upper vise block by mike, Verified Owner, December 31, 2022
I just received this and haven't used it yet. I am sure it will work as it should. I was disappointed to see that the product was made in China. It makes me wonder if I could have spent less on one without the Wheeler name on the packaging.

I had to grind out two spots in order to fit a left handed Stag upper. Even though the packaging says for left and right handed. This was not difficult but was a little frustrating as it just added time to the assembly of the upper.

Just as described by Jew joo, September 7, 2021
Great addition to my gun tools. I used the vise block to change the barrel nut on my AR. Worked flawlessly! Be careful when handling outside the vise,there is no latch mechanism so one could easily drop an upper if careless.
