Description

Sometimes your replica is just shooting under the FPS  you need it to be at. For those cases where you need to dial in your power to exactly where you need it to be, try some of these ” Airsoft FPS Booster” Spring spacers. By pre-loading the spring under additional tension you can squeeze out some extra power in situations where the next spring up will be too big of a bump. With their modular nature a pack of three can be used to dial in up to three replicas.

Dimensions:

ID: 11.4 mm

OD: 14.5

Thickness: 3mm or 5 mm

Designed specifically to fit CYMA PLATINUM QBS spring guides, it will fit most QD spring guides as it it designed to cover the entirety of a spring.

Each spacer should add between 3%-5% power per spacer.  Sold in packs of 3 for an approximate gain of 10-15% power increase depending on thickness can be mixed and matched upon request
