"Rocket Scientist" Muzzle Brake


Product Description

The Patriot Valley Arms "Rocket Scientist" brake is the next step in precision rifle muzzle brakes. It is designed for larger magnum calibers burning at least 45 grains of powder and it excels with calibers burning 70 grains or more.  The ports are optimized for precision rifles such as the massive 300 Norma Magnum and 338 Lapua Magnum to reduce recoil, aid in precision and shootability, ease of install. All without directing muzzle blast back onto the shooter, optics and neighboring folks on the line.


See what we mean in this video showing a 300 Win Mag during a match.  The shooter is using the first production-intent prototype Rocket Scientist on his 300 Win Mag.  The stage consists of 3 plates that must be shot twice each in sequence, fastest time to hit all the plates wins.  Distances are approximately 600 yards.

The Rocket Scientist uses a threaded collar in order to index the muzzle brake without additional machining work required on each barrel. It is also not 1-time use like other machine-timed brakes but rather can be used barrel after barrel after barrel, saving shooters significant costs with each subsequent barrel that they purchase.

All of the Rocket Scientists come with Black Nitride treatment to increase surface hardness and impart the black finish on the surface.  The Mad Scientist currently comes in several offerings for caliber size and thread pattern.

  • 5/8-24 with 30 caliber aperture
  • 5/8-24 with 33 caliber aperture (custom request)
  • 3/4-24 with 30 caliber aperture
  • 3/4-24 with 33 caliber aperture

Patriot Valley Arms' "Rocket Scientist" muzzle brakes are designed with the discerning shooter and competitor in mind. Here we see the very first prototype on a 300 Win Mag being used to "clean" a stage at the 2017 ELR Precision Rifle match held in Wyoming. The stage consists of (3) targets at approximately 600 yards engaged Left to Right, then Right to Left. All performed for the fastest time. 7 shots, 6 hits all in appx 25 seconds. Notice the straight back recoil, no muzzle hop, and directed blast so that the shooter and those around are not concussed at each shot.
