Left hand upper receiver
If you're left handed, this beats using right handed tools.

Nice so far
I got this to build a left handed ar. So far I really like it. Have not been to the range as yet but the black rain bcg works fine in it. Fits better on my 5.56 lower than the new lower. Nice and tight no rattles. My only complaint is I didnt order 2.

Left hand upper receiver
Stag Arms makes a great product. Along with their left hand bolt carrier group, I was able to assemble a fine lefty rifle. The best price, and fast service is why they get a 5 star from me.

A3 Left hand Flattop Receiver
If you’re a left hand shooter, this is a must have. This is my 3rd purchase from Stagarms. The only problem I’m encountering is my ejection port cover rod keeps coming loose after 7-10 rounds. I continually have to push it back into place otherwise it will come out.
