Need info on AI muzzle breaks

[Jgrovem110]

Hey guys just purchased an AIAT and I'm looking for a muzzle break, my question is can the AI muzzle break be installed at home or does it require a gunsmith? i know there's much better options out there but i just like the classic look of the AI break.

Should be good to go without any modifications.

I use the Area419 Hellfire on my AT and it is awesome.

The issue with the AI brake is it is a metric thread versus the standard 5/8-24. I have an AI brake on my AXMC as it came with it and it works nice

 

[Jgrovem110]

Oh okay I did t realize that .. so it’s not gonna work with my AT?

It’ll work if you buy a metric threaded barrel for it. Otherwise you’re better off with a Hellfire

 

[Jgrovem110]

its the factory UK barrel but im fairly positive its 5/8 thread

i also see badger ordnance makes the FTE break which looks identical

why so much hype for the area 419 ? is just the most effective and easy to install?

If the original barrel is an actual AI barrel, I would think it is a metric thread but you should certainly figure that out before you buy anything. Furthermore, I don't believe that the AI brake is made in any thread other than metric so if you believe your barrel is 5/8-24, then you can't use an AI brake

There is really no more hype for the Area 419 Hellfire than any other high quality brake. I like the Area419 as it is what I have used but there are other brakes around like the Little Bastard, etc. All have their followers.

My 6,5 CM AIAT factory barrel was 5/8-24. I think some of the 308 and maybe the larger cal barrels were metric threads. Shouldn't be too hard to confirm with a 65cent nut from the hardware store.

I like mine because I can change between an effective brake or run my suppressor in the matter of seconds. And they’re easy to install to lol

I am not sure of the accuracy of what I was told but I will say it anyways.

Any barrel purchased with an AT that is not 7.62x51 is not a true Lothar Walther (Factory AI) barrel. When you purchased your AT with another caliber, I believe that the barrel is a US made barrel from Bartlein and that is why it has a conventional 5/8-24 thread.

Not sure if that is accurate. I bought my AT in 2015. There was no option for purchasing an AT in any caliber other than 7.62x51. I did buy a 2nd barrel with it in 6.5 CM but that was a Bartlein not an AI LW barrel.

And all my bartlein win tac barrels have been absolute hammers.... Just saying

 

[Jgrovem110]

it has all the uk proof marks on it so idk

 

[Krob95]

Did you buy it new? If so call the people that sold it to you, and ask them what size muzzle thread it is. If it’s a metric size get the AI brake. If it’s standard 5/8’s get w different one.

Post a pic of the muzzle threads? Do you have calipers?

 

[Jgrovem110]

sounds good ill check it when i get the chance

Yes they are

That is news to me but thanks for pointing that out. Wasn't an option for me.

 

[TheOfficeT-Rex]

My 2018 6,5 CM barrel also has the UK proof marks.

It's also a hammer.

Be a American and Get a suppressor

Can’t live a state where they are illegal ...

I happen to have a spare AI 18M x 1.5 brake, but it’s off a 338 so I’m guessing it’s a larger thread.

Honestly, this is not complex. If it is a AI factory barrel, it is either M18x1.5 (regardless of caliber) or it is 5/8x24, unless you have a ASR which is 3/4x24 which is not the case.

Simplest solution, post a pic and this will be closed in 0.5secs. Or google it.

Best way to tell if it is M18x1.5 is if there is a step down from the barrel diameter right before the threads. This is where the clamping portion of the brake connects. Looks like this:

And, yes, a AI brake can be installed at home with a 4mm Allen as long as your barrel is M18x1.5
