Green Mountain Barrels for modern firearms?

[johnpb]

I know GM makes barrels for muzzleloaders and from what I've read they make good ones. Has anyone had any experience with one of teir barrels for a modern firearm as in an AR15? I checked their website and they have some very reasonable prices, actually cheap, on their AR barrels but I just wonder how accurate they are and how they hold up compared to other manufacters. I sure hope someone has had some kind of experience with them. Thanks.

Not an AR but I put one of their .458 barrels on a 1884 trapdoor action and it shoots sub 1" groups at 100 yards.

Like the other poster, I have used the 45 cal barrel from them built a 45-120-550 and it works very well
