What reflex sight for a Taurus Revolver

[Zero58]

Hi all hoping I'm in right section for this post if not sorry.
As in title I'm asking for advice on what one to buy I am buying a weaver type mount for her... her being a .22 Taurus LBR, she will be used for local club comps nothing higher as I'm not that good a shot !! but would like to acquire a average score at club level.I want the refelex type as I want it to fit where rear sight would have been also to keep weight down I will be shooting at a target at 25meters I do under stand MOA but what can I get in the uk for £100 make,model, MOA if possible. I have shot a red dot with MOA of 4 which seem to cover the black of the target so what do you recommend and why...
Best regards Frank
