First let me say I've had several different Ruger products and they have always been top shelf on quality. I just purchased a new American Rifle in a 223 rem caliber. It has one very annoying problem. I'm not crazy about the plastic mag but I realize it's all about controlling the bottom line. However, it should still work. It's difficult to load but that will just take some getting used to. The problem is when the bolt slides forward to strip off the last cartridge in the mag, as soon as the cartridge starts moving forward the head of the cartridge drops down allowing the bolt to slide right over the top of the cartridge. The bullet has already tried to start heading up into the chamber so the bolt just jambs it and pinches it trying to crush the cartridge. I'm really surprised this one got by Ruger. I reload and can shoot this gun for less than my larger calibers so I planned on doing more target shooting than anything, If I had known it would do this I would not have bought the gun. I could get by, by simply not cycling that last cartridge but do not like compensating for design flaws, especially in firearms. wondering if any one has had this experience and what did they do.
