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.

Reviewer: Tcb from Houston, TX United States  
This product is very light but well built and sturdy, I like it so much for my new upper 300 Blackout 9" on Sig 516 SBR lower that I will be adding another rail to my Windham CDI 16" AR!! I also ordered the bolt and charging handle which are also awesome quality parts!
Well made and thought out, exceelent key mod rails too. I will be shooting soon!

5 of 5 Great Price & Fast Shipping October 17, 2019
Reviewer: P. Hightower from Jacksonville, FL United States  
My first AR was a Daniel Defense but they don't stay ahead of the curve. I replaced it w/ a 14.5" ELW-F KMR upper.
Because of that upper I recently bought a 9" 300Blk upper. It's everything I expected. BCM rifles, upper and parts high quality and ridiculously well priced. No matter your budget, BCM should be your first choice.

5 of 5 Great product, well built, and runs great May 8, 2019
Reviewer: Anonymous Person from DALLAS, TX United States  
This is my first 300 Blackout, and I love it.  This is without question a quality product.  

Shipping was fast and arrived with lots of promo items (stickers, catalogs, hat, etc).  I do recommend BCM, and will buy from them in the future.

5 of 5 Love It October 27, 2017
Reviewer: Anonymous Person from GA United States  
Used this as an extra upper for my 300 blackout.  My other upper has an infrared scope so I put an eotech with magnifier on the BCM.  It is lights out accurate.  Carry it with me when turkey hunting since I see more wild hogs than turkey.
