LaRue Pistol "build"

[McD18]

Could be cool. But I would want a custom barrel to replace it with instead of BA.

My thinking is if your going to go to all the trouble too buy it and then tear it apart to pull the barrel. Just assume go with a top end custom to replace it with.

I was thinking I'd order it until un-assembled and just toss in the BA barrel. Doesn't seem like much trouble at all.

Sorry I'm an amateur with building ARs, what's the advantage of a custom barrel? I was under the impression that BA made good stuff and perhaps commensurate with LaRue.

Thanks for your replies.
