Hello all, this is my first post.  I have a question about the Adams Arms upper half.  What is the difference between the Base Midlength Upper, and the Base Carbine Upper(both $599 on midwayusa.com).  I'm fixing to buy one of these and as far as I can tell from the pictures the difference is the location of the gas block.  What would be the advantage of one over the other.  I hope someone can help me out.





Thanks
