When you tighten the barrel nut to spec it won't. There is no need to "bed" the barrel in the receiver. The nut centers and clamps the barrel flange.

Would you say that a certain amount of "slop" between the two is acceptable?
In other words...my other builds have been nice and snug...this one is slighly looser than my others. It's enough to hear it nocking back and forth when I rotate it. Of course, this is all without a barrel nut installed. |

As long as it doesn't do it once the nut is torqued, your rifle will be just fine. |

I don't anticipate this problem...just want to learn about my options. |

the "slop" may induce excess windage if you have a barrel with FSB. You can cut a small strip of Aluminum from soda can and shim it before tighten the barrel nut.

I don't think there is enough room to shim anything...the clearance is very, very small. I would not know how to begin getting anything to sit in there.

if you use a receiver action block to tighten the barrekl nut it will twist the barrel to the left POSSIBLY creating a "canted " front sight ( it's not, it's the whole barrel over a few thousanths)
if this is the case and you have to use a lot of windage (here i'm ASSuming irons) to sight it in, you can take it back apart and use a barrel clamp(have someone hold the upper) and tighten the nut. this will allow the nut to tighten without "twisting " it in the upper. either way it will function fine. if your running optics it doesn't matter. i know of people who purposely make the slot in the upper wider to rotate the barrel. i am definitely not a expert |

Why would anybody do this on purpose? This is exactly the source of the rocking back and forth I am seeing... i am definitely not a expert |

The index slot in the upper should be .125", how wide is yours?
With the barrel nut torqued the barrel well not rotate. If you are using a FSB attached to the barrel it well effect windage. |

The coke can trick works very well.
And for those that think ' shim ... no way in my rifle', just think about all the shims in any high performance engine. |
