I hadn't thought of that.  Is MEK used in solvents?  I should think since 
plastics have been used in guns for a while now (Glock 17, etc.) they should 
have found formulas that won't melt.

I would have preferred aluminum like the original.
On the other hand, it shot pretty well when I tested it.  The AR-7, by its 
very nature, is not intended to be a heavy-duty rifle.  It's lightweight and 
cheap; if you break it, you can buy another one.
