View Full Version : KAC MAMS Brake 5.56MM
Have any if you had a chance to try out the new KAC MAMS brake ? I have not read any reports about how effective it is compared to others but if its like any other KAC product I've used I'm sure it's great.
Also does any one know a good source that can get these ?

They only have the 5.56mm in stock.
I have one on a KAC 14.5 upper and the same upper with a Surefire MB556K. Seems to reduce recoil and flip about the same as the Surefire, or at least to where I can't tell a big difference. Biggest difference is in flash reduction. The Surefire puts out a huge bright flash to front and sides, and the MAMS makes a small muted ball similar to, but larger than a KAC 3T. I've shot it in a class and none of my classmates griped about the concussion like they do with the MB556K. It also brings my barrel length to about 16.2 inches when P&W'd.
Ordered one from SKARMS as well, was to my door from Texas to the east coast in 2 days
Not a user review but heres some pics of the 556 version next to a battle comp 1.5 for comparison
only thing that bugs me is the size of the hole pre drilled for pin and weld, i understand its part of the process for the TDC indexing pin on top but wish it was smaller,
a #11 drill bit fits snug in it but im afraid to use that and having to go to deep to catch the OD of the bit so the pin sits square inside.
( i would be using a cut piece of the shank of the #11 drill bit for the pin) but other than that for intial impressions cant say a whole lot more until i try it out.

I have exactly the same set ups. 1 KAC 14.5 upper w MAMS and 1 14.5 w surefire MB 556k. Basically, had the same experience too, although ive found the mams to have less recoil or smoother if that makes sense. MAMS puts out signicantly smaller fireball--I tried them both at night, dusk and day. MAMS is also much less obnoxious than the SF brake but it can be a bit loud on an 11.5".
It's nice to have one but I don't know if I'd pick up another especially since I don't have KAC 556 Suppressors.
I'm much more interested in how the mams will function on the KAC 762.
I have no intention of suppressing my rifles at this time. This is a very expensive brake but if it does as good of a job as the mb556 without as much flash it has my attention.
My only concern with brakes like these are how they stand up long term at higher round counts.
not to purposely sidetrack but since were on the topic of the mams how well does the the Griffin MRSD II stack up? shown below. If it's say 80% as capable as the mams then for the coin I find that intriguing.

Nuttinfancy did a great overview of the M4SD on YouTube. Almost got one based on that review. But since I'm running an SR15 as my primary I decided I wanted to keep it in the family an opt for the MAMS. If you're full time active duty military or LE, order direct through KAC for a discount.

You'll be pleased then. Better all around than the mb556 except it doesn't act as mount for the surefire suppressor :(
I only have put about 1K rds thru mine, mostly in your neck of the woods. I just moved from N. VA otherwise you could try mine out. Btw, Robb Jensen at VA Arms does a great install.
In case anyone was curious i just noticed that the first 5 front rows are
drilled at an angle which i guess accounts for the recoil reduction of the brake.
Just thought it was pretty cool and wanted to share
as i haven't found much detail on the device online for those interested.
Not the best pics but its as good as my phone would get me.
( in the first pic the brake is not installed upside down lol, just had the upper turned over in the vise)
i think i remember reading somewhere that they forge the parts but I'm not positive and may be way off, hopefully someone from KAC will chime in.

Hope this works. Never tried linking video before.
Not great video--too short. Longer piece had to be cut. Only 3 or 4 shots. Taken in slow motion with rifle loosely held. No sound.

I think that it works very well.
Notable recoil profile difference when a can is put on, proving its effectiveness when it is allowed to port as designed.
Can't comment on the suppressors at the moment, sorry.

I put the Griffin on my SR-15 Carbine. I would rather have the MAMS but got tired of waiting to find it in stock (always done poorly with managing "instant gratification"). I don't have a lot of rounds though the combo but, thus far, it seems to do the job.

