If the price is going to change, military should get a discount. Have some eff'ing respect!!

None of the shops on Oahu would raise the price because someone is military or because they're a Haole. Lets just dispel that stupid crap here and now.
Prices for rifles sold at the in stores are based on total cost to dealer plus their % markup. The problem is the distributors have raised their prices and in some cases the manufacturers have as well.
Now is a rough time in firearms. With gun bans looming, you might not be able to buy an AR type rifle in a couple of months. I guarantee you that you wouldn't be grumbling about the price at that point.
Many many years ago my Grandfather and Grandmother bought a house in the "Diamond Head" area. They were told how stupid they were for paying so much. They were ridiculed by their friends and family because they paid more than anyone else had ever heard of for a house. They didn't care though what others thought. Even though they paid a premium price for their purchase, they were happy because it was exactly what they wanted. Years later, the purchase appreciated in value and they weren't looked at as "fools" anymore.
The price they paid for their home? 3000 dollars.
The moral of the story is, if you want something and can afford it, buy it.
