PDI 13mm VSR 140 spring review

PDI 13mm VSR 140 spring review


The parts were supplied from x-fire.org which are the official distributors of PDI products from Japan. There customer service is superb and with juggling shows and meetings the sales manager managed to help me out very quickly and helpfully.


The item was superbly wrapped and no damage was present to the inner package. The items were all wrapped in a layer of bubble wrap and then any loose space was filled with little sausages of bubble wrap. They were then placed in a cardboard tray, covered in another layer of bubble wrap and then covered in a final layer of brown heavy wrapping paper


Item was shipped via EMS and was superb, within 2 days the item was within the UK and then the following day it was delivered to my door. The tracking service was kept fully up to date with its progress.

1st Impressions:

Excellently made spring evenly spaced coils and very stiff, about the same length of a normal spring but stiffer.


Very easy to install into the cylinder set as the spring needs little compression to get the cylinder head onto it.

FPS test:

The results this spring gave are follows:

  • Shot 1 – 443fps
  • Shot 2 – 445fps
  • Shot 3 – 439fps
  • Shot 4 – 443fps
  • Shot 5 – 446fps

The results were produced with 0.20g ammo, a tm hop rubber and EdGI 6.01mm barrel. The rifle was tested on a Guarder chrono.


Excellent spring and gives consistent results. Has had about 100 rounds through her now and still consistently shooting an average of 444fps.



Consistency of fps: 10/10

Value for money: 9/10

Construction: 10/10
