    BCM never disappoints

    What can be said about a gas tube? From a manufacturing standpoint, it is flawless: free of burs, abrasions, and holes are perfectly aligned; it does what it's supposed to.

    Quality product like you expect from BCM. It’s running perfectly fine with my rosco 12.5 carbine barrel and rosco fixed gas block! BCM have seriously some of the fastest shipping even during this corona virus BS. Buy with confidence!
