Before the purists yell at you, what you are looking for is a magazine not a clip.

The only thing you can really purchase for that is what Browning offers and if it came with a 3 round mag. that is prob all you are going to find for it. The hinged floorplate really doesnt allow any longer mags. to be attached to that rifle so what ya got, is what ya got pretty much.

The best thing to do is prob just sell that gun(to me) and go get yourself the Sako with the 4 rounder--J/K -sorta.
