NOT MY GUNS!

As my dad used to say about guns like this. "Kills in front, cripples behind" At least, you HOPE it kills in front.
And there are dozens more like this all over the net... You
got ripped off for paid how much?
Seriously. Kidding around aside, there is a good bit about these guns having issues not supporting cases where the feed ramp is at. Leads to the pictures shown, and much pain from the shooter. Just a word of caution. Take it for what you want.
One guy "second picture" said he was in the hospital for a while with a "hamburger hand". LOTS of stitches later, he'll be "shooting left handed only from now on".

Not dissing your gun! I'm just saying...
Honestly hope you have great success with your gun. Good luck.
This was pretty fun 
, but nobody else is learning anything or benefiting from tit for tat (learning from others is what these forums are really supposed to be all about. IMO), so I've said enough and wont say anymore on the whole thing. Enjoy your new shooter!
