Hi, and welcome to THR.

Might I ask what you're planning to use this for?

Good Luck,

King Armory makes some of the best Breacher/Muzzle breaks I have seen. They are installing one on one of my barrels for me. They are brazed on which is a very strong setup. Shotgun World Tactical shotgun forum (The Basement) is the place to go to ask this question. There are more members there who have experience in this area.

Here is a review done on one of their muzzle breaks: They have a Breacher/Muzzle Break also that has a crown with teeth for breaching.

King Armory will install it for you. Their website Link:

Also if you have the 590A1 with a 18.5" bbl the Mossberg 500 breacher barrel will fit it.

Somebody correct me if I'm wrong- I am obviously not the go-to Mossberg guy around here- but I thought the 500 barrel had a mounting screw to attach it to the front of the magazine tube, while the 590 had a barrel ring and a magazine cap to hold it on...

I guess you could use it if you forgot your house keys.

The Mossberg 500 Breacher, Mossberg 590A1 18.5' BBL, Mossberg 500 MilsGun, Mossberg 835 all have the same mag tube setup. I make mag tube extensions for all of these shotguns so I am speaking from experience. The 500 breacher has a heavy wall bbl just like the 590A1 shotgun.

Here is a Mossberg 500 Breacher with one of my tube ext on it and a 590A1 18.5" bbl so you can see they are the same. They both have +2 (7+1) Tube extensions on them. I am the only one who offers +2 extensions for these shotguns. Vang makes a +1 extension for them.

Exactly what is a breacher... and why does one need its particular modifications?

[MAX100]

It is much safer to breach a door with a good breacher attachment. The crown with teeth allows the muzzle to dig in and get grip on the door. By having the muzzle pressed firmly against the door the chance of shot bounce back is lessoned. The ports and the crown allow gasses to escape and they push flying material out laterally away from the gunner lessoning the chance of blow back and reduced likelihood of injury.

You can breach with a plain barrel shotgun but it is much safer with a good breacher attachment.

Breaching rounds are much safer to use than buckshot or slugs. Breaching rounds are encapsulated slugs made of lightly compressed metal power and turn into dust on impact. You don't get bounce back with them but there is still a chance of flying debris blow back.

cool thanks.

[GunZ_72]

i 500 breacher barrel will fit a 590. but definatly not the 590A1. a 590a1 has a 20 in barrel or a lil more with full length mag tube that holds 7 rounds. the barrel has 2 rings one is for a bayonet lug the farthest fwd ring is the locking ring for the barrel screw.

if you need pic i will post some.

but i can tell you a 500 barrel will not fit on a 590a1 militery.

but i can tell you a 500 barrel will not fit on a 590a1 militery

We all know the 500 breacher bbl won't fit a 590A1 with a 20" bbl for the reason you posted. I was saying it will fit a Law Enforcement & Military 590A1 with a 18.5" bbl. I post a picture of what one looks like. Model #'s are 51517 & 51518 these are the ghost ring sight models. There 3 other models without GRS.

How can I purchase one of your tube extensions? and would it need to be shipped to a FFL...
This would be used on a Mossberg Rolling Thunder Shotgun.

I'm still a big fan of poking the bayonet through the mail slot first.

This is "SWEET" Mainsail...
Where can I get me a bayonet like yours...?

[Jack2427]

A breaching attachment is like, and can function as a muzzle brake depending on the design. The reason we spell it like a car brake is because that is what a muzzle brake was initially (and currently) intended to do, reduce recoil. Some breaching attachments are just points filed onto an existing brake or compensator, others are purpose built for taking out door hinges.
Most civilian SG users are better served with a muzzle brake/compensator instead of a breaching attachment. If you want to shis ka bob the BG, use a bayonet, its more effecient than sticking him with what amounts to an ineffective pickle fork.
Just a thought for Gunz, I have participated in taking down a number of vessels from yachts to really large commercial vessels (ULCCs). On most yachts you do not have to breach anything, a good kick will take out most doors/hatches. On commercial vessels or warships a breaching round is useless as the hatchways, portlights, and like entrances will be real solid steel, not very amenable to shotguns rounds of any type. I suspect that hatchways with exterior hinges might be vulnerable to such rounds, but a sledge and a pin would probably be faster and less dangerous to the boarding party.

Is there any reason you couldn't have a screw in breaching choke/break?
It nearly goes without saying it would be cylinder bore, but I say it just so we are all on the same page.

Edit: well looks like I had the right idea; a quick search turned up just that:
http://www.benelliusa.com/forum/showthread.php?t=15235
Too bad Remington isn't marketing them separately yet.
Hopefully some other maker will figure that out and produce some in the usual non-Remington choke tube thread pattern. I know I would buy one.

Second edit: looks like that barrel/choke combination isn't rated for breaching,
http://www.glocktalk.com/forums/showthread.php?t=955803
but i still don't see why it wouldn't work in principle.

Third Edit:
If you have a bayonet lug and you are not too worried about the strength of the point of your bayonet, (the OKC3 I have is like a sharpened prybar!) you could use that as your standoff when breaching.

Knife Knut asked,

Check the third post in this thread. Wad Wizzard is what you seem to be hunting for.

GunZ_72,

Give me a e-mail at clements@pro-patria.us. We have some kit out at Crane now for SOF. Already have a Safety Cert for the Army. Which NSN model are you using?

[Hans Esker]

What I meant was a breach choke that was compatible with the existing standard of barrels threaded for choke tubes, rather than that device.

[oletymer]

Where do you live, Watts, Harlem ?

The government (.mil) issue Mossberg 500/590s do not have screw in choke tubes. Cylinder bore is used because of the various special munitions that are employed. You might be able to have them installed depending on the local commanders and contracting officers, but there is no "Safety Certed" way to do so.
