    Had to hold up to the light at an angle to find the blemishes. Very satisfied with all 3 uppers.

    For the life of me, the blemishes couldn't be identified with the naked eye, and I have four...
    Fit and finish seems perfect, barrel extension and nut mated up nice and snug and meshed well with my lower. More than pleased!

    Blem Upper

    Posted by Billy Bonner on 27th Aug 2020

    I could not find the blem on it. It was in perfect condition. Shipping was very fast. Faster than I expected from a manufacturer. Very nice quality finish not chalky like lesser brands that tend to scuff easily. I have always been very pleased with Stag's products.

    Fast shipping and delivery.
    This is not my first blem item and I have not yet been able to notice the blem. I really have to look hard to find it. I'll buy blems everytime I can.

    Blem Upper

    Posted by Vern on 28th Jan 2020

    I got my upper Monday after it was shipped the previous Thursday, very fast shipping. I am putting it over a Stag lower I got last year and the fit is perfect. The blemish is small, nothing that would be noticed, But it is a good price and I can proceed with my 6.5 Grendel build. Thanks Stag for a very good match in products, even with nearly a year between the manufacturing of them.

    Very minor tool marks

    Posted by Jonathan Winslett on 28th May 2019

    Very minor tool marks. So nice compared to the anderson lower it sits on. Pretty loose fitting but likely caused by subpar lower. Its just a throw around ar build anyways so the tool marks are quite welcomed. Ordered sunday night, shipped first business hour monday morning. Very happy with that.

    Got delivered today. There were no tool blemishes, no physical defects. If anything maybe slight finish discoloration. Oiled the upper and it is absolutely perfect. Happy othes I have had would have obvious tool marks.
