hi pal
to get a decent pcp setup,do lots of reviews on diffenrent rifles,alot like the air arms s400,s200,s410,also the bsa ultra a good one i just recently brought one,then your need a pump or diving bottle,pumps around 150 same as bottles,d what method of cocking do you want as bsa ultra has a mmc-fore arm plunger and not a cocking pull back,scopes the ones you have said will be fine,
ive only had my pcp ultra for a few days now my first pcp so im still picking new things up,
anyways buddy good luck
