Get the stock away from the barrel, especially plastic. I worked on a VTR that shot terribly until I was able to chew away enough plastic AND enough heat to bend the forearm (don't ask, it was too much work and I'll never do that again ever) in a straight line with the rest of the stock.
Now it's a treasured rifle (for someone else) but before I did my voodoo, it was not a shooter at all.
