We use Mid State Firearms for our AR builds and I saw they have a non-reciprocating side charge upper. If that upper is what I think it is then that is a left handers(me) dream come true. You still can pull the bolt back and lock it in place, correct? All that is missing is the t handle thing on the top inside of upper? This sounds to good to be true if I know anything (which might not be much)! I love Mid States Firearms promptness and quality not to mention prices. I absolutely cannot believe I got hooked on these darn black stuff at my age!!
