Hello, I have a Spyder TL-R. So far, I have a 14' Whisper Barrel, Extreme Rage Overdrive E-Hopper (soon to get VL Revolution), a BSA Laser Sight (For rec. play), and I'm getting an HPA Tank. Besides the things I just named, what else can I do to my gun, and please explain what each of the things you listed are. Thanks.
