Let me start out by saying that I work as a purchasing agent and therefore deal with sales and customer service individuals every day. If 1/10th of them were as friendly or as professional as Tuna it would make my life a hell of a lot easier. Tuna walked me through every step as far as building my marker, different options/configuerations, and any sort of questions that could arise. There was not one time in which he tried to push the upgrated, more expensive part on me. I can't tell you how refreshing that is after walking into my local shop and always having the salesmen trying to shove a 1500 dollar marker and 500 dollars worth of excessories down my throat and all I came in for was a case of paint. One week after recieving payment I had a custome built mag delivered to my door, for a fantastic price. All I had to do was add paint and air. If you are looking to purchase a mag or mag parts look no further as you have found the place. The only issue I have is that Tuna will be getting a substantial percentage of my salery from now on. to Tuna
