Muzzle break

Not much to say. It’s Great!!

Was unsure how much difference it would make since theres not much recoil to start with. But really makes follow up shots easier. Would recommend this to any one that has a PC carbine.


Great muzzle brake with an easy install and great quality!

Easy Install - Works Great

The MCARBO muzzle brake is worth every penny! It flat-out works great and installation is the easiest I've ever experienced. GET THE ROCK SET - it's great.
Let's face it, recoil on the 9mm ain't bad (compared other stuff I shoot), so I was after the muzzle control. It improves rapid fire control & also makes the gun look badass.
The jam nut design is awesome. I'm no gunsmith & haven't got a barrel vice required for installing & timing muzzle devices.
Chris, if you're listening, I can tell you that your jam nut pocketing into the muzzle brake is a genius design. Please consider developing muzzle brakes for other calibers & purposes using this great design. Just yesterday I was wishing you had a .223 like this one ... I had to take the rifle & brake to a gunsmith to have it timed. Once again, I see a market for what I just mentioned.

Well worth the cost

When you hold this thing in your hand, you will understand why it costs what it does. It's very well made, much nicer than MB's I've purchased from big manufacturers for even more money.

It makes a real difference for the shooting experience, as well. The overall effect makes it easier to make quick follow up shots accurately.

As many others have written: Just buy it, it's a great upgrade.