I would ask someone from KAC about that. I know their products do evolve and while the post did seem a bit silly it was supposedly for indexing the can. Perhaps they found a simpler way to accomplish the indexing?
Thanks Buckjay, I sent KAC an email and if it is an evolution of the product I'll post it up

The post is the suppressor index pin.
It should have been installed prior to shipping.
It is not necessary if you aren't going to use the MAMS as a suppressor mount, however, if you would like to return it to be fixed, please let us know.

If you can pull the A2 FH you will have the same clearance to stick the MAMS on. The only issue is if your barrel shoulder is recessed behind the handguard, and even then, as long as you can fit your wrench and hit torque you are good.

I've been told this brake may be part inconel and partly made of some other steel. I do not know if this is true or not and I don't know which part is what.

Mr. Leuba,
Can you comment on what this device is made of and how it is out together ? The end cap appears to welded to the body of the brake.

I bought a 7.62 flash comp and it came with shims so I'm pretty sure the 5.56 version does too.

Figured as much. Just wanted to be sure. On second look it looks like a peel washer mounted there. As many times as I've been tempted to pull the trigger on the Griffin Armament comps I hesitate before I hit the "Proceed to Checkout" button. In the end I think I'll regret not waiting for the MAMS considering I only want to add components I really want, but not necessarily need. I don't doubt the MAMS will perform as expected, with the added bonus of it being a kick ass looking muzzle device.

I'm looking forward to hearing what you think about the comparison between these two. I currently have no plans for a suppressor and the MAMS would go on a Noveske N4 16" Recce rifle.
I wanted a muzzle device that will be as effective or at least almost as effective as the MB556 but without as much flash and concussion.
"Did it come with the shim?"
I sent the upper off to Adco and that is what I got back so I'm not sure if it included the shims or not.

Not trying to derail, but when I got my griffin NT-4 compatible mount, it came with peel washers. Unlike my TTB that came with knights shim set, which I would prefer.
Have any users noticed erosion inside the brake ? The distributor I emailed stated that this brake may have an inconel blast baffle inside it which I assume is there to help slow down erosion against the end cap. Can any one confirm this ?
Thinking about the fact that this piece is sacrificial makes me take a second look at an inconel triple tap for $100 more.

Inconel in the triple tap brake is a wear resistant material, no doubt (I don't know what the MAMS is made of). 17-4 in the NT4 comp is stronger and harder but probably has similar wear resistance when compared in the application (muzzle brake / comp). I've not seen any photos of compensators from either manufacturer that were worn out so it's probably a zero sum game. When people say "sacrificial" they are implying, "takes a percentage of wear so the suppressor doesn't have to" more than, "these wear out rapidly" in my opinion.
The peel washer is an encapsulated stainless steel shim set. Grab it with a pliers and heat it red, water quench (for the purpose of saving time), grab in a different area, repeat, and the shim set seperates into about 20 shims now that the laminating adhesive is deactivated. Takes about a minute to do that. I agree shims are more convenient, but for $325 more (additional cost of TTB), I'm not sure the shim set is worth the squeeze.

Nice video link! Ild bet the reason it's hard to find a video is that not too many people own a mams brake. I noticed the Triple Tap Brake was an item major distributors would stock only about 3 of at a time. That suggested to me that price keeps volume low.
Well it arrived yesterday and I hope to stop by VA Arms either tuesday after work or wednesday to have it installed.
I'm hoping to get it zeroed on Wednesday but I'm not sure if I should wait till the rocksett dries and cures completely.
It included a 7 piece shim kit and rocksett.
It is interesting to see the holes are drilled in different angles into this. There is also a pre drilled hole on the bottom for those who want to get it pinned I'm assuming.
Definitely no inconel inside this as far as I can see it all looks like the same material. Finish is missing in a few spots at the bottom but that's no big deal.
I'm looking forward to putting some rounds down range with this.

Youll be set. Robb installed at least 2 for me (lived near there until recently).
There's another reason for the hole in the bottom of the mams, hopefully he won't have to use it. He had to on my first one--no problems, but a bit out of ordinary.

