I have a 550 American in 270. This is an excellent gun. Aside from the 0.8" groups I get at 100 yards, it's ergonomically very comfortable to shoot. It's easy to maintain. When I was shopping, I compared it to other brands and saw no reason to pay more. The wood in the stock is nice and straight-grained and it's very practical. It's not the most gorgeous wood in the world, but it's functionally good and is real walnut. It comes with the rings. The rings are a bit high, but they work, fine for me. I'd buy another one. The trigger had a bit of creep when I got the gun, but the manual gives clear instructions for adjusting it. It's very easy to do, but the stock has to come off. The result is the best trigger I've ever felt on any rifle. The set trigger is a neat feature. I've never actually fired a round using the set trigger. I might if I ever want to shoot 'chucks or 'dogs from a bench.
We also have two of the .22s-- the youth model and the Lux. I bought these first and I thought they were excellent so I bought the .270 when I went to shop for a centerfire.
No regrets here.
