Hi,Archers Lowest tube grade D around £1600!!!But looks excellent,able to shoot fox at 200 yards+ Have not Heard of Pulsar challenger,will have a look also,thanks,Debur.
Put link up for ya there is a list of scopes that work good with add-ons, Did you not have a look for a Envis gen3 mono they go from £1000 to £1500 and just as good as a pvs14 and a grand cheaper. They don't look as nice but they do there job very well for the money.
