Nice idea but the weight and force exerted by an AR15 with totally destroy that thing. Might work for a paintball gun though.

Someones been watching Sons of Guns too much! They did exactly what you are talking about in an episode.

 

See the MB with the 30 cal ? All military vehicles in civilian ownership came within a hair of being recalled and de-milled , not once, but twice! This rider was attached to a bill -one of those "midnite specials" and would have required owners to turn in military vehicles to be destroyed. The War Bird guys got wind of it,and it was taken out. Now we (MVPA) have a lobbyist to watch for this crap. How ever, it shows the Liberal mindset ....
