Bolt Carrier Tilt Ruger SR-556

[charliedontsurf334]

I want an AR Carbine with a Quad Rail. I thought that the Ruger SR-556 was what I was looking for, but I've read a lot about bolt carrier tilt. The Stag Model 8 has rails on the bolt carrier to deal with this. Has Ruger done anything to fix this?

Carrier tilt is a byproduct of piston systems. If you get a standard DI AR, this won't be an issue.

What about Carrier Tilt on the Stag?

What made you think that a piston AR was what you were looking for?

What are your findings, based on all that you've read about bolt carrier tilt?

What is unique about the inside of the upper receiver of the Stag Model 8, where the pads or rails on the bolt carrier contact?
