So I want to order a few parts for my TM guns, what's the best way to go about it? I can see that each part is numbered, and there seems to be an order form in the back of the manual. But I remember someone saying you could go into some stores and get it done there. If anyone's done this before or has any info I'd appreciate it.

Take your manual into any shop and point out the items you want and they will order them in for you. That seems to have been the easiest for me, although some parts have taken a LONG time to arrive (almost 6 weeks for a SOPMOD hop-up unit )
