Replacement spring
Hey guys. I have a CA m15a4 with stock internals and 25,000 –ish rounds put through it.
1. My fps has gone down. Nothing dramatic, it just doesn’t have as much “omf!” as it used to.
2. This is a result probably of my spring wearing down, correct?
3. Should I replace it with an m100 (basically my stock spring), an m110 or an m120? My head tells me to go with an m110 as an m120 would take other upgrades to make the gun stable, correct?
Thank you for your patience.
