Im sorry but I will never go there again. I went there and tried that already, all they told me was to go to homedepo and get a screw that will work. They have no appreciation for snipers what so ever.
I mean hell as soon as I walked in there and asked from help the referred to me as the camper, people I have never meet before. Then when I cronoed my 2 guns( my tanaka and the Thompson I just got) they thought that my m40 was a KJW. Then when I corrected them they said I was lieing. Also when I cronoed I did it with .40s because my tanaka shoots way to hot with .20s, also I only use it when playing at my friends at his ranch, or at private games. they were like oh what are you using to get 500 fps .12s.
I dont know I have had to many problems there, hell I dont even get BBs from them. Hence the question, I was hoping to just get some on-line.
