Universal Air Rifle Spring Compressor 91XL-21, the tool for replacing air rifle springs.
With the Universal Spring Compressor 91XL-21, air rifle springs can be replaced in a safe and less strenuous way, and damage to the air rifle is prevented.
An important feature of the SC91XL-21, no damage to the air rifle, parts of the SC91XL-21 that come into contact with the air rifle are made of a strong technical pastic (POM/Delrin).
SPRING COMPRESSOR SC91XL-21 WITH WEIHRAUCH HW77 ACTION
FEATURES OF THE UNIVERSAL SPRING COMPRESSOR 91XL-21:
Replacing springs is safer, the rifle is well locked in the Spring Compressor and with the screw spindle the spring and cilinder end plug can be well managed.
No damage to the air rifle, parts of the SC91XL-21 that come into contact with the air rifle are made of a strong technical plastic (POM/Delrin).
Faster adjusment of the screw spindle by the use of trapezoid thread spindle.
Ample adjustment options to adapt the Spring Compressor to the air rifle.
Comes with 3 different stop discs. A 16½ mm slotted disc, a 21mm slotted disc to accomodate different barrel diameters and a non-sloted stop disc for customization (if needed) or for need with a air pistol.
The Spring Compressor is designed to be used for air rifles, but it is also possible to use it for air pistols.
It must then be taken into account that the minimum distance in the Spring Compressor is 225mm. So if the lengh of an air pistol barrel/cylinder assembly (without pistol grip) is longer than 225mm, then the Spring Compressor can also be used for that air pistol (in the case of air pistols, the supplied stop disc without slot (pos. 6C of the assembly drawning) must be used).
The Spring Compressor is not suitable for the air rifle models BSA Airsporter, BSA Mecury and similar constructed air rifles (some types of german Falke air rifles) due to the shape of the trigger housing and construction/compososition of trigger housing with cylinder.
The Spring Compressor is suitable for both right- and left-handed persons. If desired, by turning the 2 clamping plates (pos.10 of the assembly drwawing) this can be easely adjusted.
Solid and nice construction, sturdy powder coated (black) aluminium frame, stainless steel guide rods, brass trapezoid nut.
Made in Holland, comes with a Dutch and English manual.
5 years warranty after purchase.

I got the compressor yesterday! What a fantastic device! I love it!
I swapped the spring on my HW97 that has a lot of pre tension with real ease. No problem at all.
Best wishes and merry Christmas!

I received my press today. I am very pleased with my purchase. The quality of the materials, design and function is superb. I have had a HW80 sitting at home in pieces as I couldn’t get the spring compressed enough to assemble it. With your compressor it took me 5 minutes.
Thanks again, great service.

It is extremely well engineered with a superior design which stands head and shoulders above the rest, which are based largely on a sash cramp. With your version there is no doubting it inherent safety. Two very ingenious cylinder clamps makes it a perfect design constructed of the very best materials.
I am very pleased with it and would like to take this opportunity in thanking you for your speedy service in delivering the very best of the best.
My best wishes,

I have dissembled and rebuilt my HW77. Your spring compressor works absolutely perfect!
It is super easy to change the spring. The spindle allows very fine movements and so it is no problem to unscrew the end plug without damaging the thread. With a little mark for the beginning of the thread, reassembling is also very easy.
My concerns about the friction between the Delrin block and the end plug were absolutely unnecessary. The surface of the Delrin block is so hard and smooth that there is almost no friction.
Your compressor is perfect as it is and changing a spring was never as easy as this time!
Really a great product and I am completely convinced of the functionality and quality!
Thanks and best regards,
