The Walthers get good reviews for a budget rifle -

I’ve seen too many AA thin barrels bent (though usually easily fixable) and they are a good simple design
I prefer BSA and prefer older s/h and then JB blueprinted so I guess my BSAs are custom spec. I prefer the sturdy barrel planted well into breach block

There are plenty of Webley Raiders around too and old Titan/ Falcon rifles - all good budget bets
