Ultradyne USA, the guys who made what are possibly the best iron sights on the market, also build what are arguably the best muzzle devices. The combination makes sense, as it allows them to play to their strengths by selling compensator-sight combos.

The APOLLO MAX Muzzle Brake (below) is notable: After rigorously testing the brake with a load cell device that measures up to 50,000 data points within a recoil event, Ultradyne learned that the Apollo Max can provide as much as 25% more recoil reduction compared to other top brakes on the market. Since muzzle brakes typically reduce recoil about 50%, that makes for a serious improvement in accuracy using a product that’s completely competition-legal.

Apollo Max / C4 Dynamount Sight Combo

Apollo Max is available in 5.56, .308, and 6.5 Creedmoor variants. This is their flagship muzzle brake, and it provides unparalleled performance without compromise. Accordingly, since its sole priority is recoil reduction, it is loud. So, Ultradyne has a full line of brakes to cater to any shooter, which we show below. First, see the differences represented visually here:

ATHENA, also available for 5.56 or .308, is significantly less loud. Its vents gases forward while still managing muzzle rise excellently for about half the price of Apollo Max.


When developing MERCURY (shown below as a combo), Ultradyne engineers had the .223/5.56 caliber specifically in mind, and they fine-tuned this design accordingly to create a brake that has a nice combination of performance and shooting comfort. It features progressive 90-degree side ports that evenly spread out recoil for an extremely smooth, comfortable shot. Mercury expels gases to the side, which helps reduce noise compared to the Apollo Max. The ports that reduce muzzle rise are spot on, so the shooter experiences very little rise during the shot. This can dramatically increase the speed and accuracy of the second shot.

Mercury / C4 Dynamount Sight Combo

Finally, PEGASUS is Ultradyne’s tanker-style .308 and 6.5 Creedmoor compensator. Besides looking badass on your rifle, it delivers best-in-class performance for those calibers. Similar to the Mercury, the progressive 90-degree ports set this brake apart.


Why would I buy a muzzle brake in the first place?

If you’re new to this accessory, the idea behind it is simple. Combustion releases gases when the gun is fired. The reactive force of those gases exiting the barrel results in recoil, and because of the position of the shooter behind the gun, that recoil causes it to move not only back but also up (this is called muzzle rise).

However, there’s no law on the books that says those combustion gases must all be directed forward. If you redirect them at a backward angle, you’ll almost negate the recoil. Distributing the gases at a perpendicular angle to the barrel will compensate for the force of the explosion, reducing it significantly. That’s what a muzzle brake or compensator is for.

The angle is important. If gases are directed straight back, the result is an extremely loud shot and a face full of smoke. This is why muzzle brakes designed for rifles are carefully engineered to sit in a sweet spot, lessening recoil and therefore improving accuracy during follow-up shots. However, one “sweet spot” doesn’t fit all, as different shooters prioritize noise and recoil reduction differently. So, to ensure a great match for many different shooters, Ultradyne offers the Athena, a linear brake oriented around comfort, the Apollo Max, a no-compromise performance brake, and everything in between.

  1. “Why would I buy a muzzle brake in the first place?”

    Why, to anger and piss off the guy next to you at the range.

    If you need a brake, get a smaller caliber

    • Exactly why I bought a blast forwarding device from, I think, if I remember correctly, Indian Creek design.

    • Ignorant much? Why not make what you like to shoot softer? No one ‘needs’ a brake. But they make shooting more enjoyable. Fudd

      • More enjoyable? Not for anyone who is near that thing. Brakes are obnoxious. if you can’t handle the recoil get a smaller caliber………

      • I would agree with you particularly if someone is practicing with their hunting rifle for hunting season, or actually hunting.

        If someone has a rifle setup that has a significant blast, hopefully they can find a range that uses shooting booths.

        Let’s not forget the very important fact that muzzle brakes aid rapid follow up shots for the military, LE, and competition shooters.

    • Haha, might as well since one can’t have flash suppressors.
      Muzzle brakes are awesome. Don’t like the noise at the range? That’s what ear protections are for, double up.
      That’s like saying, “Don’t shoot your .338 LM because it’s too loud for others.”

  2. ““Don’t shoot your .338 LM because it’s too loud for others.” no don’t shoot it with a muzzle brake, cause its obnoxiously loud and you are an a$$hole for inflicting the noise on others.

    Get a suppressor or a caliber you can handle.

    • If you can’t handle the noise, get out of the shooting range.
      Suppressors are illegal in Illinois.

  3. wow. amazing comments here, I shoot a 300 Ultra for large Mule deer and Elk. I shot my hunting rifle about 4 times without a brake, and it knocked my scope back in its rings. They were torqued to spec and were decent rings that were mated to the scope. It’s science you can’t get around the recoil of a 225 grain bullet cranking out at 3200fps. Some guns NEED a break. For those saying shoot a smaller caliber, explain .223’s with some breaks for competition and sport. For those upset at firing lines… It’s a gun range and your whining about it being loud??? amazing.

  4. its funny the Boomer here complaining about being loud well dee dee dee its a high caliber rifle so yes and when you want to make that fast follow up shot and want it on target use a break secondly I shoot long range outdoors where no one is right next to me our positions are five to seven feet apart leaving plenty of room for cry babies to complain about Noise.
