AR-15 EXTRACTOR SPRING UPGRADE KIT Reviews & Ratings

The BCM® AR-15 Extractor Spring Upgrade Kit 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. The 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
This is also available in a 3 pack.

Stiffer springs as advertised

These extractor springs by BCM definitely do the job and generally eliminate the need for an additional rubber donut. Unlike the inadequate double spring 308 crap from Sprinco, these actually work!

Would you recommend this? Yes, I would recommend to a friend

Highly recommend

I put these in every BCG I get. If you are wanting to shoot steel case ammunition and not have to worry about stuck cases. Use this kit.
