Kinda too long but wanted to discuss why I decided to get my own springs made. Plus differences between cheaper Chinese and more expensive springs etc. www.ak2m4.co.u...
Apparently my s20 price has a week somewhere because hey guarder sp120 is the equivalent of a m135 spring. Thats 1.8j. my sr25 should be sure you're around that ballpark. Maybe even hotter but it's Only shooting 1.65 joules. Is definitely a step up from the original m120 but ibeither have an airleak or the power makes more sense and i had a m110 spring.
I was trying to leave a comment on you chronograph video for some reason you have the comments turned off. I was thinking of buying one but you mention that there are a lot of fake ones going around. How do you know what is fake and ain’t? They all seem to be coming from China
