Springfields receivers are fine. The issues show up with cheap Chinese knockoffs that guys buy, who want an M1A or M14 and don't want to spend the money to get one. There was some talk a few years back about Springfields not being the same as what they used to be but I've never seen the difference and never found anyone who has either. I have two, one stock rifle, one completely custom, they are great guns. If you are still curious search out the guys who build service rifles for Camp Perry type shooting and email them, see what they say.
