I always enjoy seeing people's work on firearms and you definitely did a good job. However, it seems a useless idea, except from the can I do this standpoint. Two shots and you're done. Where's the actual tactical application of that?
I am not questioning your skills, just the practicality of the effort.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
