Well from what info I could gather on the carbon uppers , there is very little info on them.
For the most part it was 50/50 .
Did find some pics of a 9 mm upper that broke in front of the ejection port .
Other than that no real proof of anything good or bad !
AT $200 for a upper reciever, didnt want to find out the bad ,by way of lost cash or eye balls , finger's ,ect .
So I come up with this great weight saving ideal SBR !
Well not only will my AR weigh less so will my wallet
Any who ,pics coming soon to a NFA thread near you .
Thanks for the feed back on my search for information !
