Hello everyone,

As an owner of a Specna Prime airsoft gun, I'm limited in my local games to either 1 joule or 1.2 joules.

I know that the combination of the high-end gearbox and the brushless motor makes the Prime models competition-grade replicas, but I understand that this can be a disadvantage when their power needs to be reduced.

Ideally, I'd like to be able to play in either M90 or M100 mode. The M100 produces 1.2J, I imagine the M90 ​​will go down to 1J, BUT I don't want to risk damaging the replica in any way because of these regulations...

So I looked at the springs and noticed that Specna offers several sizes for the same part number:

and

https://gunfire.com/en/products/m100-specna-arms-main-spring-1152221038.html

With two different sizes. I'd like to know why this difference and which of the two would be the most suitable, and why. Does anyone have any explanations? I can't find anything on YouTube or here, unfortunately.

Regarding the M90, there are also two versions, like the M100:

and

Again, there's a difference in size and price!

Would this size difference allow me to use it without risking damage to the replica, while still maintaining the responsiveness of an 11.1v LiPo battery?

Thanks for your feedback.

See you on the field! :)
