I used the search funtion and find lots of info on Surfire lights, but not really anything on the brake.

I asked in the Vias brake thread about how they compared but really didn't get anything.

SO, for those of you who have the SUREFIRE muzzle brake, what do you think? Surfire seems to make a good case for it, but alas, it's their product.

Re: Surefire muzzle brake, opinions please.

I am running sure fire breaks on my guns and i find it to be at the top of the list of good brakes.

By years end i will have the Surefire break on all my bolt guns so i can just rotate my surefire can from gun to gun!

You wont be sorry you went with it!

I did go with it for my Surgeon build.

A nice older lady called yesterday to say it's done and that I have a balance to pay.

I'm paying it, needless to say. But it's got THE surefire brake, so I"m very curious about it.

Not impressed with the two I have shot, but i guess it is the best you can get if you want to use a can.

I shot a brake that Scott McRee designed and was very impressed, but it was not designed for use with a can.

Gap did mine too. They have blueprints from SF. I had them put a 45 degree shoulder on mine and asked them to "sneak" it in a little closer. George was a great help.

Don't understand. What do you mean by sneak it in a little closer. Do you mean put the ports closer together to each other, or closer to the barrel, or something else?

Brownells have them in stock according to their site, but I've heard stories about them not keeping it updated. Could be just hearing bad info though, I've had nothing but good luck ordering stuff from them.

Barrel will need to be turned down to at least .775 for approx. 2.75" if this is going to be for .308. .338 the barrel can be a little bigger, for .223 a little smaller.

If you go to their website it will give the specs.

Yes,

I don't have one right now to look but nothing much bigger then a Remington varmint barrel at about .850 or there abouts for the .308

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: g3ninfinite</div><div class="ubbcode-body">ok thats the one i have. It looked different from LL's in that it not has a flat area in the center for use of a wrench. </div></div>

I think they are all like that now.

Yes I think they all have to flats at mid body now, Could be wrong but those are all I have seen as of late.

If you go to Surefire's website the model numbers will show the adapter like above when you order from Surefire or anyone the adapter comes with the flats at mid body.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: ukdave28</div><div class="ubbcode-body">What Thread size are the Surefire Brakes ? </div></div>

Depends on the caliber and weapon. The one for .308 is 5/8x24. They make one that is for M1A with a different thread as well as the one for the .223 and .338.

Re: Surefire muzzle brake, opinions please.

I was thinking about getting one of these... The thread size is the same as mine but my barrel diameter is too thick. I was just going to buy one to try but guess not.

If only we were able to use suppressors in CA

Re: Surefire muzzle brake, opinions please.

Anyone testify to the effectiveness of the surefire brake? I would like to put one on a 300 WM build and cant find anything on the surefire website saying what kind of reduction to expect. I have got to figure that if Surgeon is stocking them that they are a very good product.

Re: Surefire muzzle brake, opinions please.

Question about a Surefire MBB556K brake (for AR15). What torque wrench do you recommend for the install of this brake? I don't see any flats on this so was wondering what is the best way to go about it.

Re: Surefire muzzle brake, opinions please.

I love mine, zero recoil on the AR, and no muzzle rise on the EBR w/ soft push on rear recoil, rapid fire w/ reddot staying on target. I got my AR SFMB from a vendor, and 308MB directly from SF, SF folks are great & very professional, A+ customer services.

Ok, understand. So they refer to a torque wrench to install this. What type of torque wrench do you use?
