*OR if they loose more than .5lb of pressure, (your spring that used to be 8lb is now 7.5lb), whichever comes first!

 

We recommend testing every new spring prior to installation to record exact spring weight/pressure. Spring weights will vary to a degree and it’s always good to have extras on hand.

 

It is critical with every recoil change to check the new spring to ensure there is not coil bind. See video below for more information:
