Anyone tried to take one of these brakes off? Thinking about taking it off and gunsmithing it on a new barrel, whatever that may require. . .

I like the ON/OFF feature,

It looked closely, and it appears that they counterbore the muzzle after drilling the holes in it, then thread it, slide the ON?OFF sleeve on with some sort of detent system, then thread a muzzle cap on thatholds the slider in place. . . .

Anyone try messing with these,

Inquiring minds want to know!

I'll probably end up buying a Shrewd, because I have shot Vias and a shrewd, both on RUM's and the Shrewd seemed to be easier on the shoulder by a good margin. . .

...............Sharpshooter can tell you exactly how to remove it, maybe he will chime in.

It is a complete assembly that is threaded on the barrel not built like you are describing.

From memory (best to wait to hear from SSS before you try) pretty sure it has standard threads, you open it and insert a steel rod through the holes then turn it off as an assembly. Some kroil on the junction where it hits the barrel overnight would be a good idea to help loosen it up.

I've always used a bandsaw.... ;D
I think Too many is correct, although I've never un-screwed one.

Well Fred. . .. .
After half a can of Kroil, 12 hours of waiting, and 3 bent punches later. . . . that SOB is still on there. . . .

Does anyone have one they cut off that I can get a hold of and try to get it apart, so I don't have to destroy a good Factory barrel tryin to get this apart. . ..
:'( ???
If all else fails, I will call the mother ship in Massachusetts to see if they can help me, after the holidays that is. .. . .

If Savage uses Rocksett like the brake and gas block on my DPMS LR308B, then heating it up makes it fairly easy to remove. I used a propane single burner camp stove because I don't have a torch. Heating it sufficiently makes the Rocksett soft.

hmm, I'm sticking with my original inference on this one, that thing is machined on the bbl itself, . . . . .

Im callin Mass. ASAP

I'll keep y'all posted on my progress

I'm certain its threaded on and probably with Hi-temp rocksett. You'll have to get it real hot before it will unthread-not heat gun hot but torch hot.

I have removed three. no thread lock. just the same gal that put on the barrel nut and bolt screw. put 3 or 4 nails through it and clamp it in something. turn the gun and the brake screwed off. the thread is an odd 9/16 that nothing common will match, so it the end you wind up cutting it to put on something else.

THANK YOU avenger!

I will go give that a shot, I was planning on using it on a 300 RUM build with a shilen barrel, so I can thread the muzzle to match the brake, I just don't think I will want the brake 'on' when hunting with it . .. . .

I'll let ya'll know!

SUCCSESS IS MINE!!

BTW: Finishing nails are too soft for this project, and the muzzle is threaded 9/16" X 28 TPI, A Gentry #2 among others will screw right on these bbls

You'd be surprized how much recoil reduction that factory brake is good for...
It's only about 20%. If you think the Shrewd brake is better than the Vais, bring it over and we can test it on my recoil fixture.

Yep, that dried white stuff on the threads is Rocksett. Heat it up red hot and it comes off much easier.

Fred,
You want me to buy a shrewd and a Vias, you think I'm made of money or what, not to mention I would have to thread the barrel 2-3 times

Well now that I fought to get it off there, I'll probably still buy a Shrewd for my 300, or perhaps . . .. .

What do ya'll think?

This thread interested me as I received a new 10FLCP-K from my former unit and Savage as a retirement gift. Mine has a muzzle brake but it's the newer one (not the adjustable one as shown in the instruction booklet). It is simply "slotted" for a wrench on the threaded end.

Don't buy anything till I talk to you at the show...
