Remington 700ML/Model 7 Main Spring – F15411 equivalent

These springs are made specially for us, in the USA, & from US materials.   These springs are subjected to a rigorous production and QA regime in the US:   They are wound, ends closed and ground, set, treated, and oil dipped by US craftsmen who do QA steps at each point of the production process.

​​​A must have when converting a Remington 700 ML/MLS to 209 primers as the original system subjected the mainspring to lots of heat, extra cycles, and corrosive blow-back.   Its a rare day that I work on a bolt running a leaky system that doesn’t have a worn out and corroded mainspring.

This is the spring that forces the  pin forward to strike the primer in the Remington 700 ML/MLS rifle; it is installed inside the bolt body, around the pin.

This spring also fits the Model 7 rifle.   We use these in our first generation 209 conversions for the Remington 700MLS (see picture below for more information).  These springs are made in the USA out of US sourced materials.

If you don’t want to install this spring your self, we can do it for you.   Click here to read more about our mainspring replacement service.
