"Just perfect just don’t keep the spring down for too long or FPS will be lost
by Walker M. on 06/15/2024
"Solid 9mm ID springs. Compression settling is minimal (~5 fps loss after 2 weeks, might be 15 total after complete break-in). The FPS numbers, however, are NOT accurate with perfect airseal. Most spring companies advertise for people with stock rifles with crap airseal. With full airseal (compression test perfect at _1 minute at nozzle and barrel) the numbers I got are as follows:

M130: 500 fps
M140: 540 fps
M150: 580 fps
M160: 620 fps
by Alec M. on 12/22/2023
"Heads up, these are 9mm ID springs and do not fit traditional APS2 spring rifles that require 9mm OD springs. They are SSG24 only.
