It is not a brand that I have used. There are some low cost guns that I have with reasonably good results, like Armalite, Stag and ADM. Not sure if they do a Grendel.
If I were you, I would JUMP over to LaRue, and buy the Stealth kit. I got a 6.5 Grendel for $800. Everything except a lower. Lower parts are included. Buy a nice billet lower of your liking for $200, and you have an amazing rifle for $1k.
