The Bravo Company Manufacturing 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. 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.

"I built a 300 blackout pistol a few months ago. On my second trip to the range an issue developed. The bolt would pull the spent case halfway out, the extractor slips off the case then the bolt would feed a new round and cause a jam. The issue is due to a weak extractor sping, this kit fixes that. AAC sells their 300 BLK firearms with this style o-ring."
