Imperfect Mueller Dog Bone Uppers

We have some Mueller Uppers that exhibit some noticable overbite/underbite where the upper and lower mate. 

There is nothing technically wrong with these, they will function as they should, and they are still within spec. However, if you're building a clone correct rifle for display, you're likely going to want a more perfect upper. These would make an excellent candidate for a gun that is going to get used and abused and you're not worried about aesthetics. 
 
These still contain all of the other features and markings of our other Mueller M4 Dog Bones, just discounted for aesthetics.
