BCM has taken great care to ensure the best possible performance and interchangeability. However, due to the large operational range of 300 Blackout ammunition in the market place, BCM cannot guarantee function will all ammunition types in all conditions. These barrels were designed to run with a carbine buffer with subsonic ammo and a H3 buffer with high velocity ammo. Fine tuning may be required in limited instances based on ammo and buffer choices that work best for the desired application. BCM also recommends running the Crane O-ring (provided with all BCM Bolt Carrier Groups) over the extractor with 300 Blackout.

Impeccable Service, swag and more! June 4, 2019
Reviewer: C.C. from Loveland, CO United States  
Online shopping is easy, BCM makes us even better! Simple navigation on the website. Order was placed on a Sunday, was enough by Tuesday and delivered Saturday all standard service level and almost unbelievable! Then loaded with swag, BCM print magazine, posters, stickers and a BCM Hat that was immediately my daily wear! 100% would order again and suggest anyone in the market do the same. You can’t beat the service and the hardware speaks for itself and is next level as well!

Solid Purchase April 10, 2019
Reviewer: Just a civilian from Jackson, MO United States  
Had my eye on this for a while and knowing BCM's reputation for reliable-well made products I made the leap and I am so glad that I did. The 300 blk upper exceeded my expectations. Simply put...this is an exceptional product from a great company and from my history of using BCM products I can confidently and enthusiastically endorse this product.  Plus I got lots of free swag such as a baseball cap, calendar, poster, and decals. If you are on the fence about a BCM product I urge you to give them a chance, they do not disappoint.

BCM is the best April 10, 2019
Reviewer: Kevin Kulow from Westfield, IN United States  
Beautiful upper, Love the BCM logo everywhere and the 300 blackout above the ejection port, after all when you’ve got a bcm, you want people to know! They also loaded the box up will all sorts of goodies, stickers, gunfighter calendar, gunfighter magazine (for reading, good articles too) will definitely be building more BCM’s
