You could probably do it with a couple calculations, like going from force to acceleration by dividing out the mass of the rifle … but I’ll leave that up to you to do if you’re interested in getting to that. Your own words lead me to recommend your next science project – comparison of suppressors. Keep up the great work and I am sorry you have to deal with the manufacturers phone calls (I bet their returning the calls now) disputing your science after you publish each blog. Thanks, again! That load is also roughly representative of the popular 6mm Creedmoor or 6×47 Lapua cartridges. Some are only available in 30 caliber. I actually wasn’t able to test it on a few rifles, because the Badger FTE design requires the barrel to be contoured to exactly 0.800” or 0.875”. Looking forward to the 30 cal results. Lets take out 6mm bullet, which has a frontal surface area of π(6/2)^2=28.27mm^2. Smith Enterprise - AR .308 Muzzle Brake .905 30 Caliber; Timber Creek .308 Heart Breaker Muzzle Brake; Review of the Best AR-10 Muzzle Brakes. It seems pretty precise and objective. They make my ideas 10x better. Benny Hill Rolling Thunder $82.99. That means it wasn’t what I expected, I had some bad assumptions … And I actually learned something I didn’t know. Someone else asked a similar question, and I published a chart in response to that which shows how the 6XC and 6.5 Creedmoor compare with no muzzle brakes. I study and enjoy your every post. In order for it to make a 10% difference, the area would have to start out at 53.0mm^2, or an 8.21mm (diameter) hole. The recoil data was collected using high-speed, high-resolution force sensors. Cerakote ODG AR-10 / 308 Shark Muzzle Brake + FREE Crush WasherCNC Machined High Quality Steel Heat Treated Works On 308 Model 10, LR308, 7.62x39 Uppers, 300 AAC, 6.5 SPC, and most other 30 … This isn’t a suppressor field test, but I just wanted to include one on this first set of results for comparison. But, that doesn’t mean we can’t gain insight into it if we take an “all things being equal” approach. Without further ado, here is the data for the recoil reduction on the 6mm rifle for each muzzle brake: Any surprises? For average shooters picture ” talk ” more than name. Many thanks. If you want to stretch out and get longer range, I’d highly recommend the 7mm Rem Mag (or similar 7mm magnum). Quick view. One might argue ..(or future test ,-) for that matter).. the relative merits in real world, mag-dump etc, multi-shot exercises of removing as much recoil (reward push) as possible – versus – concentrating more on neutralizing muzzle climb .. for an analogue of experienced shooters rather than single shots in a sled, – getting long-winded here, the current linear test rig could be altered into a fulcrum .. still measuring rear push, but also able to measure muzzle climb (amplitude, total force, distance) in single and/or continuous fire, I’d think one might need a replacement hand grip to use as the mounting point .. since a bench-rest sled format would tend to automatically curb the rotation – (and a trigger operating device so the rate of fire could be consistent for all units) but it’s not my meaning to visit those concepts so much as to say that the .223 and the .308 versions are more different (regarding the type of test that you have presently) than they’d seem to be on first glance and I hope to see the bigger brother included, even if the results regarding rearwards push turn out to be similar.. Hey, Westin. Out of Stock!

Another thing you may notice is the suppressor is more effective at reducing the peak force of the recoil (31% reduction) than reducing overall momentum (24% reduction). This brake is very effective at mitigating recoil. Keep up the great work! I’m just curious as to the difference in the actual recoil between the two calibers running your loads (with and without brakes). AR .308 Cal Slip Over Barrel Shroud With Multi Port Muzzle Brake (Flat Dark Earth) 1326-MB-P-308 … I’m just trying to figure this out like everyone else! You can see the suppressor isn’t as effective at reducing recoil as many of the muzzle brakes, finishing in the bottom half of the pack. Thunder Tech On the other hand, there isn’t a practical limit to the amount of gas a muzzle brake can redirect, and it can redirect that gas in a direction that allows it to do more work in our favor. Those external flats are completely nonexistent on the .223 version, so its middleoftheroad placement wasn’t surprising to me. Beyond that, there was a big group of muzzle brakes in 26-36% range of recoil reduction. He may get to that before I can, but I will publish it at some point. Neither the JBM calculations nor my tests should be taken as gospel for what the perceived recoil would be. Patriot Ordnance Factory, 308 Triple Port Muzzle Brake, 5/8 X 24 Rh, Black Finish 309POF USA has positioned itself through superior engineering and design in making the AR platform the absolute best … The big question comes down to what measurement most closely correlates to perceived recoil from the shooter’s perspective. Another thing to keep in mind is that most recoil calculations are made for free recoil (rifle is allowed to travel backwards without obstruction). Lantac Dragon Muzzle Brake 7.62/.308 w/ Dead Air KEYMO Suppressor Mount . © Copyright 2021 PrecisionRifleBlog.com, All Rights Reserved. I look forward to each post as I learn more each time. JMAC Customs RRD-2C 30S KeyMount (KeyMicro) - 5/8x24 . I’m curious to see how well it lines up with your empirical results. I’m not sure. Force is a vector, so angles have a big impact. I’ve never seen anything like it being done either, and that is always fun to do something original. Subtracting our bullet from the bore we get our “holes” are 4.91, and 10.21 mm^2 respectively. I’ve a 30BAS, 30CB9 and a Ultra-9 in NFA holding. Add to cart. As I’ve said in the posts, I was surprised by a lot of the results. On the 6.5, I tested all muzzle brakes except the ones that I only had in 6mm … and the Badger (again, it wouldn’t fit). Very informative!

