Muzzle device opinions/experiences for SBR...

Picked up a PWS TTO Brake this past week. Haven't got to shoot with it yet but is supposed to be a nice rigs, and said to make a difference in rise and flip.

I have a Troy claymore on my 16 inch AR-10, an Allen Gunworks linear on my non restricted ACR 223 barrel, an S&J linear on my non restricted ACR 300BLK barrel, an S&J linear on my 12 inch 300BLK AR, a PWS triad on my 12 inch PWS 223 AR and a modified S&J linear on my 9mm AR. The linear brakes don't do much besides make it more comfortable to shoot by pushing the muzzle blast away from you and everyone around you, the triad holds the muzzle down slightly, it's a little louder but is still very manageable for noise. I had an S&J linear on my 6.5 inch AR and it made that rifle fairly comfortable to shoot.

The only way the linear comps could reduce muzzle rise is if the vented upwards which they don't and the only way they could reduce recoil is if they vented out the sides at a backward angle which they don't. The only way I think they help in either department is by adding mass to the muzzle.

I had a Rainier Arms mini comp and it worked very well for reducing muzzle rise and recoil but it was loud. It wasn't bad on my 14.5 inch AR but for some reason it was painful on my 12 inch AR. I'm not sure how the 2.5 inch difference in barrel length made so much difference but it didn't last more than a couple trips to the range before I put it back onto a longer barrel.

I really like the PWS triad, it has the cut between the upper opening between the forks cut a little deeper which is how it pushes down a little and it manages muzzle blast and flash decently. I don't notice recoil much on that rifle because it has always been a very smooth shooting rifle with the piston system and now I have an Enidine hydraulic buffer in it and it hardly feels like much more than a 22 now.

What length is the barrel you're working with?

It's gonna be for a MK18, so 10.3". I'm starting to develop an interest the Griffin products. Gonna look into them a bit more...maybe a Tac Comp or a Flash Comp with their new QD blast shield...

By the way Chris, thanks for the awesome info brother. That really shed some light on a few of my concerns...

I have the FSC556 on a 16" barrel AR which is the TTO with flash suppression. You'll like it. I haven't tried it on my SBRs. Maybe I should. :)

Hey C, in terms of how loud it is, would you say that it's pretty comparable to any other comp, or do you find it a bit more discreet? I know it might be a long shot of a question, but if you've had a go with a few comps, maybe you'd be able to make out the difference...???

The GA brake is a bit on the loud side. Not too bad from the shooter or guy behind you. Sounds a bit louder than my FSC556 and Triad. I sold my Triad for the GA. The GA felt more stable when doing double taps.

No probs.

GA now has a Blast shield,which may be an option, MM did a good review on it & the flash comp as well.

Oh man, I just peed my pants a little. That's awesome. Now I could have a FerFran clone without having to get rid of my M4SDIIs. Thanks for the heads up!

Wouldn't the blast shield just turn it into an even more expensive linear comp?
Nice to be able to remove it and essentially have a two in one muzzle device but a guy will probably end up with a preference one way or the other and just leave it alone after figuring out which way they like it better.

For a 10.3 inch I would stick to a linear of some type, maybe the Griffn Tac Comp with it's smaller vents would give a little bit of a brake effect without being overly noisy but I've never seen one so can't say for sure.

If you go with a linear then look into things like a heavier buffer or the Enidine hydraulic buffer to help with recoil management while still letting you keep the muzzle blast downrange where it belongs. This all depends on how well the rifles gas system is balanced with the spring and buffer though, If the rifle cycles a little harsh causing some muzzle jump then a heavier buffer or the hydraulic buffer might help but if it's well balanced and smooth shooting from factory you probably won't feel the need to change anything.
It's always a sacrifice though. You can either have nice and quiet with a linear or you can have no muzzle movement with a well tuned brake. I was shooting with a buddy a few weeks ago and he has a single chamber brake on his rifle and he was shooting so fast I was amazed he was actually ringing the 50yd gong most shots, his rifle really barked though and shooting mine was more comfortable but not as accurate when shooting fast. I needed to slow down in order to be accurate. The only rifle I can shoot close to as fast as him is my 9mm AR but that thing barely moves when shooting. He also shoots 3-gun regularly so I'm pretty sure he's a better shot than me when standing shooting quickly freehand. I need more practice :)

True...but I think you hit the bullseye with "...essentially having a two in one muzzle device." For me, having that extra small option goes a long way. I know that I'll never end up having to engage in a real life CQB fight where all this stuff makes a world of a difference, but the course of fire that I'm on that one particular weekend may need a little mod to my primary. Plus, it looks friggin awesome!!!

Very true, and for us civilians looks is often the most important feature ;)
The standard linear sure doesn't look very impressive but it works. The Claymore does exactly the same thing but looks 1000x better.
My biggest hangup is that I have a hard time justifying spending more than $100 for a muzzle device.

I hear ya brother...especially when there are so many different muzzle devices out there. It can get pretty damn expensive to find just the right one. Unless you have the opportunity of trying them out before actually buying them, it becomes a bit of a gamble. I mean, from what I've been reading online and in a lot of the posts on this thread, you can pretty well determine how a muzzle device will affect your rifle even before you fire it. But all said and done, you'll never really know until you physically put it under fire...

But you all know how the saying goes, "You gotta pay to play!"
 
The GA Tac Comp & Spikes Dyna-Comp look very similar. I've got a bunch of devices planned for Mk18, we'll see how they fair in terms performance AND annoyance at my local club :nest:
 
I guess we are lucky over here in NZ, I use the NEA minican. The Crusader muzzle brake that came with the rifle is friggin crazy loud on my 12.5" NEA and I hate it. Loving my minican however, much better when I am engaging multiple goats while on search and destroy jobs. I am a pest contol operator and the NEA is quite handy on goats......

That's awesome! Over here, I am a paper target population controller, and my Daniel Defense does a good job at enforcing that!
 
Just another thing that came to mind...after looking at a few different manufacturers of comps and brakes, I noticed that most of the higher end muzzle devices are supplied with a set of shims rather than a crush washer. Is there any difference between using either one? I'm getting the feeling that there is a reason for each one...

i prefer shims over crush washers myself. some barrel require an awful lot of torque to get a crush washer properly indexed where as a shim set just takes time messing with size combinations

In the case of the Precision Armament EFAB, the exit hole of the comp is almost the same diameter as the bore, so any cant could result in a strike? with or without a can.
