The garbage - BRG 5.56mm/.223 Complete Bolt Carrier Groups

This product was cheap enough to try. Got it in and the bcg was in 2 pieces. The bolt itself wasn't in the carrier, found out the rings were hitting the inside of the carrier and bending. I replaced the rings, went in fine. Got it together, put in rifle, started shooting. The extractor was not letting loose of the spent casing. Jamming every shot. Had to pull handle back and hold it while releasing the mag and using my finger to push the casing out. Took bolt apart again, and the extractor does not budge at all with our alot of pressure and using a tool.completelt out of spec...
