Thank you this is my first attempt at something like this. Yes, I just filled the sling hole and finished Sanding. The comb? Is that the area with the groove and recoil lug? I would like to extend the pistol grip but I'm not quite sure how or what to use to do it. I have started shaving it in at the top. I don't have big kossack hands so I also was basing that area off of my Remington. I appreciate the comments and welcome any and all advice.
