What muzzle brake for Sig MCX (Mass compliant) help?

[frayedends]

I just ordered a Sig MCX Patrol. Pretty much my first rifle in a long time and I didn't really shoot much when I had a rifle. But anyhow the Sig comes with a flash hider. I have to supply the FFL with a muzzle brake to replace the flash hider and be pinned on. I have no idea what the rules are, etc. I'd love for recommendations of what I can buy and have sent to the FFL that would work well for this rifle and be compliant.

Brakes suck for shooting at a range. And they don’t really offer any benefit on 5.56 because it already has almost no recoil.

Look at a comp instead. BCM Mod 0, 2A Arms T3 comp, or Battlecomp.

the 2A T3 comp is excellent. i've shot it side-by-side with an A2 hider and it feels similar in terms of blast. it also looks sharp and is cheaper than most.

2A Armament T3 Compensator - 1/2x28

DetailsThe development of the T3 compensator started with the need for a muzzle device that not only maintains a small size, but also performs well within its intended use. The T3 is a dual baffle compensator that directs expelled gasses to control muzzle direction. The initial baffle directs...

BCM mod O is great and have used it on a handful of massified rifles to good effect.

The BCM Mod 0, 2A Arms T3 comp is compliant in Mass? I don't know much about the law in Mass regarding comps, flash hiders, brakes etc. It's all new to me. I just noticed the Mod 0 says flash reduction.

The law doesn't define anything. The existing precedent basically hinges on what it's called by the manufacturer. Thus if it's marketed as a brake, comp, or thingamajig your good to go. If it's marketed as a flash hider, you're looking at death plus cancer.

My fave after a dozen is the PWS

I've heard from more than one person in MA the test is the following.... will a pinky finger fit in the hole of the device? If the answer is "yes" then there's a good chance it's considered an FH and not legal.

Granted this is purely HEARSAY and god only knows how courts see it. I stopped caring years ago. But for those who do care, it's probably not a horrible baseline to consider.

It’s annoying, but lots of stores stock BCM components.

My pinky or the cop's? Maybe Glidden has a calibrated pinky analog...

If my muzzle device is getting inspected, I'm already in trouble.

At the same time, this is useful data to be aware of.

There are a number of good comps clones of the Battlecomp, and i prefer those over any other comp. I also like linear comps a lot.

My favorite dont know if they are available

I’ve used the Bravo Company Manufacturing BCMGUNFIGHTER Compensator Mod 0 - 1/2x28 on both my Tavor and my MCX. They're advertised strictly as a comp and pass the “pinky test”. What I like about them is that from the side they look just like a standard A2 flash hider and they don’t add much additional blast/niose compared to a traditional A2.

PA has no problem shipping them to MA.

I have a Lantac Dragon on one of my barrels. It's a little expensive, but I got a deal. It works, but on a .223/5.56mm barrel, it's not like you actually need it.

Where muzzle device makes more of a difference for .223 is when you start getting into short barrel territory.

The MCX comes with a taper behind the muzzle, you will want a 90* shoulder adaptor if you are not using a tapered muzzle device.

Thanks EdMorse! I wouldn’t have known that. I will order one. Actually watched an unboxing video and it may actually come with one but not sure. The video here at about 2:20 mark shows a collar like part. I commented on it.
