AR-15 Extractor Spring Question

[AB.boy]

I have a Norc CQA 14.5" carbine, one of the first batch that came into the country years ago. It has run like a top from day one. Out last week and on my second magazine of the day it refuses to extract. Get it home break it down and its extractor spring has broken. No biggie, change the spring. Sourced a 3 pack of the Wolff Xtra power extractor springs. On the instructions it says to something along the lines of 'use with the colored insert that is in your current extractor spring'.

Now in my rifle there was no insert, just a spring. In the manual that came with the rifle the exploded view drawing only shows a spring, no insert. So I assume that is the way these were produced. Have other CQA owners experienced the same thing?

So the question is should I be running a insert with this spring or just the spring alone?
If I should be, does anyone know where I can get just the inserts in Canada?

(Just to be clear I am talking about the little insert not an after market 'D' or 'O' ring)

Thanks.

Try it alone, if it don't work properly just add a rubber o ring, to add pressure on the spring.

The lack of an insert is probably the reason the original spring failed. Inserts like that act as a stress buffer inside the spring, giving it a longer life. A bolt rebuild kit should have an insert in it. It will work without one, but as you've discovered, spring life is reduced.

Buffer technologies has a kit
For 19.99
My opinion is if your ar bolt does not have the Oring and plunger upgrade you should get.
Saskatoon gunworks has them
