AR help

[oldyeller]

I am brand new to AR15s, and have a 6x45 barrel coming that I want to mount on a M4 flat top receiver. I have the nut and delta ring set, is there anyone near Santa Rosa that has a barrel wrench that could help me torque this on with? Also, maybe one of the guys going to the SR build party could help me.

Thanks!

You need more than just a wrench. You'll also need an action block for the receiver.

Did you mean 5.56x45 or are you building a wildcat 6x45?

Brownells has a good tutorial on what you'll need to do.

I'd go with a DPMS block.
