6.5 Grendel is a low pressure round and is not a barrel burner. At 200-500 rounds a year a stainless steel 6.5 Grendel barrel will last 10-15 years. Precision Firearms, Lilja and JP get good reviews. Wilson Combat barrels get good reviews as does LaRue Tactical who offers a Nitride barrel. The LaRue Ultimate upper is a good value for a complete upper. Odin Works stainless steel barrels get good reviews for mass produced barrels.
