Matador Arms "The Regulator"

  Matador Arms has been making various aftermarket firearm parts since 2015. They have made products from an SKS chassis to a folding stock adapter. In the range of accessories they manufacture is “The Regulator.” The Regulator is a fully adjustable muzzle brake available in 4 different calibers. I installed the .223/5.56 one on a 16” AR-15.

  The first noticeable attribute of The Regulator is its length. It is notably longer than what you may be used to. It measures in at 3.6” long. This is partly due to its adjustability. One probably won’t be able to use this in 3 gun competition, due to a 3” muzzle device rule, but that wasn’t a concern to me. The outside diameter comes in just over an inch at 1.08”. This is also partially due to the adjustability of the Regulator.

  The Regulator is essentially a 3 port compensator. Meaning it has 3 large ports on each side, somewhat facing rearward, and 3 holes in the top. The 3 top holes force the muzzle down upon firing. While the 3 side ports help to pull the rifle forward to aid in felt recoil. Of course, the Regulator has the advantage of being adjustable. 

  Yes, I did mention adjustability, and this is where The Regulator shines. With the Regulator, you can adjust the compensation from all the way off (closed) to fully on (open). In between off and on, are roughly 60 different adjustment points. Best of all, no tools are needed to adjust it. Just turn the adjuster nut at the front of the Regulator. Every 1 of the 60 “clicks” is an adjustment toward closed or open. If you are at an indoor range, for instance, you might want to close the Regulator so you don’t blast the shooters next to you. However, if you want the full compensation effect, open the comp all the way up. If you want to tune your specific ammunition to the firearm, start with the Regulator fully open or closed, and start adjusting until you get the desired amount of compensation. I found that with my rifle there was too much compensation when the Regulator was opened up the whole way. I ended up adjusting it 9 clicks away from full open. This gave me zero muzzle rise and a decent reduction in felt recoil. When I used the Regulator fully closed off, it was exactly like shooting a rifle without a muzzle attachment of any sort.

  Installation is pretty straight forward. In order to install the Regulator, one must first disassemble the muzzle brake. To do this, unscrew the adjuster knob until it comes off. There may be a little spring pressure on the knob, so be careful. Then slide the outer portion of the Regulator off, and the short spring, leaving behind the inner compensator. Install the inner compensator with the 3 holes facing up. Matador Arms includes a crush washer and shims for the install. The inner comp has wrench flats to aid in properly torquing down the compensator. Then reinstall the outer components and hit the range. The inner compensator would also work as a stand alone brake, but I don’t know why one would want to do this. 

  I tested the Regulator quit a bit. I even measured the muzzle rise, shot times, etcetera with my Mantis X10. I really do like shooting with the Regulator adjusted to my rifle. It definitely reduces muzzle rise to nothing, or even negative muzzle rise if adjusted all the way open. I was able to get faster, accurately placed, follow up shots. From 0.3’s to 0.15-0.20 second split times. I did notice that if adjusting the Regulator between strings of fire, it is hot, so wear a glove, or use some sort of thick cloth. Since the Regulator is adjustable, it will work well on shorter barrels. Shorter barrels usually produce more escaping gases, causing standard muzzle brakes to over compensate. With the Regulator, just adjust the gas output down and this problem is solved. When shooting the Regulator closed, I could definitely notice that it was much quieter to my ear. When fully open, it is loud to the shooter and those near the shooter, but that is just the drawbacks to any compensator. Oh, and sometimes with the Regulator closed, it produces a very large muzzle flash, quite exciting for someone if they aren’t expecting it.

  I can say that I am very impressed with the Regulator. Matador Arms did a great job in designing adjustability into a good 3 chamber compensator. It does everything they told me it would do. Go check out Matador Arms, if nothing else, Canadian gun companies could probably use some of our help right now.
