I would define a tactical shooter as one who trains for combat situations. A hunter who uses a muzzle loader and trains to shoot that isn't training for combat. Make sense?
Nothing in your article talks about how each has performed in combat. Seems like your basing your opinions on range time, accessories, and the internet. That's ok, but if this is about "tactical" or combat arms, I want to know how each worked for you in that arena.
You can edit your original post and hit the enter key to put in some paragraphs. More people would read it fully.
Oh, and my experience with tapco has been that everything from them is crap, except the G2 trigger groups, and the muzzle break.
