Mossberg 500 Road Blocker

[RandKL]

I does not work for the shotgun just like porting does not work for a shotgun.

Wrong. Muzzle brakes and ports work for *ALL* firearms in which a column of pressurized gas expels forward to propel a projectile. Divert part of the gas and you divert part of the recoil....divert that gas into a direction that counters the recoil and you can reduce recoil by a considerable amount. It can't *not* work. It's simple physics. The only question is in how efficiently it *will* work. The Vang Comp guy claims his barrel treatments (porting, backboring, and lengthening the cone) can reduce recoil by ~15%. Mossberg made a claim of 35% recoil reduction on the 835 Ulti Mag. It can't not work. It's simply a question of how much it *does* work.

Porting on a shotgun does NOTHING for recoil. It MIGHT, (emphasize might) reduce some muzzle jump, but that has nothing to do with recoil.

Lengthening the forcing will reduce peak pressure and that will aid in reducing recoil. Overboring a barrel is somewhat minimal at best, and is usually not noticeable.

If you truly want to reduce ACTUAL recoil, a heavy gun with light loads makes that happen. Reducing FELT, or perceived recoil, can be aided by using a semi-automatic action and lengthening the forcing cones a little

I'm glad you brought that up and clarified it for us, OOL. Not that anyone but you has even hinted that it might (it actually does, but to a small degree that wasn't worth pointing out), but thanks anyway lol

I have a feeling this thread is going to do a 180 pretty soon and confuse everyone. Might be a great time to go fill the coffee pot and work on some projects and just let it go.

I'd rather have one of these Road Blockers than a Taurus Judge.

Perception is reality.

If you "feel" that comp works on a shotgun, then it works.

Take that shotgun and comp to a lab and measure the effectiveness, and you'll see that It has an IMPERCEPTIBLE effect.

Muzzle brakes and ports work for *ALL* firearms in which a column of pressurized gas expels forward to propel a projectile. Divert part of the gas and you divert part of the recoil....divert that gas into a direction that counters the recoil and you can reduce recoil by a considerable amount. It can't *not* work. It's simple physics. The only question is in how efficiently it *will* work.

It absolutely works. A little. Very little.

If you like it, great. I think it's laughable.

 

[oneounceload]

Yep RandKL, you and I are not going to come to an agreement on this topic, so I'm letting it go. If you like it, go buy one.

I does not work for the shotgun just like porting does not work for a shotgun.
They are just noisemakers to the shooter.
On a 50 caliber where smaller bore diameter and whole lot more powder and pressure are concerned then yes it does work.

Sorry but that is NOT correct !!! I have porting/muzzle brakes/compinsators on almost EVERY ONE of my competition firearms ---- "Front Sight" the monthly journal of IPSC/USPSA/Action Shooting has done MANY tests on different porting/muzzle brakes/compinsators and THEY ALL WORK TO SOME DEGREE --- the best tests I've seen all have the firearm "locked" in some kind of rest and use a pendellum type recorder to record both muzzle rise and foot pounds of rearward thrust.

One little thing....
My mossy 835 with ported barrel recoils way harder than a similar gun, same length barrel, same loads with no ported barrel.

Such a difference, in fact, that I was actually really suprised how hard it was when I first shot it.

I think the Brake on the roadblocker looks ridiculous.

Ill be leaving now...

 

[Grunt]

Works or not, I'll still laugh in the face of the mall-ninja that buys one of those things.

 

[sarduy]

thanks for laughing at me, it so happen that i bought one yesterday, but it's all good, because you won't be laughing once i start shooting next to you.

btw i did't buy it beacause it's mall-ninja looking, i bought it because i like it. plus i can allways chnge the barrel

 

[highorder]

How does the brake attach? Is it simply clamped on?

 

[AcceptableUserName]

it may have a benefit I don't know, but it isn't worth the added length, especially on a pgo gun where 18.5" is pushing the usefullness as it is.

[Big Bill]

sarduy - That's ok. I think they're cool too. I guess we'll be mall ninjas together. Besides, who gives a crap what they think!

 

[highorder]

Threaded with a lockring. Cool. Easy to remove.

 

[Sam1911]

Threaded with a lockring

Yeah, sweet! That opens up the aftermarket for lots of useful threaded muzzle devices that I'd love to add to a shotgun barrel. Like ... uh. Like a ... um.


Wait, I've got it...a ...no, no... well, I'll think of something.

Maybe you could get a really cool thread protector cap to go on it. Very stealth!

You could add a buttstock, too and then you'd have a useful shotgun, but you'd still know it was a "ROAD BLOCKER" in disguise!

Kind of the best of both worlds, eh? A sleeper, if you will -- a Road Blocker all dolled up as a serious weapon!

[Gunfighter123]

I also go along with the idea of putting another stock on it --- either a full stock pistol grip or a side folder.

Precisely. You crack me up Sam.

 

[GoodKat]

The people who claim to have actually shot it say that it actually significantly reduces felt recoil, contrary to my doubts regarding a brake on such a low pressure weapon. One thing is for sure, it's better than that fake suppressor piece of crap.

 

[tkopp]

I dare you to put a side folder on it and take it to your local skeet range.

Unless they are shooting that monstrosity side by side with a PGO 500 sans muzzle weight, any perceived recoil reduction is wishful thinking for having bought into the hype, or guilt for feeling like a mall ninja.

Threaded with a lockring.

The lockring may just be a threaded insert with set screws to keep it from backing off...

The brake looks plastic to me.

I think the effectiveness of that brake simply boils down to the power of suggestion. Like the compensator bbl bushings for 1911s or a 15hp gain by installing whatever air filter on your car.

 

[Fred Fuller]

They *are* ugly, but they work

They work a lot better on a .50BMG. But if someone need or wants a full blown muzzle brake on a 12 ga. at least they have that option now. It's at least a partially free market, and that should be appreciated.

I still think it's better to get started on a basic box stock riot gun if possible, though, just as I think people still need to know how to drive straight shifts, in case they ever need to use one. Just call me an old stuck in the mud...

[The Captain]

I kinda like it. Probably wouldn't buy it.

Does it work? Who knows, but it OP like it, it's his money. The Brake is definitely not plastic, I've handled one.

I felt invincible holding it. lol

 

[Guns and more]

I have the tacitcal. The road blocker seems a bit extreme to me.
Quite frankly, I like the pistol grip (Mine has the Knoxx) and I don't care what others think.
If you think it would be fun, or useful, go for it.

what kind of scope/reddot rail works with the mossberg 500?

As far as scopes on a P/G, forget it. You'll be shooting from the hip.
As far as a rail, I got a short rail from UTG on E-Bay (just search for mossberg rail, etc.)
It is well made, uses the 4 screw holes on the top of the receiver, matches perfectly, and I mounted a LED flashlight there.
