Thank you for your response Jon.
"Dual port as standard" good stuff. and glad you can reassure me regards 600mm being "fine" for slugs.
If the guns can now handle 300bar, you (FX) may as well make hay regards shot count claims and supply 300bar bottles as standard, this could also save you from being accused of aftermarket profiteering
Slug power kit , for me, A gun that shoots slugs great at long distance and Pellets (at shorter ranges) reasonably well is the holy grail, Not sure if the aftermarket "kit" would provide that, however that is me and (maybe) not the masses, so fare play on your reasoning for not including it as standard.
Again thanks for your response, very professional as always, FX may get my Pennies as yet.
I bet you sleep better knowing that
.
good luck.
