Страйкбольные поршни , и почему я не люблю алюминиевые

Link to the VK group - https://vk.com/strike_epik_tun   / strike_epik_tun   - My Patreon Channel, with unique videos and technologies. Well, they asked why I don't like aluminum pistons, I decided to tell a little about others, I once told, but I had to erase the video, all the pistons I told about hold a 150 spring, aluminum ones of course more, but why is it necessary? Mostly CXC pistons, 1 guard, 2 spare parts,
