The PVA "Mad Scientist" was named by a group of customers who were highly impressed with the performance, fit and finish and ease of use that this brake afforded them. The ports are optimized for precision rifles up to 300 Rem Ultra Mag to reduce recoil, aid in precision and shootability, ease of install and do it all without directing muzzle blast back onto the shooter, optics and neighboring folks on the line. Brake performance has been tested by an independent lab with a recoil sled to show in excess of 40% total reduction of recoil travel, matching or exceeding the performance of other 1" diameter brakes... all without the back-blast associated from angled-port designs.
The Mad 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 money on each subsequent barrel that they purchase.
The brake uses (2) 15/16" wrenches to snug into place and does not need any thread locking agents to maintain position firmly locked to the end of the barrel for thousands of rounds of use.
The Mad Scientist currently comes in 5/8-24 Class 3B threads and setup for bullets up to 30 caliber.
Here is one such customer post on an online group:
"...got to try the mad scientist brake ... from PVA. Words don't do this thing justice. I could spot my own shots at 100, 200, and 300 like I never pulled the trigger. I didn't know that was possible! Fantastic brake and I won't put anything else on my rifle, ever. All my friends shooting their AR15s want to see if you make one for that!"