Cal – another incredible write-up!!! Cal, Cal is a life-long learner, and loves to help others get into this sport he's so passionate about. To be clear, I tried the 6mm, 6.5mm, and 30 caliber brakes all on the 6XC, and in all 4 muzzle brake designs, there was only a difference of 1-3% in recoil reduction in terms of both overall momentum and peak force. This brake is designed to be field serviceable/replaceable, which means it can’t use a shim kit or loctite to time and retain the brake. Lund/ SJC Titan The Lantac wasn’t included in these tests. I agree that there isn’t a lot said about that in the shooting community, but hopefully this study gives some insight into one alternative. I’ve got a 308 bolt action rifle with a muzzle brake and one that doesn’t have any threading at the end… when shooting 200+ yards (I don’t really hunt, just use them for target practice) with the same scope, the one with the brake is much more accurate. One the 6XC, I tested all of the muzzle brakes except the Badger (it wouldn’t fit because of it’s barrel clamp mount). Did any of the brakes significantly impact muzzle velocity? I tested the effectiveness of having a caliber-specific brake on 4 very different muzzle brake designs that I had in all calibers: the. Within a millisecond, the.308 muzzle brake diverts the gasses horizontally. Forgive me if this was addressed earlier and I missed it, but I know many people and myself that have been wondering why you did not include several other popular brakes on the market today? Great question. Your research has really been helpfull to me as a newbie to the precision rifle world. Sorry about that, man. A big part of that is the fact that you can find quality match-grade ammo for around $1.20/round in 6.5 Creedmoor. Without publishing the 6.5 signatures, could you tell us how the 6.5 mm compared to the 6mm in actual lbs of force? Thanks for this exhaustive, scientifically designed test. It was actually my phone calls with Jason from JEC over a year ago that got me thinking about doing this test. Surefire is an established and recognizable brand in the industry, so I was surprised to see where they fell on this chart. I actually didn’t test to see if there was zero shift between brakes. It’s fun. Glad this aligns with your experience. I think (hope) I can shed some light on why caliber specific brakes didn’t do much worse. For more info, check out. Phenomenal write-up as always. ; JEC Customs Recoil Reduction Muzzle Brake – I only had a JEC brake … Incredible work, I can´t thank you enough for the significant effort you have gone thought to supply us with facts instead of opinions. Your work on scopes was excellent and I am really enjoying the muzzle brake series so far. You bet, Eric! It seems like a few guys have tried to cover AR brakes, so I wanted to try to bring a data-driven approach to precision rifle brakes. I have a friend in the industry said he could get all the suppressor manufacturers to make a trip down. As the gas … Elite Iron OP COMP AR-10 .308 Muzzle Brake 5/8"-24 Thread- Parkerized. Hey, Chris. I actually already did that in a previous post. Thanks for your work. Looking at where the other brakes ended up on the 6mm and 6.5mm, I’d expect it to have similar performance. So I’d be shocked if it was even able to provide as much recoil reduction as what the Shrewd did, which wasn’t great. Or best by all of the above, but mixing categories isn’t helpful in a comparison, obviously. : +1-847-513-6201 How do we get a couple of your hats to give-a-way at our Sept 12 Match? vg6 precision (in stock) 5.0 (1) hellfire muzzle brake. Very interesting, just would be great to have list of brakes and picture of chris. I had quite a few disclaimers on that, because it isn’t an apples-to-apples comparison like what we’re doing for the muzzle brakes. Take a look at it’s ballistics compared to something like the 300 Norma and 338 Lapua … and look at the recoil you have to endure to achieve the same down-range performance. Well, that gets complicated with all the restrictions around them. Policy. It seems like a fairly persnickety design, but we’ll see if the performance makes up for that in the next few posts. What was the recoil in absolute terms for the 16lb 6XC/105 rig vs the 14lb 6.5Creed/140 rig, without any muzzle devices? SKU: OP-COMP-762. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; contiguous 48 states, DC and to all U.S. Military APO/FPO/DPO addresses. I was obviously a little disappointed by the results. There is actually a lot of great stuff on that website. I will have a whole post on muzzle blast a little later in the series that will try to give insight into that. Here is the data for the recoil reduction on the 6.5mm rifle for each muzzle brake: You can see the overall order is similar to the 6mm results, with the Alamo Four Star and American Precision Arms muzzle brakes still out in the lead. Consider this list to be your starting point in the quest for finding your perfect muzzle brake … - Long Range Hunting Online Magazine. A lot of people are concerned with that on suppressors.

