050806109537 Lower Receiver Vise BlockToo fat to fit. 04/07/2018
Vise block required some careful filing with a wood rasp to fit. Not a difficult job. Quality (fit & finish) of this item is less than what I expect from Brownells.
Great Potential but Flawed Design 13/04/2018
I purchased this block in the set with the upper clamp, due to it's popularity, although I've noticed most gun smiths seem to be moving away from it. Once home, I discovered that the lower block does not fit into any of my AR lowers, which covers 4 (top) AR models. Looking at the shape of the block, I can see that it is concave (wider on the ends). It's not just snug, it doesn't fit at all - any of the lowers I tried. Reading more about the block, I learned that it does require fitting before use. That means in order to use this tool, I have to permanently modify it's shape. No tool should require permanent modification before it can be used; that's a design flaw. Fitting custom parts makes sense...but a tool? My concern now is if I modify it enough to fit 1 lower, that might not work for another. I'll possibly have to modify it for each lower, but once you take material off, you can't add it back on. I'm tossing this in the junk pile and already ordered a competitive product. I'm giving this 2 stars, because it doesn't work out of the box, but seems like if it did fit your lower, then it would be a strong vise.
