We don't ever expect you to need to replace your spring retainer but we have them if you need them. This production piece contains the base of the spring and snaps into and redundantly secures the basepad to the mag body. Being red, it is much easier to locate than a detent.  

 *MOD1 and MOD2 compatible*
