    This kit will upgrade every Bolt Carrier Group you install. Upgraded extractor and spring is evident after 1st pull of trigger. If performance and safety is important to you, get 3 kits. 1 to install, 1 back up and 1 for your buddy.

    Good upgrade

    Old bolt wouldn't extract 300 blkout casing after firing. After the upgrade kit it hasn't missed one yet.

    Easy fix back in action

    Posted by Russ Schreiner on Jul 6th 2021

    I’m not a gunsmith by any stretch of the imagination but I was able to get my gun back up and running in 30 minutes. I’m ordering an extra to keep in my bag just in case. Easy fix at a very reasonable price.

    Bolt Mod spring and extractor upgrade

    Posted by George Evans on Jun 23rd 2021

    As with all BCM accessories, perfect fit and function. The spring upgrade alone is worth the price of the kit, but knowing I have a set of gas rings and a new extractor when needed - and they are all BCM - is icing on the cake. I have ALL BCM furniture and available accessories, from stock, to grip to aftermarket foregrip to mounts, springs and a BCM charging handle. So to call me a fanboy is probably an understatement.

    The first upgrade you need.

    Posted by Brandon Russell on Feb 21st 2021

    This kit is a must for an upgrade or as a spare for backup. This is the best extractor I've found. I only use the insert and spring it's been working flawless through a "few" rounds.
    Money well spent!

    Just thought some spare parts was a good idea, especially the extractor.
