AR bolt catch spring problem

[Plisk]

I'm trying to install my bolt catch at my AR15, and the spring for it doesn't seem to fit into the hole for it. One end of the spring, the last 2 coils are bigger and wont go in one end, and if you put it in the other way, it goes in all the way but the larger coils prevent it from going all the way in. I thought maybe I mixed up my disconnector spring, but i tried to install this spring on my disconnector, and it doesn't function. So I've got the right spring, but I have this problem. Can anyone help?

It sure sounds like a disconnecter spring.

The flared end should be inserted down in to the trigger portion and it will take a little pushing to make it fit.

The bolt hold open spring should have no flare.

You're using the wrong spring. The spring you describe is for the disconnector. The bolt catch spring is uniform in diameter.

Did you place the spring in, followed by the bolt catch buffer?
