Umarex H&K MP5 A5 TAC SPRING
 

Hi,

Does anyone know what default spring the Umarex H&K MP5 A5 TAC (made by G&G) comes with? I'm guessing a 110 but want to be sure before I order a softer spring.

Thanks.

I'd chrono it once you get it. Its shooting near CQB limits already. You may find you can leave the spring alone.

Paperwork called for 370 but after testing, it shoots at constant 350fps 0.20
I won't have to downgrade the spring after all ^^
