Hey guys. I'm a definite beginner when it comes to airsoft guns, what all the terms mean, upgrades, and all that. So I have a few questions. To start this https://www.evike.com/products/28201/ is the gun I run, tts the tan para version. I absolutely love airsoft and want to better upgrade my gun but I have no clue where to start and what attachments/internal upgrades are available for this. As I said I have zero knowledge lol. So anyway: What would be useful interal upgrades? What is the best battery/what is lipo? I keep seeing links to hobby king about lipos and entering all this battery information but dont know where to start! How do I upgrade RoF? How do I upgrade range? Is there any way I can add more rails or something to the 249? It seems like all the kits are for mk46's Thank you to anyone who takes the time to respond to this or anyone who can help me. I really haven't got a clue where to start!
