While your rifle is maybe not as nice as 783s, the general impression I have is rather positive for a budget rifle. Machining marks? Well, Ruger is using the forged steel receiver, bolt and cold hammer forged barrel. You can't say the same about the other, budget rifles. If finish is your prime concern - than yes, by all means it may be lacking. I however, basing on my own gun counter experience, believe that 90% of the people shopping for a cheap rifle are not concern with that. They want something that work and will last a bit while providing the user with decent accuracy, so they can harvest a deer or two every season. For this role, Ruger American offers a lot of value for the money, even when compared with similar rifles on the market.
