M4 Makeover

Couple years old but new to me: How an M4 became an M4A1:

    Well the M4 is a ‘makeover’ of the Colt Commando.

    So makeover of a makeover.

    You guys do know we have been essentially using the same rifle for about 50 years right? Same cartridge to.

    From what I understand, they need to get rid of that 1:7 twist barrel. The bullets fired from the 14.5 inch (or even 16 inch) barrel are going too slowly to fragment, and they are too stable with the 1:7 twist to yaw and tumble–the worst of both worlds…so you get nice .22 caliber holes that go through and through.

    They should either go back to the 20 inch barrel, or go to a slower twist rate.

    In the early days of the M-16 deployment, the reports from the field were that it caused catastrophic wounds to the enemy…now it seems that soldiers complain that it takes multiple hits to stop a threat. That early model of the M-16 was a 20 inch barrel with a 1:12 twist, IIRC. So, in close, the bullet fragmented and tore shit up…further out where velocity had dropped, it tumbled…and tore shit up.

    Turns out that it was a training problem in Vietnam that caused full auto to be (sometimes) misused. Fast forward and we find out that, with correct training, laying down suppressing fire can be quiet useful. My DoD, how lovely of it to risk us all to find this out.

Remember, I do this to entertain me, not you.
