Excellent Upper
This is my second upper from Grid Defense. My first one is a 16” 5.56 and she is going strong after thousands of rounds down range and I’d put my life behind it any day. I expect this 10.5” upper to be equally as well made and will update this review when she has been put through the paces. The finish and quality are second to none in my opinion. Why pay more for great products that work the same? Cheers!
