I've gotten a Wylde 5R barrel and then a muzzle device from them several weeks ago, but I haven't shot it yet due to lack of time and getting one last AR part ordered just lately.
They shipped in a couple days on the barrel, packaged well, and I was really happy with the price, fit, finish, etc., but we'll see how it shoots. From all I've read, I should be pleased. The muzzle device took over a week (maybe 10-14 days?) to get, IIRC, but I wasn't really in a hurry either. And, I think they were/are in the middle of a move, or something.
I'd order again.
