Just ok. you get what you pay for with bcg’s - TRYBE Defense Mil-Spec AR-15 .223/5.56/.300 AAC Complete Bolt Carrier Group (BCG) BCG

Lots of tooling marks in several areas, including the bottom of the carrier where it slides against the hammer. Using this BCG in a new build with a quality 16” barrel. Very first round failed to feed and jammed the round between the bolt face any front of the charging handle. Had to use a tool to push the bolt back to get the round out. Had not even fired a single round and was dealing with a significant failure. Once I got it running it experienced the same type of failure 3 additional times in 40 rounds. Will polish do some cleaning/polishing/lubing and try again. For reference, I used a bolt out of another rifle and had zero malfunctions.
