Never been gambling, but I have been told I should :).
Mine is of the Hessie type. It is hard on the brass.
Mine was purchased from SOG. Mine shot about a foot to the left and about a foot high. The magazine fits in properly and the bore is excellent.
Some of the problems I have heard about:
* Shooting to the left as much as 2 feet.
* Shooting high about a foot.
* Magazines not fitting in the gun, or having to
be smacked into place.
* The blind pin for the muzzle break
protruding into the barrel.
* Cracked, damaged stocks.
* The rear sight looks like it had been welded
on by a 10 year old.
* The charging handle being so tight it could
not be moved without extreme pressure.
That's about it off the top of my head. I got lucky, and so did my dad. If I had to do it again, I would go with a good quality FAL.
