Dude did a great test of over 40 muzzle brakes. Hooked his 5.56 up to a sled and measured the recoil force of each brake. The video itself isn't that interesting. What was very interesting was his performance vs cost data.
Video is here...

Note the prices...
Amazing (or not) how bad some of the most expensive brakes did. Also amazing how well some of the cheapest brakes did. Just ordered me a Venom Defense brake. :shaka:
I didn't post his .308 tests but you can follow the links in the video. He did a similar test for them too.

Good intel :thumbsup:

Lots of those designs aren't gonna make your neighbors at the Range very happy :P Good info though

i have some precision armament m4-72 brakes available if anyone is interested. bead blast stainless and black nitride :shaka:
its half the weight of the titan and an inch shorter. really effective and of course has the usual big boom associated with effective brakes.

Wonder about a regular A2 flash hider if it dampens some (if any) recoil.

For me, rather have effective flash hider for .223. Good, long video on all the different MB s.

For an all around device, I tend to run the BC and the AFAB. The SJC Titan is IMO the most effective device that I have used for reducing linear push and muzzle lift. I don't tend to run my SJC Titan much these days as it is very loud and really does not suit my shooting style and needs.
The below video is with the SJC Titan on a superbly built and balanced rifle. The intro on this video clip is with the SJC Titan with 10 rounds in a 3x5 card @ 5 yards in 2.11 seconds. Note how nicely the rifle grouped late in the string after I settled the muzzle oscillation coming from the low ready position. The rifle settles and puts the final 4 rounds in the same hole and results probably would have been similar if I had more rounds loaded and continued with the string of fire. Granted these results may not be typical to all shooters but the SJC Titan does indeed give me a noted improvement in the ability to reduce my hit zone spread at faster trigger speeds due to decreased movement and faster sight recovery. If shooting pure competition the SJC Titan would be my choice.

I have been looking for one but flash suppression I am more interested in. Also, I don't know why they didn't throw in the stock A2 birdcage in to compare to.

Because you don't compare Flash Hiders in a Muzzle Break review. It's kind of obvious.
I almost posted info on the flash hider I use, but then I realized that would be hijacking this thread. Maybe start a flash hider thread, or PM me for more info?

A flash hider would be similar to no muzzle brake as it forces the gasses up and to the sides instead of backwards to counter recoil. Should work to counter muzzle rise.

I would be interested in the A2 in there as sort of a baseline to relate things back to. Since many would have experience shooting with the A2 on. Maybe a muzzle device test would be more appropriate title...
Most of my guns have the standard A2 and I currently have one with a BattleComp. The only other muzzle device that I have personal experience with is the PWS FSC 5.56. The PWS was on a good friend's gun and I like it, but like many of the more effective devices, it was pretty loud. Not for the shooter, but if you were anywhere outside say a 45 degrees angle either side and behind the shooter, I could really hear and feel it.
When I first got the BC, it didn't seem that loud. Then since most of my guns have an A2, I noticed that the BC was pretty loud. Not quite at much as some other devices, but still much louder than the A2.
There are many others that I've seen in competition and training. Some almost funny how they seem to spit a fireball, even visible during the day.

I think the bare muzzle as a baseline is appropriate for this particular test as there is a big difference in a flash hider vs a brake or compensator especially when it comes to classification of a rifle in the states that look at features for rifle legality, so I do think the distinction is important. The A2 has little effect on compensation, but it does a good job when it comes to flash suppression. There are also tests out there on flash suppression and on muzzle devices in general.

This compares various muzzle devices, you can compare bare vs a2.

Ahh. Thanks. I recall a video of someone doing A2 vs a bunch, but it was more subjective and also compared flash.
I have done some side-by-side myself, but very limited.

based on Jeremy TTAG's tests, i've used the PA M4-72 on several builds. it is very effective, and does a really good job of deflecting the blast rearwards to mitigate recoil, sometime you get spectacular fireballs coming back towards your gas block. however one thing i found out, is if your handguard extends up to near where the brake is at, e.g. 14.5" barrel with 12.5" free-float handguard, then you get burnt powder fouling all over your handguard and front BUIS. kinda a PITA to clean up afterwards, all those nooks n crannies, Hoppes #9 & Q-tips, e.g. keymod, picatinny. seems like you you need about 6" between the brake and front of handguard to avoid this. consequently, thinking of switching over to VG6 and/or LANTAC. humbug though with pinned/welded 14.5" configs. it's either that, or shorter handguards.
the VG6, LANTAC (and most others) direct the blast straight sidewards, instead of rearwards, which of course makes them less effective regarding recoil mitigation than the M4-72, so it's a trade-off.

Being a curmudgeon raised on the M-14, I have no idea why the 5.56 needs a muzzle brake.
A .308 without tuned gas system, maybe..............

Curmudgeon perhaps, but I doubt that you are clueless on this one. Therefore, I am pretty sure you have an idea why some may opt for a muzzle brake on a 5.56 and the benefit that they may derive from its use. On the other hand, I think that the needs of others may not necessarily match your needs, therefore being the "curmudgeon" that you say you are you, that is what drives you to poo poo it.
