratulations. Plus one virtual cookie
