We examined the Remington original action springs (F401305) and found them lacking.   So we improved them.   We call our spring the “F401305IMP”.   “IMP”  stands for improved.  We improved the original by carefully examining its designed spring rate, and then changing the dimensions and components in-order to preserve the original spring rate , but keep it at that rate for a longer period.  This spring pushes just as hard (no harder, or no less) than the original, but it is made with more metal:  It will out last the OEM original and preserve the VersaMax’s wonderful reputation of cycling light and heavy loads reliably.

Remember to keep this spring clean and lubed with appropriate gun oils/high quality lubes that do not gel when cold (for hunting guns).  Competition guns sometimes can get away with thicker lubes if they won’t be fired in cold conditions.  Unfortunately the need to clean and lube the recoil/action spring was omitted from the Versa Max’s owners manual.

​Sometimes installing our “Remelli kit” and cleaning the action spring fixes light strikes, if it doesn’t (or you are smart and just want to fix it all while you are in there), replacing the action spring is the next item to check off.

You may find other vendors claiming their springs are heavier/harder and therefore better.    Some of their claims smell of “magic fairy dust” and “snake oil”.  From the factory the VersaMax shotgun functions well with all loads, hot or soft, with the original spring rate: Changing rates (ie putting a spring in that pushes harder), or making unrealistic claims just doesn’t make sense.  The gun won’t work as well with lighter loads if you put in a spring that pushes harder.  Remember the issue isn’t how hard the original spring pushed: the issue is that it wore out prematurely!

We cannot replace the action spring for you.  Use the owner’s manual’s procedures to unload, make safe, remove the barrel, bolt assembly, and trigger assembly, then remove the butt-pad,  then remove the buttstock with a 3/16 hex drive in order to access the recoil spring tube.   The recoil spring & plunger are retained in the tube by a 19MM (3/4″) retaining nut.  Be careful! The 19mm nut is under spring tension!  Remove clean, and replace as desired.
