It was not as advertised - Tiger Rock AR-15 Ambidextrous Tactical Charging Handle

It installed into my delton Echo 316 m and the first time I let the charging handle charge with the natural weight of the buffer spring it locked up my rifle made it so that I could not charge my rifle due to poor choice of materials. If you cannot pull the charging handle back on the firearm because it is locked into place that renders your weapon useless.
