Thread: Ruger 10/22 Mainspring dimensions

Hi folks - looking for some dimensions on ruger 10/22 mainsprings.

Outer diameter of the springs (A)
Inner diameter of the springs (B)
Uncompressed overall length of the spring (C)

If you're feeling charitable then also
Wire diameter (D)
Number of coils (E)




This spring:

Have you asked Darin at usaguns.nz if he has any springs in stock?

Would help but mines been altered( some coils snipped off )

Yes I know those diameters don't work out. Take your pick.
Also this came from a hack which has excessive round count and often left locked open.

Great, thank you for that!
Helping a friend out trying to fix a marlin rifle that has a bent mainspring. Hard to get springs for them, so looking to see if there are springs on the market that could be used instead.

Much appreciated guys!
