trim one coil out of the new one that you got from gunjunk corp.
i avoid parts from that supplier unless i have no other option.
the parts you get may be rusty, over seas made, or just the wrong part.
they have people that dont have a clue about firearms taking orders.
i buy spring stock from Wolff springs, and trim to match based on the rate.
that way i can play with the rate, and feel.
you can get a good supply from them for about what you paid for the shipping with GP.
