Any info on the diameter, material/finish, solid length, or stiffness?

The spring is designed as a +3 for 7+1 for the Remington 870Reaper wrote:How long is your spring for a 2 round mag tube extension?
we do the math and testing on them when we need to trim them for length for other mag tubes.

Material is HTSR chrome silicone and is 41thou thick, the rest of the info is proprietary information, and that info is what makes our spring better then most.Synchronizor wrote:Any info on the diameter, material/finish, solid length, or stiffness?

Re: High quality shotgun mag springs
A Cr-Si alloy is a great choice for making long-lasting springs that will be subjected to shock loading. High relative elastic limits for both compression and torsion, and low sensitivity to temperature. Points given there.
But really? The spring's diameter and solid length are proprietary information? How are folks supposed to know if the spring will be compatible with their other magazine components?

I have your S & J 750 mm magazine spring. How long does it need to be for a
+2 extension, 6+1. Millimeters is OK, I can convert to inches.
conversion factor: 1 mm=.0393 inches

spring's diameter and solid length are proprietary information, no not really but we have so many people trying to rip off our ideas and copy our format, we just don't want to put any more info out there that's not needed.Synchronizor wrote:A Cr-Si alloy is a great choice for making long-lasting springs that will be subjected to shock loading.
