That rifle was my first build. It is in .50cal. 42" straight barrel. I love it. I might suggest paying the extra money for the swamped barrel if you are going to hunt it however. It is very accurate and their kits go together very well. Matt and Toni are great to work with and will always answer your questions. I have not posted a picture here before but I guess it's time to give it a try. I also went up 1 grade of wood on mine. I would not do that again for a first build. You WILL build more! Good luck, Bob
