I just re-zeroed my 6920 on sunday after mounting a new Aimpoint M4s. I zeroed it at 50, checked it at 100 and 200, ammo was Win. Q3131A. I was slightly impressed with the 50yd group, not very impressed with my 100yd group but was astounded with my 200yd group. At 200yd it put 14 out of 15 rounds inside a six inch target circle. To echo 'Gunz, how much accuracy in enough. If working up a precision rifle I would probably lean toward a SS barrel, but on a working carbine I would venture to say that a chrome lined barrel is more than accurate enough. More accurate than most of us I would say. On a working gun I will take the reliability and durability of a chrome lined barrel every time.
