I'm looking at various bullpups around the £500 mark. This will be the first - and maybe the last - I buy, so I'd be grateful for some pointers please.

Rifles on my shortlist are

Artemis P15
Artemis P35
Kral Puncher Breaker
Stoeger XM1
Reximex Regime

All will be in .177 cal.
Has anyone strong views on any of the above? - positive or negative. Other suggestions considered too.
I have yet to visit my RFD to see what feels good. Obviously this will be a deciding factor for my gibbon arms.
Cheers.
