I was really hesitant to cut the stock on mine, figuring I would mess it up. Eventually, I just went slow and everything worked out great. I am not a woodworker either, by any stretch of the imagination.

I cut the bulk, of the stock off with a saw, then started to slowly whittle the remaining stock into the shape I wanted. Once I got close enough that I was scared I'd take too much off with the knife, I switched to a coarse sandpaper and started the final shaping. This took a long time, because I stopped whittling with so much left on it. Once the shape was close, I switched to finer sandpapers.

I scuff the foregrip, the stained both to match and used a spray clear as the finish. I was very happy with the results.
