Review: Muzzle Brake with install video (focus JP)

Which muzzle brake is the best? Flash Suppressor or Muzzle brake? These are common question floating around at the range and on the internet. Let me start with a quick explaining of the difference between a Flash suppressor/hider and a muzzle brake. Without getting into details a Flash suppressor/hider essentially reduces (not hides) the visible gases which exit the muzzle that give the explosive flash you see after you shoot. This is useful for night shooting so the shooter does not get blinded by the flash of light. A muzzle brake on the other hand is designed to help reduce recoil by the way the ports are designed to help counter the forces which would normally push the rifle back into the shooters shoulder. The designs of the ports also help in aiding to keep the muzzle down and reduce climb on rapid fire which is why a lot of 3-Gun shooters prefer a muzzle brake. Follow up shots with a muzzle brake is much faster which is what hunters & bench shooters prefer. In my opinion, most civilian shooters enjoy their rifles at the range and shoot during the day since most ranges close when it gets dark, so a muzzle brake makes the most sense, and this review is tailored for those people.

I had the opportunity to test out a few different muzzle brakes and I decided to do a review on the one which worked the best in my opinion. I choose the JP Standard-Profile Tactical Compensator (JPTRE-2S). The stainless steel brake comes in different sizes for different threaded barrels and also comes in a stainless and matte black finish. You also have a choice between a standard or large profile so they make a muzzle brake for almost any AR-15 (.223) and AR-10 (.308) out there. JP includes a crush washer or peel washer and a pair of ear plugs which was a surprise since most of the other manufacturers don’t even include a washer and have to be purchased separately. One of the key reasons I chose JP over the others was due to the fact it is approved for 3-Gun SOF/Tactical/USPSA competition. The rule changes forced JP to design such a muzzle brake to meet the new 1” by 3” size limitation. I chose the standard profile to keep the weight down and to my surprise it weighs less than 4oz, which is less than other models that appear to be smaller in size. I suspect the engineers at JP took their time on the design with the way the ports were machined to keep the weight down.

When installed and aligned correctly, JP has ports out to the sides at the 9 & 3 o’clock positions and ports right on top at 12 o’clock to keep the muzzle from rising and reducing felt recoil. There are no ports on the bottom and this is nice when shooting in the prone position to keep dust from flying up from the ground. Some of the muzzle brakes I tested had ports both on top and bottom. The only issue I had during the installation was the washer was just a hair (1-2mm) too thin in thickness. The top ports were not dead center at the 12 o’clock position after I torque it down, so I removed the washer and the results were slightly better but not dead on. This could be due to the way the muzzle was threaded because other muzzle brakes I tried had a similar problem where combinations of washers were required to get them to align perfectly. The washer included in this kit was a peel washer and if you heat it up you can peel off layers(.002 thick) to help aid in indexing. The washer in my kit did not look like normal peel washers I have used in the past but that could be due to the way it was machined and the first layer covered the laminated layers. In the end I added blue thread locker on the muzzle threads and torque the JP without the washer just enough so it was as close to the 12 o’clock position as possible without muscling it. If it come loose over time red thread locker or a trip to the local hardware store will suffice.

I will compare the JP to shooting a rifle with the A2 Flash hider (Bird cage) since it is the most common configuration on a rifle. I used PMC X-Tac 55grain ammo at an outdoor range. With JP, felt recoil was significantly reduced to the point follow up shots and sight picture acquisition on the scope was actually possible unlike the A2 which required a reset on all ten rounds. This was expected due to the design of this muzzle brake. Muzzle raise was also significantly reduced compared to the A2 during rapid fire shooting because of the top ports. The JP really shines for fast competition shooting where seconds matter which is no surprise it is endorsed by Bennie Cooley. If there is one downside with this muzzle brake and others I tested is the noise level was increased. This is a trade off shooters have to consider when installing a muzzle brake. The noise level being at an outdoor range was tolerable and depending on whom you talk will yield different answers in terms of how much louder it is than the A2. It’s almost one of those things you have to try it yourself to see if you like it. Unfortunately I didn’t have the equipment to measure the db level at the time so I can tell you based on my experience as the shooter it was increased slightly more but not enough to bother me. If I had to, I would compare it to the sound of shooting a 9mm & 45 ACP. Something else to point out is your neighbors at the range will certainly know you are in the lane next to them since the gasses expelled to the sides create a small wave of concussion. As the shooter I did not feel any of the gas pressure compared to other muzzle brakes which was a pleasant surprise.

It is clear JP took their time and designed a muzzle brake which works as advertised and I feel comfortable recommending this muzzle brake to anyone. The price is slightly more expensive than other muzzle brakes, however you can rest assured you are getting a quality product with JP which is competition legal and best of all it is made in the U.S.A.

Enjoy the Video
