My 2nd DLC BCG from CTac
I have one of these that I used for a SBR build. Once these were back in stock I ordered a second immediately to replace the milspec BCG in my WOA upper for p-dogs. Super slick, clean up great, and the logo on the side is trick. Highly recommend.

Update on my FTE issues
After comparing ZQI , Federal American Eagle and steel cased/poly Russian Ammo using the ion bond BCG I have concluded that the ZQI ammunition was at fault for the FTE problem. ZQI ammo is too soft and actually deformed when the extractor tried to grip it. Federal and Tula function perfectly. 600 rounds have been fired with no malfunction unless I used the ZQI ammunition. My Stag Arms BCG will extract the ZQI ammunition more reliably with a 1 in 100 FTE vs the Ion Bond BCG 1 in 60 FTE In the end I do recommend the Ion Bond BCG it functions great. Super easy to clean, shows very little wear after hundreds of rounds fired and the cobra tactical systems logo looks bad ass when the bolt is closed.

Lots of FTE
I bought this BCG for a 300 black out build. Since the rifle is not yet finished I ran it in my stag arms AR-15 stock s3 model. Within 75 rounds the rifle had a FTE then again at 80 rounds. When I switched Back to the stag arms BCG I had no problems. I cleaned the rifle and tried the cobratac BCG again and within 60 rounds FTE. Otherwise the BCG is easy to clean and I do mean easy. I'm still trying to determine what causes the FTE issue not 100 percent sure it's the BCG from cobratac but it only happens when I use it.
