I just got my rifle back from Gunsmiths Inc (Tim Ward) who upgarded my Les Baer AT-15 Police Special. I had Tim replace the barrel with a Krieger barrel with 1-7.7 twist. He cut it off to 20 inches, crowned it, and chamber it. Replaced the handguard with a LaRue Tactical 13.2 and a Magpul PRS stock. The scope is a NightForce 2.5-10 X 32 with Zerostop and Nightforce unimount. The rifle performed well today as I was breaking it in and making scope adjustment. The Krieger barrel is great with little to no copper fouling. I think the groups will improve with more rounds and practice. I like this gun.
