Bearing spring guide + bearing cylinder head = repetitive?
I have a JG HK416 and it has a Modify bearing cylinder head installed. I'm wondering if it's really worth it to also install a bearing spring guide. It has the stock JG spring guide which is a solid chunk of metal so I'm not worried about that breaking anytime soon. It's got a Madbull M120 spring (pretty much equivalent to the stock spring).
