Things I liked:

Fits my 20+ year old Beeman R7 perfectly.

Things I would have changed:

I should have changed the main spring at the same time.

Things I liked:

I recently replaced the mainspring and piston seal on my well used R7. The new components made a noticeable improvement - the old girl shoots like new again.

  • Andres from USA asked:

    Dear Sirs I have an air gun model HWS 70 but the little information I've got, was manufactured 30 years ago. The problem I have is that I do not get the piston seal since it has an outer diameter of 25 millimeters and the inner is 8 millimeters. I have consulted several shops but the parts that have not adapted to the piston of the gun. Please where I could get the same and if they are so kind to send me the plane of that model. Thank you Andres Rueda
