    This Kit is great, and went together well. The machine work & finish is excellent. This kit builds are really slick looking AR, that is also practical for accessories.
    At sight in the gun shot a very tight group with iron sights (MBUS) @ 50 yards, using a pet handload that I run in my other 223s. (55 grain FMJ) The 1 in 8″ twist rate stabilizes and handles that load with ease.
    I really hope Anderson makes more kits in other set ups (Like a Varmint Bull barrel kit!) so that I can add more to my collection.

    Good job Anderson!
