Muzzle Brake

Help Support Ruger Forum:
A muzzle brake has 2 effects - one is desireable, the other is not.
First, the primary purpose is to reduce recoil.... if you feel the need to reduce the recoil of a 9mm Carbine, then go for it.
The unintended side effect of a muzzle brake is increased noise..... somewhat louder, but not too bad, to the shooter, but really annoying to anyone alongside the shooter.
On a 9mm, probably not a big deal.... but when somebody uncorks a .300 mag with a brake, the blast can be felt 10 feet away.

I'm a big fan of linear compensators, even on my 9mm carbines. They do a good job of redirecting the muzzle blast down range away from both shooter and spectators. They also have a positive effect on muzzle rise.
Kaw Valley offers a number of Linear Comps in various thread sizes and calibers. Joe Bob Outfitters carries a most of them.

Be sure that whatever muzzle accessory you purchase is made for a 9 mm bore. The threads on the PC Carbine are 1/2"-28 and this is the standard for most .223 Rem./5.56 NATO barrels. You don't want to put a .22 caliber accessory on a 9 mm barrel!

Every muzzle brake I'm familiar with directs the blast off to each side - that's how they reduce recoil. Directing it downrange would be the same as no muzzle brake at all.
Recoil was explained about 500 years ago by an Englishman named Isaac Newton.... "for every action, there is an equal but opposite reaction". The recoil of a rifle is the result of the bullet AND the gas exiting the muzzle. Take, for instance, a .223 with a 50 grain bullet and a 26 grain powder charge; the gas generated constitutes 1/3 of the total mass exiting the muzzle, or a .30-06 with a 165 grain bullet and a 57 grain powder charge, where the gas constitutes 1/4 of the total mass. If the bullet and the gas are all going straight away from the shooter, the recoil is straight back. If you can vent a portion of that gas off to each side, they will counteract each other, and also reduce the amount going downrange, thereby reducing the recoil. In some types of brake, they also vent gas upwards to reduce muzzle rise.
The 9mm Ruger PC Carbine's thread is 1/2 x 28. The device I am looking at is:
Kaw Valley Precision 9MM Linear Compensators in a Black Oxide finish.
Linear Comp Specs:
Thread: 1/2" x 28
OAL: 2 1/8"
OD: .95 Inches
Caliber: 9mm Caliber Firearms KelTec Sub2000 / AR9
Weight: 2.9oz
Heat Treatment: Ferritic Nitrocarburization
Surface Hardness: Approximately 60 Rockwell
Surface Finish: Black Oxide
Unless I am mistaken this seems to be compatible with the Ruger.
To install, is it simply a matter of screwing the device onto the threaded barrel of the carbine?

If you look at the specs, they only claim it reduces noise to the shooter.... nothing about recoil reduction or muzzle rise reduction. Since all the vents face forward, it makes sense. Also note that they don't call it a "muzzle brake", but rather a "linear compensator".

I don't know whether a muzzle brake would be advantageous or not -- but I definitely appreciate your referring to the device correctly as a muzzle BRAKE! I get seriously tired of seeing all the gun-forum discussion of "muzzle breaks".
Here is an inexpensive one from MidwayUSA

That's a flash hider, not a brake. It will have no influence on recoil or noise.Rumrunner said:
After reading all the responses,doing additional searches and viewing videos, I purchased a SuperComp 17-4 SS Black Nitride Muzzle Brake.
Hopefully, it will prove to be as excellent as it appears to be in the literature.
My thank again for your suggestions and most informative information.
