I don't know how Bulldog justify £180 for a pair of spotter arms... the Mirafit M2 arms were £60 and they are absolutely solid, there really can't be that much of a difference. Either way I suppose you get something that's going to last but still
They are pricey but they are top tier quality. 80mm is thicc.
Mira is £100 for 60mm. https://mirafit.co.uk/mirafit-m3-safety-spotters.html
