When installing the buffer tube to the lower receiver at the proper torque of 40 foot pounds, it has always been a pain keeping the tube from canting or stripping threads. This jig works perfectly and can also be used as a gauge for testing completed rifles..

Looks good.
I went a different direction and started useing ratchet lock castle nut/end plates. No more high torque needed and no vise block needed too do up the buffer tube nice and sqaure to the lower's centerline. Just eye ball it and a quick snap with a every day castle nut wrench and she is nice and tight and never coming lose.

I've used mine for both traditional castle nuts & the ratchet type nut/plate for carbine buffer tubes. Didn't notice buffer tubes being out of alignment. The thumb screw under the rear clamp can be adjusted to even things out. The rear clamp doesn't have to be real tight either. Finger tight on the thumb screws is sufficient. I've also used it to install rifle buffer tubes. Torqued the buffer tubes to 35 ft lbs easily. Don't even need the clamp. Wish I had one of these years ago...I refuse to be victimized by notions of virtuous behavior.

Tighten the receiver to the front via grip screw, then tighten the 2 top screws for the top bracket that holds the buffer tube. If a person then tightens the back bottom screw with any amount of force, it will pull the buffer tube down and possibly bind the castle nut against the end plate. I eliminated any possibility of binding by putting spacers between the back bracket and base. It is now permanently put on a perfect plane after tightening, eliminating any possible binding...It is quite easy to measure with a caliber when tightening the bottom thumb screw the amount of bend the bottom adj screw can create.
