been having a similar issue with Modify springs. tested on 4 different guns and got the same numbers..
M110 is getting 330-340 FPS, and the M120 360-370. i would like to be in the 390 range.. but i dont want to be using a M130 to do it. on their site it stats that i should be getting 360 to 390 on the M110 (110 x 3.28 = 360FPS), and that the M120 should be getting 370 to 420 FPS (120 x 3.28 = 393FPS).. now are my numbers screwed or is Modify over stating theirs?