I really like your approach and writeups, stellar job all around. A lot of people never think about that side of this. I appreciate you chiming in to help us understand the physics of what is going on with the caliber-specific brakes. That rotation could be mitigated by a specific (probably a per-cartridge design) neutralizing downward push .. or by removing enormous rearward push .. or by leaning into the recoil enough to limit any initializing motion, but that becomes more difficult for larger calibers, for continuous fire, and frankly for most lay users. Check out: http://precisionrifleblog.com/2015/06/24/muzzle-brakes-field-test/. Here are the muzzle brakes I wasn’t able to test on the 6.5mm rifle: Badger FTE Muzzle Brake – As I explained under the 6mm results, the Badger barrel clamp design requires a very specific barrel diameter at the muzzle, and it didn’t fit on this rifle either. I was excited to see how the empirical data stacked up to the hype I read online. I’ve just learned a lot about muzzle brake design through this process, and that is my educated guess. So I’ll leave you in suspense for a little while longer! I expected the caliber size of the bullet hole in the brake to make more of a difference. Although this happens in less than the blink of an eye, the felt recoil is spread over a slightly longer space of time. There is an average of 614 data points included for each line! Many are actually worse (especially if they’re shorter), and there may be a few that offer better performance. I was a little surprised by the separation too, but I think a large part of that is the angle of the baffles. Here is a different view of that same data. … When you do get around to the study of Suppressors my biggest question has to do with change in point of impact between suppressed and non suppressed. (For more info on this, see the previous post.). I’m also picky about the quality of apparel that my logo goes on, so that is a little bit of a hindrance too. To learn more about the cartridge, check out this article. A suppressor is limited on the amount of gas it can capture (based on the volume of the can), and eventually all the gas has to exit the suppressor along the same path as the bullet. I’ve become a pretty big believer in TBAC myself. Good work! Here is an example of the results I recorded for one of the muzzle brakes: As I publish these results, I plan to show how much each muzzle brake reduces recoil compared to a bare muzzle. It goes a long way. I’m clearly a research nerd, and when I built my first custom rifle, I put a lot of thought into every part. Absolutely, Steve. Tactical 5/8" x 24 Pitch Muzzle Brake 6 Inches .308 Custom w/ Black Finish 308. It also helps you separate the different types of recoil reduction, so you could place more weight on either overall momentum or peak force, if you thought one was more important than the other. 24 muzzle devices for .30 caliber are tested for recoil reduction on a Lancer Systems L30 Heavy Metal .308 (AR-10 / SR-25). Recoil reduction is the name of … Shop now and get Free Value Shipping on most orders over $49 to the So a good muzzle brake is able to do even more work in our favor on a magnum than a smaller cartridge. My 6XC rifle weighed in at portly 16.2 pounds with a bare muzzle, and no bipod or magazine. And, yes … there some brakes directed more blast back toward the shooter. The guy who taught me how to hunt and reload, and really passed on the passion for rifles to me, is now getting older and isn’t able to shoot rifles with a ton of recoil any longer. Price $174.99.

A couple sharp guys suggested I also display the recoil signatures of each muzzle brake overlaid on the same chart. This test is definitely in the books. It just takes more force to move the direction of aim, so I can hold more steady. But, Badger FTE brakes screw on and clamp onto the barrel. And remember what Professor Hall told us in the last post when he was talking about recoil calculations like what JBM provides: “While this method of quantifying recoil is useful, it ignores several factors that can affect the actual recoil force (felt recoil) transmitted to the shooter.” Meaning there will be a disconnect between the measured and calculated forces. No sir. Muzzle Brakes: Recoil Results for 6mm & 6.5mm, Vote For The Best 6.5 Creedmoor Match Ammo, Bullet Jump Research: Executive Summary & Load Development Tips. Like would an effective 308 brake mimic the recoil of a 243? JP Benny Cooley It’d just be putting up the money and building a couple things. I am a bit surprised by the results in that the Four Star and APA had such a margin over other similar designed brakes…but in all the ones I have used over the years…the larger open side chamber types are more aggressive at curbing that force and my personal perception mimics your results. For a precision rifle, this seems like the tail may be wagging the dog. Remember, we can’t accurately quantify that (as we covered exhaustively in the last post), because so many things play into it. There is some cross-over, but you can see there are some more popular in one discipline than the other. I consider those conversations my biggest payment for all the time I put into this.
