I have one of the more recent .308 American Predators that come with the four round, flush fit, more conventional staggered magazine.
My magazine has issues with not pushing the second and third round to the feed lips, requiring me to smack the side of the rifle, or take the magazine out and squeeze it. The first and last round feed fine. I finally got annoyed enough recently to email Ruger about it and they are sending me a replacement magazine, hassle-free, with instructions to send the rifle in if the new magazine doesn't fix the issue. It's certainly the magazine, though, as I can replicate the issue with the magazine detached from the rifle.
While the comb could be a bit higher, I otherwise have no complaints about the rifle.
Forgot to mention, accuracy is phenomenal. I anticipated purchasing a box of several different factory loads when I first got the rifle. The first time taking the rifle to the range I grouped some 150 grain Winchester Power-Points that I'd already had on hand at about a half inch. I simply went out and bought a couple more boxes of Power-Points. I saw no reason to try anything else. How was I going to be able to beat a half inch with factory ammo?
I'm now nearly set up to hand load, so I'm excited to see how well I can get some Barnes TTSX bullets to group.
