Luth-AR 223 Buffer Body Carbine. We wanted to make something that looks like a bolt-action rifle but was an AR buffer tube. We were able to take one of our most popular AR buffer tube sizes and make it look like two different rifles. The end result a very cool looking rifle that we are all proud to call our own. Look at the beautiful detail on this rifle and imagine making it even better with one of our great long tubes. Not only is this a great looker but by the end of the AR by Luth-AR you will have created one very unique rifle indeed.
