Perfect USGI Barrel nut wrench


This is the 3rd VISM tool I’ve purchased. And just like the others, this tool does not disappoint. It is extremely well made and very affordable. It makes installing the Delta ring barrel nut significantly easier than the traditional wrench when also using a torque wrench. I strongly recommend using this wrench over the basic multi purpose AR wrench. Shocked there aren’t any other reviews.
