AR57 Full auto Bolt

[rsx11m]

I have tried every place to find a bolt for my AR 57 5.78. I believe the bolt slip out of the back during my recent move and is floating around some place in my household goods. I would advise everyone that has this ar57 upper to at least put tape across the back of the bolt in order to keep it from sliding out when not attached to a lower. Getting desperate I have something I cannot use I'm willing to pay $750 for a full-bolt that meets the AR57 specifications. Have form 4and will supply a copy of necessary.
