Brownells USA The right tool for the job 01/03/2017

Very thick steel. This is what you want to remove those castle nut especially those that were staked by Colt. Can also be used on rifle receiver extension plus what's nice is there's a 1/2" drive for torque wrench. Not all receiver extension wrenches will have it. I really liked the 4 notches of the wrench how thick they were made really extending more on the notches of the castle nut. Get it and you'll be glad you did!

Definitely recommended

Brownells USA 3rd time is the charm 03/08/2015

This is my 3rd wrench. Too bad it wasn't the first. Fits both Stag and DPMS nuts. It's short, but I think that is by design. Longer might lead to over-torquing. By being short, it encourages me to use a torque wrench for leverage.
