So, I've ordered one AR 15 lower and I will order one more tomorrow in order to let my home state for a few more months know that I am a law abiding gun owner who bought ARs just because they didn't want me to have them. I plan to build a 450 Bushmaster rifle on one as I will use it to hunt pigs on a friend's ranch in Sonora TX. No one whom I know has an AR in that caliber over here in Ill-Annoy or in Wisconsin and I would greatly appreciate any advice / suggestions / information that anyone might have for me.

Thank you very much for the help in advance and good hunting!
