3 of 5 Upper receiver June 28, 2021
Reviewer: Tim Wooten from Oakland, OR United States  
Product looks good. It successfully mounted to my lower. It isn't the greatest fit, definitely has a rattle. Ill certainly need to get a receiver wedge or something similar to get a good tight lock up. It arrived today, have not had a chance to test fire yet.
