"So... This is a good spring. That said... Story: I have a DMR build and originally had put a m140 spring in at the time i built the gun. Did some test shooting after it was all put together and it seemed as though the gun was shooting over 450 (D14 DMR Field Limit) just by observation. So i order this spring as a downgrade. Slapped it in there and said there. That should be good, without testing it. Went to an event the upcoming weekend and walked up to the chrono. First shot 500 FPS exactly. Second shot 497. Third shot 500. Puzzled i told the chrono man it had a m130 spring in it. He was puzzled as well so he put a different fresh mag in. pew 500. Shot again. 490. So in disbelief i stripped my gun down on the bed of a truck, opened the gearbox and slapped a m120 in. Chrono 350 FPS steadily +/- 4 FPS. Took my gun apart again and put my m140 spring in and chronoed. 410-420 FPS Steady. I have no idea why this spring is shooting so hot in my gun but definitely does the pew pew more than advertised. I understand it was a new spring so it would be shooting hot before it settled but thats a little extreme for a m130.
