Sold my HK91 the other day and decided to get another "Fun Gun" that didnt cost so much to shoot. I went to sportsmans warehouse to pick up a GSG-5 and saw a tag that said SIG 522! I hadnt seen nor heard of it but I picked it up and fell in love at first touch. Sure, it cost $500 but the mags are easy to find online and it was an all aluminum upper. The S&W and Ruger both seemed a lil excessive. If I am going to spend that much on an AR lookalike, Id just as soon buy an AR for a couple hundred more. I noticed it didnt have any iron sights but I can do with a red dot for now. I will invest in irons at some point. This thing has also got me looking hard into a sig 556. First day at the range, it was -10. I lubed it up, loaded the mag and blew through 200 rounds with not a single malfunction. I had a BSA red dot lieing around so I threw it on, it sighted in in 5 shots, and I was getting 1.5" groups offhand at 50 yards and the same on bench at 100. I was shooting all CCI mini mag ammo. I tried to fold the stock and it was a Pain in the butt. I finally got it to snap into the forgrip tab but it took some doing. I'm sure it will get smoother as the time goes. I ordered 4 more mags and a rail set from sig to go on it as well. Should be a lot of fun when it gets warmer. I would like to see whats up with the lil storage tube where the 556's gas tube is located.
