Looks like APA has come out with their latest generation of brakes. Curious to see how they perform in comparison to the ACE and new Hawkins updraft brakes.

OUR SOFTEST RECOILING AND FLATTEST SHOOTING BRAKE EVER

APA is proud to introduce the Gen 4 Fat Bastard. The Gen 4 is a culmination of engineering improvements as well as a little bit of what you asked, we listened. As the long-range precision rifle community grows, the shooter has gotten more refined and discriminating. This has presented us here at APA with new challenges to improve.

Our goal for the last year in developing the 4th generation was two-fold; one to make the flattest shooting brake on the market and two, to create a low concussion maximum recoil reduction product. We are happy to announce that we did it!

The new calibrated U.R.P tunable top ports have been designed for maximum adjustment making the Gen 4 line of brakes the flattest shooting brakes available hands down. By testing port size, location, and how the gas feeds into them, we have been able to make these tunable top ports capable of generating zero vertical movement.

The new fine-tuned Bastard port has been engineered to decrease concussion while retaining maximum recoil reduction. In the muzzle brake community, there is an unwritten law that says “more concussion, more recoil reduction” and vice versa. This is something we really dug into, and we have found this to simply be not true. Borrowing from decades of research in the golf industry with their “sound is feel” philosophy, we wanted to figure out why a technically more effective and superior muzzle brakes would often anecdotally “feel” harsher even though the gun moved less and moved slower. Well, we had a eureka moment with how the sound or tone works in conjunction with the physical recoil. The new fine-tuned Bastard port and internal manifold produce a softer and sonically smoother recoil impulse by shaping the sound, into a lower frequency. The perception to the shooter is a much softer shooting rifle. This brake is easier on the ears and easier to stay in target, period.

Although the DNA remains the same, the new Generation 4 Fat Bastard Self-Timing Muzzle Brake is a completely new beast. It is flatter shooting, softer recoiling, more tunable, and easier to use than ever.

1.1" in Diameter, 3.3" In Length, and Weighs 6.4 oz

Made for barrel diameters of .8 to 1.1 inch.

The Gen 4 Fat Bastard can handle magnum cartridges.


Available in 6mm, 6.5mm & .308 (7mm) with more calibers to come.



• New optimally tuned top ports for maximum efficacy and tunability.

• New port design and internal manifold that is more efficient, and softer sounding.

• Caliber and level line machined on brake face.

• No Thread-tite necessary in top ports.

• Completely machined in our facility in Jefferson GA

Anyone got one of these yet? I went ahead and ordered one. Super curious the difference between it and the gen 3 in actuality. Also interested in the comparison with the ACE.

Tested my Gen 4 Fat Bastard today with 6.5CM in a 14# rifle. I do not have experience with the previous gen but I do know what brake concussion feels like.
I took off all the set screws to test and it did a good job with controlling muzzle rise and keeping the target in the FOV. Recovery is fast as expected.
Now to concussion or lack thereof.. As the shooter I could still feel the thump but it was mild and tolerable. Standing off to the side about 7-8 feel away at 90 degrees and then in line with the angle of the ports the thump was noticeable but also mild to me. It’s going to vary person to person but I didn’t think it was obnoxious. I only wore ear muffs. I’ve been around much worse. Could I shoot this brake all day? Probably. Let me reiterate, yes I know people have different tolerances to concussion and noise.

Well you can’t say I don’t have other brakes to compare it to. 🤣

Ok, how does it compare to other brakes in terms of recoil reduction though?
Of the ones I have, it’s not the best performing one. I know the Chad costs way more but I feel it does a better job all around. I mean it’s going to be hard to convince someone otherwise until they shoot it themselves or see numbers on a recoil sled with sensors. The Gen 4 does do a good job with muzzle rise but I feel it could be better impulse wise. This is all based on free recoiling with little shoulder input.

I like brakes more than the next guy and love playing with the latest and greatest ones, but I think we're so far into the realm of diminishing returns with high end brakes that any gains at this point will be in tiny nearly imperceptible increments.
