Poly Receivers Testing: Part 2

The torture continues on the TN Arms lower.  Today while the weather was nice I took a few steel casings out and induced horrible stuck cases by closing the bolt on them as well as generally beating the receiver up as much as possible.  We're talking stuck cases so bad that several of them I had to remove with a cleaning rod and a hammer, the rest I had to mortar the rifle as hard as possible on the ground to get them to budge.
