can this be done? I don't have a vice at home, nor do I have an ATT to take my rifle to work. I have lots of many other tools, as I am a liscenced mechanic, and as such am reasonably familiar with working with them.

I don't want to put any idiot marks on my nice rifle, and I really don't want to tweak it as it shoots well.

Any ideas? anyone done this in the past?
 
Wrap the barrel with rope and secure it on a 2x4 or something that won't damage the barrel. Kind of like how a cloth filter wrench works.
 
Muzzle device general are not torqued on that tightly, I normally just hold the rifle between my legs and just use a wrench to take them off.
If the muzzle device is pinned, than you have to grind weld off.
 
Find an upper receiver vice block online pretty cheap and take the upper to work. That's the easiest and safest way to do it. As a mechanic, you know that having the right tools for the job makes life a lot easier!

I can be done like the others have mentioned, but a vice block is fairly inexpensive and guaranteed to work.
 
I actually broke an indexing pin on a barrel tightening a muzzle brake to only 30lb/ft of torque.

Wrap the barrel in a piece of wet leather and secure it in a vice.
The best tool for the job is actually the Geissele reaction rod which holds the barrel from the barrel extension.
This prevents any torque from being transfered to the upper.
It is currently on backorder at Arms East.
 
hey, thanx all!

yea, duhh, I forgot that I just need the upper... I can haz vice at work...derp...

I will try it just holding it really firmly. I figured it was gonna be on there really tight. Often I take things off at work that are supposed to be in the 100lbs/ft region that take near a thousand to take them off. IE: me literally jumping on a 2.5 foot bar several times. heat and crud=seized often times.

I will get a vice block too just because its a good idea. And I like tools :)

I've used the reaction rod to assemble a couple uppers and it is by far the best tool for the job. I would never use the vice blocks if I had the choice to use them or the reaction rod.
Order directly from Brownell's
 
I would prefer to use either the barrel extension wrench, or simply hold the barrel itself in a vise with blocks in a vise. The latter is easy and fast. No reason to apply any torque to the upper receiver.

Yep, best receiver tool by far. Simple to use, and you do not stress the aluminum when applying torque.

Pinned or if he's installing a new device that uses a crush washer.....
 
I wish AR's could swap muzzle devices like on an AK or VZ rifle. Those Eastern Europeans did a good job on a user friendly system.
 
i don't see why you'd need to involve your favorite illegal or immoral activity while you remove your muzzle devices...but hey whatever floats your boat.
