Need some help placing a value on some UZI accessories

[OkcPuckfan]

I ran across a cache of Action Arms magazine clips and magazine loaders, still in the boxes. The magazine clips are the clamps that hold two mags together and the loaders are straight push down loaders. They are in white AA boxes with three descriptions (the third is for a front site tool, unfortunately there were none of these in the box).

Any ideas as to what these are worth? Trying to decide if I should buy the lot and offer them up here.

Thanks!
