I have a 12 Green Mountain Monster Logo barrel as sold by SixFive Outfitters and I really like it. Precision Firearms and Craddock Precision have very good reputation for turning out accurate barrels. Precision Firearms offers a discount to new 6.5 Grendel forum members. Lilja barrels have gotten good reviews on this forum and rebby with six sigma arms has done a couple group buys on Lilja 6.5 Grendel barrels.
