Barrel Vice Blocks

[Gray05]

I need a good way to secure my upper to install my muzzle device. Other than the geissele reaction rod, what do y'all use?

My upper is a billet SI-D. I assume I shouldn't use an action/upper block since a crush washer apparently takes some torque.

[unforgiven]

I think someone here drilled a piece of wood to slightly smaller o.d.,split it and wraped leather around barrel.Then put in vice. <dontknow>

Vice blocks on the barrel itself , I use aluminum vice blocks ( made for barrels ) & leather , but wood should work , as long as it keeps the barrel from moving .You really do not want to strain the receiver or the barrel extension , in any way.

I use a Knight's Barrel Extension Wrench. Much cheaper than the Reaction Rod.

Does it only work on their guns?

Works on all .308 ARs. I've used it with my PWS MK216, LMT MWS, and Bubbasks' DPMS.

I've never had a problem just using standard vise blocks on any of mine. If nothing else, a crush washer will give you more room to work with, than what you have when timing brakes or comps.

I use an aluminum vee-block in the vise to hold the barrel.

 

Instead of crush washers, I made a bunch of aluminum timing washers (various thicknesses) and torque the muzzle device down. It doesn't budge and a PITA to remove. :D

I picked up an aluminum vise block at Brownells. http://www.brownells.com/gunsmith-tools-supplies/rifle-tools/barrel-tools/barrel-vise-jaws-sku795015100-12470-29522.aspx

I've got a blown bike tube to put between it and my barrel.

Thanks for the responses guys. A good thread for future reference.

That's pretty sharp. I don't have any machining abilities or tools. How did you make those?

I own a machine shop with CNC equipment. :D :D :D

 

These were actually done "by hand" manually on my CNC lathe with my scrap aluminum.

 

Here's other crap I made for my rifle(s):

I'm not busting your ass,     well ok I am.

 

If you have access to a lathe why not just face off a few thou from the brake and time it with no shims required?

Exactly.  That's what I do.

The timing washers can be bought online from various vendors :) Wash

I rather add than subtract. Helps the "resale value" of parts.  <lmao>

For a crush washer I took a regular crush washer, dremeled out the center some for more clearance then bent it a bit in the vice.  Then when I put the flash suppressor on and tighten down, I can control where it needs to be fairly well and the bend in the metal keeps a solid torque on everything so nothing loosens up.

 A crush washer is ment to crush to index the Muzzle device tightly to index it.

Homemade barrel vise. Bore a hole in a square aluminum bushing the size of the barrel and split it, put it in the vise, and crank down on the press to secure it. I'm torquing an action on in this picture, but it works for muzzle work too.
