I'm not sure why it took me so long to notice this but that color case work is absolutely gorgeous!!!!Are you oxygenating your water or adding nitrate?
I'm not sure if it meets your definition of tactical but FX is now making a .30 cal. bullpup called a Bobcat. It's apparently crazy accurate as it was just used to win the 75yd. extreme bench rest match hosted by air guns of Arizona.
So, who is making an accurate .30cal? Preferably one that has the tactical look.
