Let's face it. Who needs an ACOG or another top of the line optic? Who needs a SOPMOD? Who needs 4150 steel, a Pentagon / Surefire?
If you really think about it, probably only about 5% of the real operators who use it everyday to defend their lives with.
However, I want the best products that I can afford because I want the best and want to train on the best. Not only do I have nice toys / tools to play with, I'm ready to go if I ever needed to put it to use.
It's like saying why buy a Corvette when the speed limit is 55. Why not just buy a KIA? It will both get you there.
There are people who buy clones and have a great time with it. More power to them. One camp shouldn't bash one over the other. It's your money, your toy / equipment. Do as you please and don't give 2 squirts to what others think.
