Save and purchase the 10 pack. The average length of the extended spring is .470. (The standard spring is .350) This spring is longer than the standard Sako spring. So if you drill the spring-pin hole to deep for the standard spring, this takes care of the problem. You trim to fit the depth of the hole.
