Hi I'm pretty new to guns and shotguns and I was wondering if the muzzle brake on the 500 Road Blocker is removable? And if so how do you get it off.

If you don't already own one, the best choice might be to avoid the issue all together by purchasing a more conventional Mossberg 500. The Road Blocker is not an especially practical gun and the muzzle break on it is not very functional. If you do a search on it, there is another thread about that gun somewhere.

I haven't seen one up close so I am afraid I can't answer your original question but at least this bumps your post up.

Welcome. If you're new to guns (or even if your not) you will find lots of good info here.

From the looks of it, it appears to be screwed then pinned on attachment. If the barrel is 18.5" with the attachment then it's best to try and sell the barrel and just purchase a home security barrel (plain) as they are called.

The brake has ports in it which dont count towards the full length of the barrel, only the muzzle end. So it's not slipped on or anything. And if you somehow unpin it and remove it, then it's a short barreled shotgun once the new muzzle is less than 18" and you better have the ATF approved stamp to go with it. In other words, it ain't worth trying to remove.

Best and easiest option is to buy a security barrel which are cheap and plentiful and put yours up for sale if you already own it.

OUTSTANDING!


The best way to deal with that brake is to get a conventional stocked regular barrel shotgun in the first place.

If you take that thing off you're going to completely ruin its value as a boat anchor.

The pistol grip might still be able to find purchase in the lake bottom but not near as well as the sides of the brake.

the break can be removed. It takes a special tool and is tourqed on to about 100 foot pounts.

It will look something like this once you have it off.

Not that I know were this design orginated, just not happy were it went :oops:

Mossberg apparently does not have the specifications listed on their website for the #50591 Roadblocker, but elsewhere I found that the barrel length is 18.5" with the muzzle brake and the overall length is 28.75". So I understand that to mean that the barrel length including the muzzle brake is 18.5" because the overall length of #50591 matches the 28.75" OL of the Mossberg JIC Cruiser. If that reasoning is correct, the Roadblocker muzzle brake is permanently attached, because if it could be removed the remaining barrel would be under 18", creating a SBS. So because the muzzle brake surely is permanently attached, BATFE could put that barrel in a vise and take a pipewrench to the muzzle brake, and the barrel would be destroyed before the muzzle brake weld fails.

Do yourself a favor and consider the Mossberg #50665 590 Special Purpose, 9 shot, 20" barrel, matte blue finish, heat shield, bead sight, and a black synthetic SpeedFeed stock that holds four extra shells so that you can skip a sidesaddle and have a gun with good balance. And replace the bead with a XS Big Dot tritium sight, and put a good two-point sling on it. Good luck, tdk213, and welcome to the Basement!

The barrel is listed as 18.5" which is correct. The barrel is basicly the same barrel as the Tactical (below) with differant machining steps to finish the barrel. It does not include the "brake" in the measurement and if you look closely you can see the jam nut that retains the brake.
Image
The Rolling Thunder also uses the same barrel machined the same as the road blocker, but with a differant muzzle device. They do however list the barrel as 23" vs. 18".
Image

Look closely at the 18" Mariner and you can tell that the threaded portion of the barrels inside the muzzle devises will also come out at 18", so the barrels are 18", but the devices are longer.

Welcome to the Basement tdk213 {hs#

I think you will find that most of us here have a pretty low opinion of pistol grip only shotguns with Hollywood stuff hung on the muzzle. Not because we object to anyone owning whatever floats their boat, but because we tend to be a bit more practical in our approach to defensive shotguns.

The advice you'll usually get on here is as follows: "If it is for fun and won't be used to protect life, do whatever makes you happy. If it is meant to save a life, we recommend a more practical solution." To us, Roadblockers are pretty much toys that have almost no uses in a defensive setting. Put a good conventional stock on it and somehow lose the junk on the muzzle (or change the barrel) and you have a good servicable defensive weapon. As above though, watch out for barrel length if you remove the brake. Stick a tape measure in the empty barrel (muzzle end) on the closed bolt to check barrel length. Check it three times to be sure it is empty before doing this. :wink:

Again, welcome. Pull up a crate and grab a cup of coffee. :D

Thanks for the replies... I do have the shotgun so other options arent really there right now. It is really more of a just for fun shotgun than a real tactical HD shotgun. I was just curisous to see if it would come off or not. Sounds like it might be a bit of a pain to take it off so I guess I will just leave it have fun with it and get something else if I really want to make a full tactical HD shotfun.

If I did want to get a more tactical HD shotgun... Would it be better if I were to just get a different barrel and stock for this gun or a whole new gun? Better in a value sence I'm sure I will get pretty similar performance characteristics either way.

Probably cheaper to get an 18.5" 500 barrel and conventional stock. But I've never stood in the way of someone wanting to buy another gun.
Havlin Sales carries 500 barrels, as does Brownells. Desert01 above might be able to help you out through Pro Patria as well.
The stock would just require you to pick out what meets your wants/needs.

you can get a short barrel from mossberg's website it is only $82
http://www.mossberg.com/products/access.asp?type=barrels&section=access

and a good stock might be $60 bucks or so. that is what i like about these shotguns, you can make them truly yours, they are so modular and have tons of after market stuff to do it.

If anybody wants to get rid of a Roadblocker muzzle brake, I might be interested. I would put it on the end of a rifled barrel.

It looks like you just need to borrow/improvise a spanner to get the locking ring off, and then the brake would unscrew.
