M16A2 Receiver pin problem...
 

Well, don't ask me how, but one of the pins that keep my upper and lower receiver together has "gone missing" and my gun is falling apart.

Does anyone know where I can get a replacement pin?

I have the Guarder set and it works great.

which pin is it? i have the TM front receiver pin for sale. the rear one is somewhere in my basement, ive looked for along time and havnt had any luck finding it. I just got a G&P metal body, and the pins were very tight going in, i dont think they will come out easily, unless i want them to. But ya, the locking pinsets are good! ascarmoury has them for 15 bucks, GOOD deal, recommend it!
