Man, if I were local, I'd be scouring every trash receptacle I could find for those.
The sights and selectors alone could be worth a few hundred to over $1000. Not to mention whatever else could be salvaged out of the pieces. And if the foreends could have been saved...wow. Not to mention surviving bolts, locking pieces, etc. if any made it.
I thought MG receivers were supposed to be torch cut?
