Any one know where I could buy a upper receiver vise block? I have a billet Hera arms upper that won't fit into the normal clamp style block that I have, so I am looking for one that pins into the take down and pivot pins. Preferably Canadian dealer, and before any suggests Brownells they are sold out of this style. Any suggestions would be appreciated.

Thank you
 
Another thumbs up for the Reaction Rod, much better than the vise blocks (I have both types) for working on the upper.

I have seen these around but never looked to much into them, but looks like a much better system. Unfortunately arms east is sold out according to their website, so will have to go through Brownells.
 
Brownells has a version of the reaction rod for sale for 37 bucks. I might have to pick one up. Are tools an ITAR item?.

Not ITAR so go crazy. What's the part number? :)

Have not used the Geissele one.

I own the Brownells one though. Bought it local (Calgary) from ATRS. They prolly have more in stock too. Just give em a call.
Fantastic item

The brownells version appears to be quite a bit shorter which would make it more difficult to secure in a vice.

If you watch the video on the brownells page you will understand what I mean.
 
Geissele version is made to be secured in a vise, Brownells is made to be used with a socket wrench. Watch the video.
 
Just used my Geissele reaction rod for the first time a few days ago and it is a sweet tool to use, removes all the force of torqueing the barrel nut from the upper, I would highly recommend getting one, it's worth the money.

It does not. All the force is put on the indexing pin, which in the opinion of people who have forgotten more about the AR than I will ever know think it's a bad idea.

You don't need to spend a ton of cash for a single upper build, a vise and two blocks of hard material one on the top and bottom of the upper put sideways in a vise is a good method. People, including me, have been using this method for a very long time with success.

What do you use for blocks? Wood?

I've used oak and I've used teflon blocks too. Anything perfectly flat/parallel, solid and strong can do. It's not rocket science, you're just keeping the assembly from shifting/twisting/moving, very little torque is needed to keep it from moving around.
 
Humm, good point Dietz. I figure it would be good to have that for tightening on a flash hider/muzzle break but then again, you don't need a whole lot of torque to install those. I guess I'm a gear junkie.

I got one of these upper blocks:
