Wow.... Bullets that turn into fishing hooks. Talk about ultimate sporting gear recycling.Got a .223 upper and a .300 upper that can swap over. Same mags, same BCG, use the same 0.3" suppressor. Can load subs or supers depending on what i'm after.
Nice to use quiet subsonics in close bush on deer. Just make sure the projectiles you're using for subs will go splat on impact at those slow speeds rather than pencil through... LeHigh make some nice ones, but there are few other cheaper options out there now.

Oh, and if you're going the subsonic route, make sure you get pistol length gas on your upper. Will save you lot of headaches with cycling.
