I've been looking/reading for months now on POF, LWRC, and LMT piston ARs and had just about settled on the LMT, but for some reason never gave much thought to the SIGs until recently. From everything I've read, the 556 sounds like a great rifle. Anyone here own/shot/have experience with one?
As for .40 S&W, if anyone needs trash range ammo, the Wal-Marts in Pensacola were selling Blazer Brass reloadable fmj boxes of 50 for $7.57 last I checked. If anyone's near Hurlburt or Eglin and you're headed that way, it's not a bad deal. It's been a few months so I would call first, but my 229 will eat it all day long and I've never had trouble with it while plinking.