Last week I got a better video of the mams but still in slow motion. For some reason the video of the surefire MB didn't take.
I'll try again next week.
Robb is awesome. The guys at Va Arms, especially Bernie and Robb, have consistently gone above and beyond to help me out.
Robb has helped me out more than any one else or any company has and has with AR's. If you read this Robb I just want to say thank you.
Va arms has a customer for life thanks to Robb and Bernie. I bought my last three guns from them and recommend all my friends to go there for any of their needs. The guys there are squared away and good people.
I'll buy any thing I can from those guys.

The hole opposite the pin is to seat the pin, not for welding. The metal behind the hole is too thin for a good weld to hold.

The rifle it is going on is a mid length gas system with NSR rail and an A5 receiver extension.

Heres a few vids of my cousin firing my rifle with the mams, it was his first time shooting an ar15 rifle and brought him out just to have fun for the day.
His hold is pretty relaxed to give you guys an idea. pleases excuse him and the jpc hes wearing.
I only brought one chest rig and the jpc, so he wore that with just plate backers to carry mags around being as i wore my rig.
Not the greatest vids, didnt really plan on using them for this, if not i would of showed more of the brake.
Ammo was PMC xtac m193
14.5 noveske n4 midlength

Yep, you can see a flash in all 3 vids between different shots, the PMC probably had alot to do with that.
Standing next to it wasn't to bad in my opinion, but then again all i have to compare it to is the bcm mod1, bce 1.5, fsc 556.
It was very comparable to the battle comp as far as side concussion imo with just a bit more umph to it, it still gives off a nice thud in your body if your standing next to it, and i noticed just a few particles smacking me in the face but nothing terrible.
Wish i spent more time evaluating it but it was the first time out with this particular rifle and i was
messing around with zeroing it in, checking the brass etc etc and making sure my cousin was having a good time.
next time i go out i will try and get better video and comparison to what i have on my other rifles.

Anyone thats shot both the mams & battlecomp, which did you prefer? I cannot decide between the two on my kac 14.5
I'm not planning on suppressing it, looking purely at recoil, blast, and flash reduction

Wow,
I know I am going to catch shit for this, but that is without a doubt, one of the ugliest adapter I have ever seen. And I have seem some UGLY, prototype shit on military weapons.
I am a function over form type of guy, but the thing looks like it was build in a middle school shop class out of spare parts. Whoever designed this over at KAC, needs to take a nice vacation for a few weeks to clear their head.
Please tell me what it does that the other adapters on the market don't do, at 1/2 - 1/3 of the price (besides can mount). Couldn't they come up with something a little more refined?
Really? Personally I find it aesthetically pleasing because it is rather abstract in form.
I think it looks pretty cool. I did not get it for the looks though. It is certainly a very unique looking brake.
I don't really think the looks matter as it's a can mount, first and foremost.

Are you talking about the MAMS?

Yea. I get the detends, its a pretty slick way to mount the can.
What I don't get, is people buying the mount who have no intention of running a KAC Can.
There are much cheaper comps/hiders that have very similar, same design for a fraction of the cost. And they don't look like a drunk guy welded them together either.
I love Kac products, in fact my go to rifle is a Mod1, but some of the shit makes me scratch my head. A fool and his money and all that comes to mind when I see this.
Feel free to change my mind. I want to BELIEVE! Seriously, if you are trying to sell me this product, why this over a BC, Dyna, PWS or Griffin (sans mount obviously)?
Thanks
Has anyone installed a MAMS on a SCAR?

Thanks! Oversight on my part. Was just too excited about the MAMS.

Will pinning a 5.56 mams on an sr15 void the warranty like another manufactures muzzle device will?

In short, its awesome. Will be awesomer when dealers have QDC CQB cans in stock ready to do form 4s.
Since nobody else can make a comparison video I and a buddy will be soon. This is ridiculous. The shop I work at just got four in. I snagged one for myself.

Please provide some insight on flash suppression capabilities compared to a standard A2 as a baseline if you can.

