View Full Version : New Extractor upgrade install
Just got my Extractor upgrade with black insert and O ring, how do I take out the blue insert and where does the rubber O ring go? Thank you!

Pull it out with your fingers (or needle nose plyers). Put the black insert in the spring and position it over the hole on the extractor. Take the needle nose and crimp it into the hole. Then push the o-ring over the spring.

Thanks for the reply. Just installed it without the O ring. Way too tight. Once chambered the round the BCG got stuck, could hardly pull the bolt back. Once the round ejected, you can see the extractor "ripped off" some brass from the round. Had to convert back to the "blue" set up. What gives?
Fire it and see how it does before changing it back. If it gives trouble leave the black insert in and the higher power spring but leave the o-ring off.

just curious, but did your upgrade kit include an extractor spring upgrade as well?
Shihan,
I didn't put the black O ring in.
Mean,
Yes, the package includes black insert, O ring and high tension spring.

I have seen this one other time to date. Try the black insert with the old spring and the O-Ring and see what you get.

Mine went in so tight that I had to use a clamp to push the extractor down to get the pin installed. If you ride the charging handle it won't close over the round, and the forward assist is a no-go. But it closes fine when dropped from the bolt hold open or when the charging handle is released from all the way back. It closes fine when firing the weapon, too.

Can I get away with just using the blue insert and adding a D-fender ring?

Actually the manufacturer of the "D Ring" suggeted to me , Black Insert and "Standard Spring".
I just went through all of this same stuff...and my 16" gun ran 100% before I started F------ with it.
My combination on a 16" mid length upper is a standard spring, and Black Insert. No donut, and no D Ring.
Most have educated me so far as to the fact that a lot of the "Extractor Upgrades" are meant for barrels that are shorter than 16".

Actually, the extractor upgrades are for carbine gas system barrels.
The mid-length does not extract nearly as hard so it does not need the extra extractor tension.
A good spring is all you need.
A black or blue buffer or an O-ring or d-fender, won't matter...
If you do not get the spring seated deep into the extractor groove with the needle nose pliers, then reassembly is really, really tight.
I just went through this with three different AR's. If the spring wasn't seated then the extractor just held the round and would not release.
When seated everything was great. Just my .02
I run an "upgraded" extractor setup in my 16" middy here.
I don't "need it" most of the time - but in times where I have to put up a high volume of fire - I've never had a FTE.
Before the upgrade on a few courses etc. once the gun got hot it would have FTE's.

Kevin...
Interesting.
I use an LMT MRP 16" Mid Length, and when I put the heavy duty spring, donut and black insert in the gun, it would eject the rounds only about 1 foot away at 3:00. Pretty much landing just next to my right foot (hardly getting out of the ejection port, and some wouldn't extract at all. But I didn't replace the EJECTOR spring which had about 4,000 rounds on it, which may have been the issue.
With just a Mil Spec. Spring and a Black insert, the brass ejects about 7-10 feet away, at about 3-4:00 to the right....every time. And yes, I did put a new EJECTOR spring in the bolt.
I could go back and try the upgrade lit again now that I put the new Ejector spring in, but the gun isrunning so welll,,,AGAIN, that I don't want to mess with success.

I've got one standard length carbine gas system and one mid length. Sounds like I can upgrade both with one kit.
Stiff spring in the mid length and the black insert & O ring for the short one. I'll be damned if I run one with an ejector so stiff it won't chamber properly. In that case something is going to wear that is not intended to.
