I have been running a Quicksilver can for a while now (gave up my G5). The last time I cleaned the rifle I noticed that the rear buffer was mauled to pieces. I addressed this with Alex and came to the conclusion that the excessive pressure (more than usual) from the Quicksilver was the issue. I got Alex and Dr Quilligan together so information could transpire. I suggested to Alex that we change the suppressor gas hole to a smaller dia. I have reduced the current .046 gas hole to .035. so far no problems.............

Just for clarification, were you using the old gas system, or the new one? (The old one had a suppressor setting as well, right?)

Actually, under the old system you could order a different gas port that had a supressor setting on it but the system from the factory didn't include a supressor setting.

Andy, are you running the new gas system?

I am not sure if it is the old or new system. We were one of the first companies to receive the 12 in short XCR. I had the old firing pin so maybe we had the old gas system as well. Our gas dial had notches not numbers and it did have a suppressor setting. As a clarification the factory suppressor hole is .043 not .046 as I stated below. We filled in the .043 suppressor hole and drilled a smaller size.

This is a pic of the new gas system, the adjuster is rounder than the older model and it has a detent you press to adjust the gas setting (not taking a wrench like the old system).

If that is the case, I have always had the new gas system. I just had the notches on the valve instead of the numbers.
BTW, what type of brake are you using?

That is the brake that Robarms provides on the 6.8SPC. I have since shortened the barrel to 11.5" and put on a PWS brake.
