APA is proud to introduce the Gen 4 Little Bastard. The Gen 4 is a culmination of engineering improvements as well as a little bit of what you asked, they listened. 

The 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 lower concussion maximum recoil reduction product.

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, they 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 they really dug into, and have found this to simply be not true. Borrowing from decades of research in the golf industry with their “sound is feel” philosophy, APA 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. APA 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.
