i bought a used set of NSA Pro-mag RR's to replace my SA Crane Golds however I didn't get the poly locks with the Pro-mags. Can I use the Poly locks that came with the Crane Golds? Is there any differance between poly locks or are they all pretty much universal?.......Thanks

 

my pro mags came with the allen set screws on the adjusting nut. didnt have poly in em. the ones u have may work but im sure comp cam would recomend u use the style nuts that come with there rockers.
