Course there isn't

Why would a top UK manufacturer produce a break barrel springer to suit UK sub 12, to be the ideal field rifle and to knock the badly flawed HW99 off its perch ? A perch that is now even busier with the little HW30 becoming more popular .

Why would Air Arms fail to see the lack of quality product in this sector of the market and yet not capitalise on the opportunity ?

Well I for one have just asked them. On the Air Arms website there's a contact section under "support". Why don't you ask them too ?

There are many lovers of the 99. But I bet each and every one would rather have a rifle that was designed properly from the off.
This size of rifle is something sadly missing from my small collection of rifles and will stay "missing" until someone makes one properly.
