Hello, this is not my gun by the way, just to let everyone know. But I know some1 who has an AR-15 and it was a kit gun (had everything but stripped lower). But it said "All semi auto lower receiver parts are INCLUDED as well as semi auto bolt, carrier, and charging handle. The upper is COMPLETELY ASSEMBLED. Each and every part to the gun is included EXCEPT the stripped lower receiver!" And I promise you we have not altered the gun IN ANY WAY WHATSOEVER So would any of you have an idea or clue as to what may be malfunctioning? What would be needed to fix/change to make this be SA like it was meant to be? Thanks for any help you guys may give me, it is much appreciated.
P.S. You don't have to worry about me or anyone I know possibly "reverse engineering" your info in an attempt to illegally alter the gun to make it FA. Like I said before it is already full auto lol. But honestly we're just trying to fix it, not sure what went wrong. And honestly, if we were intending to illegally modify a gun, I can assure you we would not post something on a forum for an answer, we would probly just search online, there is a lot more information on changing a SA to a FA other than FA to SA.
