Swiss K-31 Firing Pin Spring

$12.95

It’s hard to believe that anyone could improve on something the Swiss built but we did!  Introducing the RSI custom wound Swiss K-31 Firing Pin Spring.  This spring was developed in a joint venture between the owner of WWW.SOCAMO.COM and C&R Spring Company LLC, the same guys who designed our incredibly popular Mosin Nagant spring.  Their goal was to create a spring that would improve the functionality of  the Swiss K-31 rifle without sacrificing reliability.  Each spring is made using high quality steel,  the spring ends are then squared and ground.  Then they are treated with a black oxide coating to prevent corrosion.  Once the spring takes a “set” in the bolt the user will see a noticeable improvement in the performance of their rifle.  The new design significantly decreases lock time and to improves bolt cycling (one of the biggest complaints about the K-31).  This new spring also makes it easier to disassemble the K-31 bolt for cleaning.