Yes.
Any alteration to the non-furniture parts not done by an armorer certified by KAC for the work performed, will technically void your warranty.

What is the recommended procedure to get this done and who is a smith that can perform this and not void the warranty? Marvin Pitts? And will shortening to 14.5" and pinning void it?
Hey dude, I got it mounted today and shot a buddy's SR15 with A2 back to back. The MAMS on a middy is like shooting a .22. It's crazy. The flash, from the shooters perspective is non existent. From a side profile it's there, but it's a red/orange glow compared to a flame or flash. Concussion is stiff, but not as bad as a PWS or SF MB. Ammo was 55 gr independence xm193. Barrel length on both was 16".

We do not have anyone on the "approved" list for cutting a barrel, or for pinning and welding. We strongly recommend against cutting a barrel. There are reputable companies out there that can do a pin and weld if you want to go that direction, and done properly it should make no negative effect, however, if an issue arises, the company that made the alteration to the firearm as shipped will be responsible for getting your gun working again.
ETA: If I really wanted to change something about the configuration that would void my warranty, I would check the system as delivered for a couple thousand rounds to make sure everything was good (and to ensure that I really needed said change and not just more experience on the gun), and make the change. KAC isn't going to turn its back on you for making an alteration, we simply won't bring it in and fix it for free. You can still get parts to make repairs (which will most likely be outside the 1 year warranty period anyway), and we will still help you with technical questions. KAC simply has to protect itself from those that don't know what they are doing and breaking guns by "fixing/upgrading" them.

When shot at night you can actually see individual flames coming out of the small holes in the MAMS. It's a bit unique. Usually there is just a fireball the muzzle adapter usually just determines the size. The same holds true for the MAMS. I fired the MAMS and SF MB both (on KAC 14.5 uppers) one after the other at night. The MAMS fireball is a fair bit less than the SF MB, but no surprise there as the SF MB probably rivals a flame thrower at night (but I didn't have a flame thrower at the range so I'm just speculating). :D
I forgot to say that I shot this at the indoor range that I work at with all of the lights turned out. My buddy got some video of it and the A2 back to back. Hopefully he can post it soon.

just got my 14.5 upper & mams back from rainier arms. 6 day turnaround and the pin job is flawless. Can't wait to get it to the range this weekend

^ that looks great. I should be getting my 14.5 and Mams in soon too.
For those who have a MAMS, could you measure how far from the base until the holes start?
I'm wondering if a Noveske 8.2" 300 BLK barrel + 7.62 5/8"-24 MAMS would clear the upcoming BCM 9" KMR?
I don't have any current plans for a can, so obscuring the mount is not a show stopper, although it might also be interesting to know how far from the base of the MAMS to the edge of the KAC compatible cans as a data-point.
I'd appreciate any thoughts/info on this.
Thanks,

I guess it would depend on what you mean by "clear". I can measure the distance on a 762 mams tomorrow from the base to where the holes start. Mind you that the 762 mams is longer than 3". Here's one on a 13.5" 762 barrel. OAL is almost 17". I'm thinking you'll be just fine.

^^^ That is so f**king nasty ^^^ I want that upper so bad! :) Seriously, the aesthetics on that upper is unlike anything I've seen, and obviously the functionality is equally as impressive.

I just want to make sure the blast is outside of the rail.

Thanks. I should be getting back from Marvin Pitts soon. He's been working some do his magic on it.:dirol:

The holes start almost 1" in (7/8).

If anyone is interested, I found the 5.56 MAMS on sale for $269 shipped here ; http://tradingplacepawn.com/shop-online/by-brand/knights-armament/knights-armament-556-qdc-mams-muzzle-brake.html
Around 4 months ago they also had the KAC 5/8 x 24 for $299, now $350 and OOS.
How does the MAMS compare in recoil reduction in comparison to the battle comp on a SR15?

For anyone who is interested, an 8.2" + MAMS doesn't clear the KMR9. I probably could have figured this out without trying it, but I didn't quite know how each of these components are measured.
Looks like I'll be doing some cutting...
