Gunsmithing Need A FN SPR Extra Power Striker Spring

[kl3309]

Have a 2006 production FN SPR in .308 and am looking for a replacement striker spring. Anybody know of any extra power ones out there?

Brownells has a section on replacement springs.

Looked there first. They've got a Wolff spring listed for long and short action, Pre- and Post-64, but the SPR is that weird WSSM action I think. I'll email Wolff to verify.
Thanks though!

My SPR has the same firing pin spring as my win70 short actions

Thanks!

I actually just order 2 for short action 70s the night before last. Brownells said 6-8 weeks for the special order so I went straight to Wolff.

These are the specs Wolff emailed me for their 25 lb. spring:

Wire size - .054”
End OD - .410”
Body OD - .403”
Body ID - .295”
Length – 5.61 inches long with 37 coils

How does that jive with the factory spring?

Old spring on the bottom and new 25lb Wolff on the top

Thanks for posting that!
