    Ordered 6 days ago and was told it wouldn’t ship for 2 weeks. I was ok with that from the start, but it got here in just 5 business days! Slapped it on my lower I built last week. Ran 3 mags (1 subsonic 2 supersonic) through it with zero problems. Wish I’d have heard about this company years ago. This will most definitely not me the last time I order from them. Top notch product and a VERY fair price.

    This is my 2nd upper from CBC. Even with the weather here in the Northeast the shipping was very quick, about a week. The fit and finish look awesome and I’m looking forward to putting it on my new SBR build. Great job CBC!
