So I recently got my SRS A2,
currently got an SA Fasthop with Chub Nub and running a Rapax 2 Joule spring and getting about 2.1 Joules with 0.43g BB's
I've ordered a variable mass piston to get it to the magical 2.3 Joules, anyone else got a similar set up and know what weight they are using the VMP at?
