Stop in at Blue line this after noon. To pick up some mag's for my GSG 1911. Ask Scott if there was up grades for it. More then willing to pay for them, since I did not buy it from them. Scott put in a new guide rod, guide rod spring, and washers. He did not charge me for these part's. Just had to leave a thanks for the awesome service you guys at blue line are giving. I will defiantly be coming back soon. Hmmm I just might see a new AR in my future.
