that stock has some decent figure in it. i have mine set up in a delux sporter stock too. mine sports a 20" GM sporter barrel.
I know you are replying to the OP, but I have to say one of my buddies has a GM sporter barrel on his and that is a shooting sob. At first glance, it looks like a regular ol Ruger 10-22 barrel with no sights, but damn is it a good shooter. It's a lot less finicky than my factory target barreled 10-22 too.
I have a question for the OP:
How does that baby shoot. I know you said it's a shooter, but come on now? Any targets to post? I know wareagle likes posting target pics in the AR forum. Rifle looks great!! Thanks...
