XP40 High Performance Perazzi Ejector Springs


Developed and manufactured exclusively for Sportarm – XP40 replacement Ejector Springs

Having calculated the internal and external maximum spring recesses and coil diameter Sportarm set about developing a set of Ejector springs that deliver 40% more ejector power resulting in better cartridge clearance from the barrel, suitable for 12g 20g 16g  

The kits comprise of two XP40 ejector springs, Perazzi grease and ejector removal block to aid fitment. Please note fitting and removal is done under tension and if not confident should be carried out by a trained gunsmith.

1. Use block supplied to compress the extractor, making sure the block doesn’t interfere with the barrel locking ledge as shown in image. 
2. Once fully compressed, use a toothpick to remove the cylindrical ejector retaining disk (shown in image with hole in centre). This disc is about 3mm deep and has a bevelled edge on the top surface. Please note, care must be taken to ensure the domed side of the disc is facing out during reassembly. The disc will require a little 'jiggle' to remove.
3. See image, disc being removed. Please note, constant pressure to the ejector spring must be applied during this process.
4. Once extractor retaining disc is removed, slowly release the pressure as shown in image.
CAUTION: Ejector springs are under a pre-loaded tension. Take care when removing.
There are four components;
  1. The extractor retaining disc
  2. The extractor (removed in the picture below, this just slides forwards)
  3. Extractor spring plunger
  4. Extractor spring itself (This is the item we are replacing)
5. Simply, remove the plunger and spring. Replace the extractor spring with replacement supplied, applying a generous amount of grease found in your kit and reassemble. Take care to note, the extractor retaining disc has a flat side and a bevelled side. The bevelled edge must face outwards.
Duplicate the operation for the other extractor.
