![]() Here it is, ask and you shall receive! Close up photos of the actual Olympic Arms post ban muzzle brake. These brakes are standard features on the CAR-97 and PCR-7 Eliminator models, but are options on all other factory Oly weapons. What's the idea behind a muzzle brake? Well, to be honest it is two-fold. First off, it IS functional. It does serve a purpose on an AR-15 style firearm. The muzzle brake is designed to reduce felt recoil of the firearm, as well as reduce "muzzle jump" or "muzzle climb". Reducing felt recoil has its obvious advantages. We really do not need to go into a great deal of detail here on this particular subject. It is fairly self explanatory as to why you'd want to reduce the recoil of any firearm. But suffice it to say that the less the recoil, the more comfortable it is to shoot, and therefore, you are more likely to shoot more often. Additionally, the better the firearms feels to the shooter, the better they will be able to shoot the gun. The more consistent and accurate a shooter can perform, the more likely we are to make a lifelong shooting sports enthusiast! Muzzle jump is the result of (among other things) expanding gasses exiting the muzzle. Muzzle jump is best defined as the process in which the muzzle of the firearm rises in response to the firing of the weapon. The muzzle climbs upward, taking the shooter off target. The less muzzle jump, the faster the shooter has the ability to regain their sight picture, and get off a second or successive shot at the target. Sometimes speed is essential, especially in matters of self defense or law enforcement. By law of nature, expanding gasses at the muzzle are trying to equalize themselves as quickly as possible. To do this, the gas travels the path of least resistance. Or, in the case of a rifle barrel, basically straight out. This gas pressure however can be harnessed to the advantage of the shooter. This is where the muzzle brake comes in.
All Olympic Arms barrels for post ban firearms come equipped with what we call a muzzle "groove channel". This grove channel as seen here ![]()
To reduce both muzzle jump and felt recoil, the expanding gasses at the muzzle (as mentioned above) can be redirected. To do this, we use a muzzle brake. As seen below. ![]() The Olympic brake is designed with an expansion chamber. This is an internal area within the brake that allows the gasses to expand, and then redirect out of the designed ports. To create an expansion chamber, the inside of the brake is machined larger than the input and muzzle ports.

If you are unsure as to whether a brake is for you or not, my recommendation is to buy it with the gun (what else did you expect me to say, I AM after all a sales person!) But seriously, they do add value an attractiveness to your gun, and for all the more it cost, it is well worth it. Buy it, shoot it, see if you like it. If you don't, take it off and sell it, you will be able to get more than your money back for it. Hope this helps.
