OP if your only paying £1100 for a dedicated .22,then i can
see it only being basic entry level rifle.......to get that rifle
up to a decent level with optics etc then its going to be
nearer 3K.......Lantac are ok,Wayne at NWC makes up the
Spikes. but remember Spikes no longer make the ST22
due to poor quality control of their bolts several years ago....
Bradley Arms are good if you dont mind the long months wait
for a .22
Genuine Eotech from Viking at £1300

So OP if money is not a problem,then £600 for the super
reliable 15-22 is neither here or there..........but be warned
carrying around on your "hunt" an all metal AR type rifle fully
loaded with optics is no light weight matter
