Overall Customer Rating of 18 Reviews:

I dont recommend

The barrel jaws did not secure the barrel from spinning, no matter how tight I tightened using a vise. I scratch the crap out of my barrel instead. I watch the tutorial on YouTube and did the same exact steps except the barrel jaws they had were different from the one they sent me. I ended up taking it to a gunsmith and they installed it in for me with their tools. I would still buy stuff from Mcarbo even though this product didn't work.

I added a star, to not bring their average down, but I forgot something.
The customer service rep said that aluminum jaws cannot scratch steel. But it sure as hell stripped off the blue. I’d love to review the muzzle brake, but I can’t get it on without spending more money. The customer service rep suggested I should rerun my vice to a place with a sign that says “no returns” I wanted to buy mor MCARBO products, but I will not.
Seriously, your genius engineers decided to design a product with four points of contact , rather than one that is round with 360 degrees of contact?

After talking to customer service.

I spoke to customer service about my problem with this product. I will say they are responsive, however not helpful.
The response was; yeah, we know that the barrel jaws weren’t the ones shown in the video, that said you can use a cheap vice (I bought the same vice that was in the video), but we decided to send a less expensive set of jaws. We didn’t want to charge that much for a tool. So we scaled it back. Then she told me that I would have to use a much more expensive vice to make the product that they sent me work. Double the price of the more expensive jaws that were in the video, would have saved me $30-$50 on the price of the vice I needs to buy. Net! Sell the right tool!


Worst product ever

No matter how hard I wrenched down on my vice, the barrel twisted around freely within the jaws. Scratched the hell out of my barrel. Never got a 360 degree turn. Maybe about 90 degrees before the barrel slipped within the jaws. I even tightened my vice with a cheater bar.

These are half the size shown in the video. If you are selling a product make sure you sell what you advertise. Not happy with them.
