JT Distributing Kits? Any good?

[Radetwiggs]

wanting to get a 6.5 grendel...but for my first adventure into the world of the 6.5 I don't want to go all out and break the bank. I'm thinking about getting the 20 inch heavy barrel profile(not the bull barrel)....Are there kits worth buying? Who makes their barrels? what type of accuracy should i expect? any help will be appreciated.....
