So lately I've been getting really into airsoft and how airsoft works. I always try to stayed away from the tech because it intimidated me on how there are so much things going on. Today, I wanna face my fears. I really want to be dedicated into airsoft tech-ing but I don't know where to start! I'm tired of spending vast amounts of money going to an airsoft store and letting them fix my guns! I have a Krytac Trident SPR Mk2 and I want to Polarstar it. I heard it's fairly easy to install them by yourself but I don't know anything inside a gun and I don't wanna break my baby. My local store is charging me $75 just to install it in so I figured I might aswell do it by myself. I know there are tons of airsoft veterans who mastered airsoft tech in this site! Any tips about Airsoft tech for a beginner would be great!!
