AR vice blocks

Id extend that to Mega/Hodge, ALG, Centurion, Noveske (SMOS), 2A, and SLR as well as a few others I’m likely forgetting. All extremely robust and well proven to be good systems.

Agreed. The 2 best designs are BCM and geissele

I think the newer version has flats milled in. Mine does.

That's good to know! I have the Geissele for 5.56 and tried to save a few $$ for 7.62 and got the Brownell. It didn't have flats and was more difficult to use than the Geissele.

UPDATE!!!

After using it four times, I sheared every lug off. Don't get one.

Did you contact Brownells? I’d be interested to see what they have to say about that. Potentially you got one with bad heat treat, inclusions in the steel, or something? I can’t immagine putting enough torque on a barrel nut or flash hider to break that thing unless there was a defect or something weird going on.

No, I didn't. Guess it wouldn't hurt to try.

Okay, my bad. It's not a Brownells brand, it's a cheap knock off through Amazon. I thought it was a Brownells brand, but it's not.

I only use the Reaction Rod to install/remove muzzle devices, I don't want the torque being applied to a barrel nut focused on the receiver slot and barrel alignment pin. A wrap around receiver block works well enough most of the time but if I end up needing a fair bit of torque to align a barrel nut I typically use the blocks of wood with the receiver turned sideways technique.

OP hasn't been back to post I wonder if he figured it out.

Me personally I use the vise block that wraps around the upper. That's a lot of rotational torque to just 2 pins on the other vise. Not saying people don't use them and they don't work. But my 2 cents, increase your holding surface area reduce your stress.

Op here...I bought the Magpul BevBlock

How do you like it?

If I had to pick one of your choices, I would pick #1.

I like these the best:

I have one of these reaction rods from Gissele - I rarely use it. Prefer the plastic block that surrounds the receiver. Just my 2 cents...
