Home about a year and half maybe two years ago now. I bought that way before buying any other parts and then I bought mags. The last part I bought was the full upper.
I did get to shoot it and it worked great. The only problem I have with it is the bolt release isnt working. I think it has to much finish on the receiver or the part it self. I remember when I put it in the reciever it was really tight. I will get that fixed then its 100%.
Also no jams with it using wolf ammo.
