Well, that's my question for today.


Is either platform really better? I just received a dissapator kit in 5.45 and don't know if i should build it or sell for a normal M4 type. What are the advantages..if any.

A dissipator is a 16" barrel with a carbine gas system. Where the front sight base normally is located,
the dissy has a low profile gas block. It has rifle length handguards, 12" that cover the gas block and
a front sight base is located closer to the muzzle.

The only advantage to the Dissy is the longer handguards and the looks.

Most Dissipator-style ARs also have the advantage of a longer sight radius than the M4-style (or most other) 16-inch barreled carbines. If you intend to primarily shoot iron sights, this could be considered important.

The lighter-weight barreled Dissipators aren't too bad. I have one, and I'm happy with it, even though it has a full-length FF rail handguard on it. The heavy-barreled Bushmaster Dissy upper I owned for a while felt VERY cumbersome and muzzle-heavy; one guy who shot it said "it swings like a lead pipe."

This what my current one looked like a year or so ago; it's been through a few changes since then:

Well, I think mine would be heavy barrel. There was no option.

Can't decide whether to keep it or not. But I will be mainly using Iron Sights

Crap forgot all about the longer sight radius.
The Dissy looks sooooo good!

I thought the dissapator had the full length gas system?

No, folks have tried building them with full length gas systems with less than stellar results.

The original Bushmasters have always had carbine length gas systems.

I built mine on a BCM 16" mid-length barrel. Longer sight radius, less exposed barrel to burn yourself on, and the longer handguard allows for a grip farther down the barrel (more muzzle control). What's not to like?

What's not to like?As parts for the mid-length carbines become more common, I am leaning toward the middies being a better option for 16" barrels than the Dissipator-style guns. Plus, they look more "balanced", to my eyes, at least. The stock 16" carbines always had too much barrel hanging out past the handguards; the Dissipators, too little.

Perhaps we should call Middies the Goldilocks option; they're "just right." :supergrin:

But I'll stick with my Franken-Bushy-Dissy for now. :cool:

Ya, I'm a former Bushy dissy owner who now has a BCM middy.

My BCM middy was originally going to be a Recce type build, but I got a killer deal on a Troy 13.8" rail, so now I guess it's a midlength dissipator type :dunno:

You use a low profile gas block on a carbine or mid-length gas system, and install rifle handguards on the barrel. On a 16" barrel (the length implied by the term "dissipator"), this means the handguards go almost to the end of the barrel. A front sight post is installed in the rifle-length position, but it acts only as a sight, not also as a gas block.

The "cool look" factor can not be dismissed. But also, longer sight radius, and ability to place hand farther out to stabilize off hand shots.

One of my many M4geries

And my newly built Dissipator (5.56)

Different strokes for different folks. I like having a variety of ARs in my collection.

I think the Dissapator with the fixed front sight looks silly. But that's just my opinion and we all know what they say about opinions.

Here's a picture of the Dissapator type gas system.

I think I'm gonna turn my CAR15 into a dissapator as well.
I have ALWAYS perfered the dissy look

I had an original Bushy Dissy...heavy, fluted barrel...A3 style with an Aimpoint Comp ML2 in a PRI mount.....once.....

It was heavy but, good God....was a real tack driver....sold it though due to needing the ten $100 bills being waved in my face more than I needed the weapon......oh well.

I have always liked the frankenpator.

I had a Bushy dissy also, but mine didn't have a fluted barrel. It always seemed kinda front heavy. I no
longer have mine.

Bushmaster offered it as an option....I think it was $50 more.....

It did reduce weight some....looked nice as well.

I can't say that I don't miss mine....but what I used the money for was much more valuable to me than an AR....so was well spent.

I don't like the Dissy.

I prefer a midlength or an M4 profile.

I shot the hell out of mine for many years just like this,
http://www.fototime.com/CC9061370122307/standard.jpg
Even changed out the collapser stock for the A2 stock.

When I finally got a couple M4 carbines put together, I replaced the barrel assembly and turned it into this.

It is now a basic 20" Govt. Profile 1-7 twist A2 version and still fun to shoot!

DJ, what make of riser is that on the scoped rifle you posted above? I like it.

I've got a drawer full of this type of stuff; I dig out what I need, bolt it on, and go. It might stay, it might get slapped on another weapon at some point. This one has given me no problems through many hundreds of rounds, and several multi-gun matches.

Yeah, and with everyone and their brother having a AR these days, it's nice to have something a little different. Plus Dissy's just rock.

Until you shoot the barrel out, then they kind of sputter and group like a shotgun! :supergrin:
