The best lite BOB I have found is the blackhawk cyclone. a great survival .22 is the S&W MP15-22. the fastest .22 to clean and breakdown and really accurate.
and 25 round mags are great and work with ar15 30 round pouches. the gun is really amazing but many people will bash it but first try it.

Any day I'm above the grass and I'm not a zombie is a good day! JYD#138
