Terra,

I had my XCR switched over to the new gas adjustment valve, recently.

I sent my barrel in, but not my operating rod. Great job quickly done and returned.

When I switched the new piston on the end of the OP rod for the old, I apparently left out one of the weights. They all had fallen out, and one found a place to hide. (tradition, don't you know)

I have shot the rifle since, with little problem. Is it critical to add that weight into the op rod?

Please advise.

Additional question, RE: the weights in the op rod. What is the purpose of the weights? If they are not critical, is getting rid of the weights, a method to lower the weight of the weapon? What would be the result of said action?

Thank you

Fred

Fred,
We have actually test fired the gun without any weights at all in the op-rod, and it still functioned okay. If you are doing a lot of rapid-firing, you may experience some "bumping", due to the lost weight. Basically, you will experience some misfires and bolt bouncing. That's about all that will happen. The missing weight is really not a big deal. If it would make you feel better, I can send you a weight to replace the one you lost. But, like I said, it really won't affect your rifle's performance.

Terra,

Thank you for the offer and the fast turn around on the information.

It was one weight, I didn't know I had lost it until I found it.

I don't need one. And so far the rifle is firing just fine.

Thank you again.

Fred

Ok

My XCR is about 6 months old ....what weights are you talking about ?

Unscrew the piston on your op rod. There are 7 brass weights inside it. if yours doesn't, then it's not one I assembled.. haha.
