I have some of the Sprinco CS black 5 coil HD springs and they work great. I bought them as a kit with the inner buffer and o-ring. I don't use the o-ring.

i always buy sprinco buffer springs and just add the extractor spring with it. Never have issues, i think it's one of the most valuable upgrades for the AR platform

Best for what? I've never had a problem with any extractor spring in any AR I have ever used.

Factory Colt or FN "gold" extractor-spring, with insert. Cheapest too, dollar for dollar versus the other clones on the market. No need for an o-ring..........

On my 3 carbine gas system carbines I've been using the BCM extractor spring upgrade chrome silicon but not using the O-ring, for over 5 years now and I'm expecting to not change it, should last as the life of my Colt bolts (10K to 60K).
With my midlength and rifle gas systems I'm using the Colt gold extractor springs with mil-spec O-rings, but I replace them from 5K to 8K rounds to avoid any problems. |

Sprinco makes the best springs in the industry IMO.

Your bolt will need to be replaced far sooner than the original usgi extractor spring.

How about the o-ring? My AAC has a green o-ring which they say is supposed to stay soft to lower temperatures than the black ones. Any knowledge on these?

Change the extractor spring. Erratic extraction on brass? Same answer. Grendel and .223/variants. My friend had two Grendels that wouldn't cycle steel at all. Single shots, both of them. Two Wolff springs and both are running 100%. Every gun I put together now gets one before the first shot is fired, why wait. |

I upgraded my 17 year old Bushmaster with a BCM extractor spring and it now flings brass with authority. Didn't even bother with the intalling the o-ring. With all these HD extractor springs nowdays I don't see how there is even a need for the silly o-rings anymore.

The Mid should have an easier time extracting but you put the O-ring on them. The O-ring came about back when they were still using the same spring and insert as the original M16. I never liked the O-ring and saw it cause problems too many times. I used to use a fresh spring and black insert, now I use all Colt copper with supplied insert. |

Best for what? I've never had a problem with any extractor spring in any AR I have ever used. Same here. I don't shoot high volume, though and don't shoot weak ammo that might need stronger extraction, though. For most of us, it seems to be a solution looking for a problem that we don't have. USGI mil spec quality is all I need. Time tested and proven. |

interesting thread , i was cleaning my gun the other night from an outing a couple of weeks ago and found this. i put a franklin armory bfs trigger in the gun a while back and have been beating on it pretty good lately. i don't know how long it's been broken but the gun has been functioning fine. this is out of a bcm bolt , i don't know how many rounds but it's in the thousands and not hundreds. i guess it's time to check and replace the gas rings
