788 mags in 6mm Rem are very hard to come up with. the factory ones used to bring $90 if you lose yours. Fella told me awhile back that some outfit started making them for about $55 ea. I looked for a good right handed one for years,saw a few but the owners were too proud of them ,finally ended up with a used M77R for less money than it would have took to get a 788. Saw a beat to hell one with no finish left on it in 22-250 awhile back for $275, makes me smile everytime I see one cause that one was the hardest used outfit I ever saw. The previous owner had pop riveted a 6" length of brass toilet tank chain to the bottom of the mag and wood screwed the other end to the side of the stock.Guess he bought one to many mags for it LOL.
