Vism buffer tube/lower receiver block colt odg

[Derbster]

Well I decided to finally put on a colt odg 4 pos. tube on my centurion lower that I've had for a little bit along with a magpul endplate and a fcd castle nut. I also just got this Vism block to help to do it. I have another lower I want to swap tubes on and so does my neighbor so I figure why not get a tool to help with that job. It seemed to work great.
I was conflicted on getting this or the geissele or some of the others out there but for like $32 I can't go wrong. I used a generic ar15 armorer's wrench. It worked but didn't care for it. Is there any castle nut wrenches or tools you guys like?

You know what I use? I use a brass punch and a little ball peen hammer. I use the notches on the castle nut with the brass punch and I tap it in to position give it one good whack to tighten it down and then I stake it in place. No fancy castle nut tool. Just a good brass punch and a 8 oz ball peen hammer.


I've been doing that for years I've never had a problem with any of the castle nuts that I've installed that way with either my rifles or anybody else's that I've built

Yeah. I thought it was a little over board but I like tools and that one was cheap. Being a mechanic I get into these things. Ha.

I've used several different wrenches and the brass punch method.
Bought the Magpul armorer's wrench 5/6 yrs ago(?) Wish I'd bought it sooner .

I get that. I'm a tool geek too. But I also like the simple solutions LOL

Magpul Armorer's Wrench. Engages both stock and pin-style barrel nuts. Fits standard sized flash hiders. Installs and removes rifle receiver extensions and carbine castle nuts, and has extended teeth for use with ASAP® plates.

I like that jig. I have trouble with some buffer tubes having slop and not torqueing up square and being canted one way or the other.
