BE AWARE per Sprinco's website, use EITHER the spring insert OR the o ring in conjunction with the spring. Do not use both.
'Atsa tight extractor!
by Al Bundy -
Immediately noticed the difference in my ejection pattern after installing the spring and o-ring. These are a MUST for any bolt
Strong spring
by Brand -
I have heard lots of good things about these spring co springs. I got them to up grade the one in my BCM, BCG . So far it's been clutching those rounds and flinging them . It has helped my ejection angle. Running a 7.5" barrel

If you’re not rocking this in your AR you should be. If you upgrade nothing else - this is it

Sprinco does a great job with their products.
Works very well

After shooting and cleaning my AR’s I’ve been replacing the extractor springs and adding the o-rings around the springs. These extra power springs and o-rings greatly improve extraction. The extractor holds the cartridge and empty shells much better. It makes the gun much more reliable.
