I posted this on another thread but thought it would be better here. I don't like the plastic molded cheek piece that comes on the KRG whiskey 3 chassis. Not that there is anything particularly wrong with it other than it doesn't fit me very well and I couldn't get a good cheek weld. So what I did was ordered a piece of 1/4" abs plastic on eBay. Cost was 1.25 plus shipping, so a total of about 5.00 US. Cut out a section about 4"x6" and placed it in the oven at 350 for about 10 minutes. This rendered the abs pliable and then shaped it into a rough 90 degree angle. Run some cool water over it to set it instantly. I then used the small plastic cheek piece as a template to drill the 1/8" holes. On mine I made two rows instead of one single row. Shape the plastic on a belt sander to your liking and install. Now I have an excellent cheek weld and it changed the whole "feel" of the chassis. I angled it away from the QD cup on the rear and it doesn't get in the way of anything. All in all I am extremely pleased with it.
