Can I get the correct factory part number for a semi auto Colt disconnector spring? Some of my colts have a black disconnector spring. Some of them have one thats almost red in color.  One of the carbines with the "red" colored disconnector spring is giving me some issues. Doubled once and hammer failed to reset once as well while shooting.

I'm going to replace the disconnector SP63157 (.170") but cant figure out which is the correct disconnector spring on brownells website as it lists two or three Colt disconnector springs.

SP63026

Both the disco and spring are out of stock.

Thanks.  You dont happen to have a brownells item number for it do you?

Since brownells is out of stock on the colt parts I just used a spare Bushmaster disco spring i had.  Appears to have solved the doubling and other trigger group malfunctions I have been experiancing.
