A Little History
Muzzle brakes have quite an interesting history. They were originally designed for artillery pieces and anti-tank guns. The recoil from artillery guns can create serious issues as you can probably imagine. Hence, manufacturers developed muzzle brakes to help keep recoil down. This made artillery and anti-tank guns easier to shoot, and create less hazard for the soldiers operating the guns in the immediate vicinity. It also enabled the guns to increase their rate of fire on the battlefield.
Most muzzle brakes can be threaded on end of the barrel. While others can be twisted, clamped, or pinned on as well. Most muzzle brakes also use a venting system, where integrated ports or vents are drilled into the brakes to enable the gas to escape from the muzzle.
What Is A Muzzle Brake and Why Do You Need One?
You may want to consider getting a muzzle brake if you want to minimize recoil and muzzle flip. You can easily attach the muzzle brake at the end of your rifle to redirect propellant gases away form the barrel and rifle with each shot. This serves the dual purpose of reducing recoil and muzzle rise at the same time, making it easier for you to fire follow-up shots. As a result, it helps increase your accuracy and comfort level.
You can reduce muzzle brake from ten to fifty percent. How far the barrel profile raisesover your stock also plays a big role in how much recoil can be reduced. However, one of the downsides of muzzle brakes is that they can increase the noise of your rifle or carbine when firing. So this is a tradeoff you need to consider. However, the increase in noise can vary dramatically depending on the muzzle brake that you use as well.
Why Go With The .300 Blackout?
There are many calibers available for the AR-15, and many gun owners easily confuse them. For example, several people confuse the .300 Blackout with the 6.8 SPC. Both the .300 Blackout and the 6.8 SPC share the distinction of military use as a potential improvement over the standard 5.56 and .223 Remington rounds.
The 6.8 was intended to be a better performing round at longer ranges while functioning out of the standard 16-inch AR-15 barrel. The .300 Blackout, on the other hand, was designed with the .300 Whisper round in mind. Specifically, manufacturers created the .300 Blackout for the special operations units in the United States military. The idea was for AR-15 carbines to chamber the .300 Blackout that could potentially replace the 9mm submachine guns in use. An example is the Heckler & Koch MP5. Numerous MP5 submachine guns were several decades old when the .300 Blackout was developed.
With the .300 Blackout, it was envisioned that special operations soldiers can equip themselves with a 6 to 9-inch barrel with a standard M4 receiver, bolt, and magazines, similar to the standard issue 5.56 caliber guns. They just need to replace the barrels, at which point, soldiers would have a weapon very similar in size to a 9mm submachine gun, with greatly enhanced stopping power.
You can also assign the .300 Blackout to work with a suppressor. Hence, it can greatly reduce noise out of a suppressor than a 5.56 rounds. Both the recoil and noise from the .300 Blackout, out of the right rifle, can become as minimal as a .22 LR.
