    Bought this as a blem and had to search to find the blem. If it were up to me it would not have been a blem

    I’ve always been a happy customer when ordering from Stag. The stripped uppers work great for my builds. Can’t say enough good things about both the product and the company!

    Upper Receiver

    Posted by Gary Graham on 9th May 2021

    as a Master Armorer I have been building M16?AR15/M4 Series rifles for 35 years, and nearly all my personal AR's use Stag lowers and Stag Uppers. If I had another6 I would use them right away for some stag lowers I have laying around for future builds. I have never been disappointed by STAG. always to spec, and nice and tight where it counts.

    The machine quality is excellent. Dust cover and forward assist installed without fitment issues. This will make a great build.
