Oh Man. Now you've done it. First it's an AK, then it's an M4. Next thing you know you're into a matching set of Barrett .50 cals.
Man, I love this country.
Congrats on purchasing the cause of all the worlds problems, the evil assault rifle1
They are a lot better built than people give them credit for and a lot of fun to shoot. I have one as well and love taking it to the range along with my ar 15 and my dragunov. One of the ranges I go to has a rapid fire pit. The first range I ever saw with one. It is a deep hole and you can throw bottles of water or stuffed animals or whatever in it and blast away! Talk about fun. You never know what someone will have there. I've even seen full autos, uzis, mgs you name it.
As far as the 50 cal goes, buy one while you can, here in Illinois they are going to try to ban them.
