I like it. I'm not prejudiced against synthetic stocks, but the Avenger's is particularly cheesy. The wooden stock looks a lot better, and the the extra weight makes it shoot a little better for me.
The seller (Pyramid} didn't throw screws in with the stock. If the screws aren't in the box you will need:
1 M5 x 40mm socket cap screw
1 M3 x 16mm flat head hex socket screw
The wooden stock is a little bigger than the plastic stock, and the original screws are a little too short to engage the screw holes.
