100 percent necessary

I used these as instructed on the muzzle brake installation video They worked flawlessly. I have to say the people at MCARBO are spot on when they post a video for a product that they manufacture. If you ever need help; they are the most politely enthusiastic people that you will ever deal with.


Did not work / poor design ...

The barrel Jaws Mcarbo sent me are NOT the same as the ones shown in the installation video. They are shorter and do NOT have the deep and shallow cut-outs that are needed to properly grip the barrel. I literally tightened the vice as tight as it would go (I am 6'1, 270 LBS.) and it still did not secure the barrel. I used masking tape and it still slipped and badly scratched / damaged my barrel. With all of that I still could not get the muzzle brake to line-up correctly. I have seen several complaints now very similar to mine so I have to wonder why Mcarbo continues to sell this misrepresented product to customers knowing that it doesn't work correctly and damages customer's guns?

Too small

These are about half the size of the step down set on the installation video. They didn't hold no matter how tight the vice was because they are so small. Scratched the crap out of the barrel. Tape didn't help either. I have bought almost everything they sell for my Sub 2000, this is the first problem I have had with them. Still a great company.

Not what shown in install

Very unhappy with barrel jaws I received they were not the one they used in the install video, they are so small I had a had time holding the barrel still.


Used correctly, they work.

Ok, so IF you use these right, they do work. Now, you get the jaws that are pictured. They are not the same as in the video, cost savings I guess. Put several wraps of tape around the barrel and you have to REALLY crank down tight, almost to the point you think you will break the barrel. The video is pretty much on point, other than you’ll receive smaller jaws. I’m glad I purchased them even IF it’s for a one use only time.
