High quality progressively wound, coated AEG M70 - 0.50 joule downgrade spring from BlackTac with a power of up to 230 fps (depending on the respective AEG and system's tightness)
Some clubs and organizers prefer to set a Joule limit of 0.50 Joule for Skirms. This can have various causes, but most are safety concerns due to confined space (CQB) or poor visibility.
The spring has been extensively tested by us in various AEGs. Typical knife trades with the M70 spring lay between 69 - 70 meters per second .
