Spoke with gentlemen handling tech support and he says that's the way they come and there's nothing that can be done. He says rifle should cycle without issues and insists there are countless satisfied customers with this product. He was very nice about it but said I could send it straight back or try it and see if it'll work. I haven't tried it yet as I'm in a commy state and it's not the easiest to get to range without fighting hoards of 2A Patriots exercising their 2nd Amendment, which means I may have to sit in my car for 3hrs like last time I went to the range... good news is the gentleman I spoke with said if it doesn't work well I can return it for a full refund up to 1 year. We'll see what happens. Irony here is this thing is made in China and is replacing a part originally made in China, ya think they could get it right? I'm guessing they don't really care as I'm 100% certain they know full well their finished product is off. Let's see what happens. Good luck. I hear some people get lucky and actually get one that fits well.
