[topper]

i have a spyder TL-R that is basically a speed ball gun cause it shoots crazy fast and has a ton of mods almost everything i can get. i have the rocking e trigger frame on it the derlin bolt and high tension spring e hopper but there is a problem every time i put it on full auto and let it rip the cocking pin which is postioned vertically on my gun flys out im not sure why yet but i was wondering if you guys could help me out. i think it might be the spring since its day and night from the stock spyder spring but so is every mod i put on it
