  • Coiled mainspring
  • Fits Beeman S1 air rifle
  • For professional installation only.

Mainsprings can break or lose their ability to flex back to their full, original length, resulting in reduced velocity. If that's what happened to your Beeman S1 air rifle, this is the correct replacement spring to bring it back to full power.

Things I liked:

Worked great to rebuild a Beeman S1, The old spring was worn out and it would hardly shoot through a tin can, Now it can shoot through a 1" phone book.

Things I would have changed:

Nothing to change

What others should know:

Great for restoring the performance on older air guns

  • Enrique from USA asked:

    would that spring fit beeman Rs2 air rifle too?

    • Steven from USA asked:

      I've read on another website that Marksman 45 and Beeman S1 use same spring.Shawn Kyzar, did you purchase, does it work? Dan the Man, did you try and have it not work for you? If so was it just too long?

      • Shawn Kyzar from USA asked:

        This should be a direct replacement for a marksman model 45 right? Was a beeman s-1 sold under the marksman name. Can anybody tell me for sure?

        • Dan the Man from USA answered:

          No, it will not work.

        • Jerry from USA answered:

          From what i read yes, it should fit.
