With an EPM1 Spring Replacement Parts Kit you can replace a spring that is broken or lost its strength.
the problem often occurs due to forgetting to take BBs out of the magazine.
the other problem is that the spring ages through the skirm times and loses its strength slowly.
The spring is easy to replace, so you don't have to buy a new magazine right away.
THE EPM1 Spring Replacement Parts Kit is only suitable for the EPM1 magazines from PTS Syndicate.
