Upper Receiver vice block suggestions?

[00tec]

Installing a barrel onto a billet upper (JBO Spartan) and need a method of holding this thing down. Cant afford a reaction rod for my uses, but definitely need a solution.
Anyone have experience with something like this, or another recommendation?

Borrow a reaction rod, or sell the upper and get one that fits the standard uppers.

I just installed a barrel and rail on a MUR... Just used a standard vice block, tightened it down a good bit in the vice and bent the block around it, and went at it. It turned back and forth a little in the block, maybe 20*, until the rail stopped it in either direction. I figured wrist case I'd break the vice block, but it worked out ok.

WADR, I would skip post #3. The whole point of the block is to distribute the stresses so you do not bend the aluminum. Making do is a good way to jack up a receiver.

So, I don't know anyone with a reaction rod or similar and I prefer to not borrow tools from those I don't know well, that's out.
This is a build with a nicely matching billet lower. They're going together.

Drive up here tomorrow after 11 before 12:30 and get it taken care of. If you work weekdays be here 10 on sat morning.

There you go. :)

The Army tech manual TM 9-1005-319-23&P has it done by clamping the barrel, not the receiver. That might be an easier way to do it.

+1 for jim. If I were you I would take him up on his offer.

Logistics suck for me. I don't have a good time to meet any of the guys that have offered assistance (Thanks again!).
I really need an affordable tool I can use at home. I may have to piss off the accountant and get the Brownells version of the reaction rod if I cant find something more affordable.

DON'T unless you have a good vice with pipe clamp jaws. The brownells does not have flats like the GEISSELE

It could have flats. If a guy had a decent grinder handy.

According to the manufacturer, it doesnt need them. There is provisions 1/2" ratchet/breaker/tq wrench. The barrel nut wrench is what actually gets clamped in the vice. Torque is applied with the torque wrench in the rod itself.

If I get the Geissele, I'll end up divorced and bitching about dating life like Mr Fred.

Although, he did try to grab on my nipple the other day. He stopped when I yelled rape. Next time I'm going to soil myself to keep him away.... :D
