Stock Status:
The BCM® Extractor Spring is a heavy coil design made for the increased extractor tension required on many AR15, M4, M16 short barreled rifles. This product also improves the reliability on a standard 16" and 14.5" carbines.
As with all BCM branded products, the highest quality is the primary focus. Our BCM Extractor Spring is manufactured by a 9001:2000 facility employing the latest precision equipment. BCM starts with only the highest quality chrome silicon material, heat treats to stress relieve the product and shot peens to add increased strength.
This kit also includes the new black extractor insert, standard on all M4, M4A1, Mk18 carbines and the recent new standard on M16A4 rifles. The BCM Extractor Spring is so strong the Mil-Spec Crane O-Ring will probably not be needed, but it is included.
This kit includes:
- BCM Extractor Spring (chrome silicon, heat treated & stress relieved, shot peened)
- Crane Ind O-Ring (Mil-Spec)
- Black Extractor Insert

    Upgraded extractor spring

    Posted by Cole Knochenmus on Mar 5th 2021

    I haven't run it yet but it really not much stiffer that the one that came in my bolt kinda disappointed if I still continue to have problems with this spring installed I'll probably put the extractor in from my tromix 458 bolt because that one is actually stiff

    Easy install. Used a vise grip to apply pressure and place the pin. Much better grip on the 223

    Upgraded Extractor Spring Kit

    Posted by Steve on Dec 31st 2020

    Bought a used BCG and had tons of failures to eject from a 10.5" upper. The spring kit solved that issue. Only gripe is tax and shipping cost more than the kit - $5 to ship is a bit much for this item.

    Extractor Spring Kit

    Posted by Daniel Roberts on Dec 22nd 2020

    Case slippage or failures to extract? This is your ticket. Remove your BCG, pull the bolt, drift the extractor pin and replace your old springs and post with this setup. BCM kit is the best you will find. Spring is perfect fit with the post insert. Rubber butt hole is an upgrade and may not be needed but if you do use it, it will be a tight fit on the case rim. Reassemble in reverse order and your good to go. Keep spares because your butter finger teammate will lose his rig in the sand. Just sayin'. Peace brothers.
