I have a "stock," as far as I know, cobra mamba IR3. It does have the jewel. Worked great last time I shot it which was admittedly quite a while ago, so it might need some lube or cleaning. Board works great and battery hold a charge fine. Comes as pictured minus the breech knob, it has a pink one now. I am asking 300 shipped and paypal'd and I am pretty firm on that price. The gun is in great shape and I wouldn't mind keeping it but a little extra spending money in Vegas wouldn't be bad either.
