    Good book for what? Shooting? look at Magpul Dynamics videos.
    Green eyes and Black rifles.

  4. Sorry, I meant a book for dissasembly and build up. To learn how an AR-15 works and what you car replace etc. Different models and some history.
  5. I have all three of Walt Kuleck's AR-15 books. They are very good reading and have a lot of history.

    I conducted an accuracy evaluation of the 16” Colt light-weight barrel found on the Colt AR-15 A2 Government Carbine (6520) from a distance of 100 yards with the results shown below. The Colt light-weight barrel has a barrel diameter of 0.625” at the gas block and approximately 0.57” forward of the gas block. The barrel profile has a slight taper underneath the handguards from the chamber to the gas block with an average diameter of approximately 0.64”. The stripped light-weight barrel weighs approximately 1 pound, 6 ounces.

    The light-weight barrel is chrome lined, has a NATO chamber and a 1:7” twist. This barrel employs a carbine gas system and has M4 feedramps. This is the barrel traditionally found on the Colt model 6520 and now the Colt model 6720. This accuracy evaluation was performed with a LaRue Tactical free-float handguard installed.

    Shooting was conducted from a concrete bench-rest using a Sinclair Windage Bench Rest in front and a Protektor bunny-ear bag under the stock. The ammunition used; match-grade hand-loads topped with Sierra 55 grain BlitzKings. Sighting was performed using a Leupold VAR-X III with a mirage shade. Magnification was set at 25X and the scope was adjusted to be parallax free at 100 yards. Wind conditions were monitored using a Wind probe.

    Six 10-shot groups were fired in a row in a slow and steady manner. Those groups had extreme spreads of:


    for an average extreme spread of 1.69”. Using RSI Shooting Lab, I over-layed all six groups on each other to form a 60-shot composite group. The composite group had a mean radius of 0.56”.
