Nope havenít done anything to the weapon, actually itís the first time i shot it, traded a m1a for it. So on the oprod where would the weights be located I pulled it apart last night, everything looks new, zero wear on any moving parts, bolt, carrier internals. I donít see anything resembling weights on the oprod, but again I havenít had an xcr in a few years so Iím not sure where to look. And no I havenít modified or touched anything on this weapon. But the rifle has been modified in a sense I guess the previous owner owned a lot of these weapons and was very knowledgeable, but he did modify it, as in he upgraded said weapon to all the current factory parts including the fast stock. Bonus point to this xcr is that even with the malfunctions itís still more reliable and accurate than my scar 17 I can get about 2 rounds out of it before it malfunctions lol

It would be inside the op rod behind the piston head. You should be able to tell beforehand if it's weighted by shaking the oprod up and down though. You would feel them moving around inside.
call Robinson and send it in.....you said it has been upgraded so the oprod piston should be over 5" long and no counter weights or weld in the body...Allen will probably have it fixed in a few minutes (He is very good)
Let me know what you come up with when you contact them
