I am looking at stock kits for my AR and I see some listing as Mil Spec, and some as Commercial spec. Some say that mil spec receiver extensions won't fit a commercial spec receiver and Stag Arms Stock kit says that it is supplied with a mil spec receiver extensions so that it is easy for aftermarket upgrades. Basically I just want to make sure what I order will work on what I have. It is a DPMS Receiver, I am assuming it is commercial spec. However, I don't know if this matters or not but it is stamped for "Safe" "Single Shot" and "3 Shot Burst".
Also, just a quick side question. If I order a left handed upper assembly will that work on any lower receiver? Do I have to have a left handed lower receiver or are they ambidextrous? Is Stag the only ones who make the left handed uppers?
