Nice piece of machining but not a straight forward fix as the clamps on the bottom are too tight so spent a good three hours fettling the fit. If the clamps on the bottom are tight they will not allow the clamping bolt to tighten up smoothly with risk of cross threading the nut and ruining the new rail just purchased.

Having ordered this twice on other sites only to then receive a phone the next day telling me its out of stock rainbow conversions came up trumps. Next day delivery and excellent customer service
