Just finished making a vice block, got the idea from a picture of one for sale. I think just about anyone could do this. I do have a drill press, that and a file is all you really need for tools. It took about an hour to make. I used a piece of scrap Corian, it is incredibly strong. I made one pin from a 1/4 inch bolt and will use a 1/4" awl for the other end. It has a nice point and really presses the block into the upper pin holes. You can get scrap Corian from most any counter top place, mine was from a sink cutout and is 1/2" thick. The outside dimensions are 2" by 6 3/4". It fits in my 5" vice easily.

It's holding the upper via the takedown pins, just like the DPMS Panther Claw tool. However, the DPMS has a bunch of plastic cut to fit inside the upper receiver to put less stress on the holes/lugs. I don't think I would torque too much on the upper with the upper just held by the holes like that. |
I watched a guy break a receiver while removing a bushmaster barrel nut with a setup JUST like this. There are some jobs that this block works great for, mostly installing sights, scopes, gas blocks and freefloat handguards AFTER the barrel nut is already torqued into place. DO NOT torque barrel nuts in this setup. You still need a proper clamshell type block for that. Brownells Link |
