Solid upper vise block
For a stubborn barrel nut, this supports very well and doesn't put all the pressure on the upper receiver lugs.

AR-15 Upper Receiver VIce Block
Worked perfectly on BCA Right Side Charging Upper Receiver. I was able to swap out a Pistol Receiver Extension for Mil-Spec (Six Position) Carbine Receiver Extension without any issues.

Best upper vise!
Nothing else worked on a MilSpec, L.H. Flattop Upper, even clamshell blocks from other manufacturers that were advertised as working on them. After several purchases & Returns, I found this. PERFECT!

Lock it up
I recently purchased a product from Brownells & it was just what I needed to finish a project I was working on. The until is made from a hard type of polymer or plastic but it was solid & never gave up. I'm glad I purchased this great piece of gear which was also very simple to use.
