Bushmaster Dissipator

[Sanders]

My brother wants to sell me his Bushmaster Dissipator for $800...It looks like a 18" barrel with full length handguards on it. He's only shot it twice since he bought it brand new last year.

Is it a good deal, or is he trying to hose me?

A dissie is a 16" barrel with full length handguards, and there will be a gas block where the sight base for a 16" would normally be. People like the dissie since it gives you the full sight base.

$800 is about what one goes for new, maybe a little bit more in some areas, assuming it is the model with the collapsing stock.

Thanks. I'll probably pass. If I want a poodle popper, I'll probably build one. Building my own firearms has become addictive.

Here is my dissipator. They look funny, but I like the full-size handguards and the full-length sights.

Built on an old pre-ban PWA receiver. Colt upper, bolt, bolt carrier. Bushmaster parts in the lower. Bushmaster barrel.

The barrel on this one is a fluted. Can't see much here on the end, but there is some more under the handguards.

I really like the Bushy M4 dissipator barrel, it's like an A2 barrel that's cut off at 16". Light under the handguards, not a full heavy barrel. You still have the good gas block, full length handguards and most importantly full length sight radius.
I built on using an A1 upper, the light weight M4 dissipator barrel, a Diemaco C7A1 stock (M16A1 length using the better M16A2 materials) and an A1 pistol grip. This was my favorite CQB rifle. It shouldered fast, was about the same oal as an M4, had a much better gas system, way better iron sight's with a longer sight radius and sturdier stock with the shorter fixed A1 length stock that was much tougher than a standard A1 stock.
Damn, I wish I had held on to that one!

Here's my DISSIPATOR with a bunch of junk on it:

I've since taken everything but the HOGUE forend/grip and REDI-MAG off of it.
I wanted it to be a lightweight, functional, and portable AR15 again.
It's one gun I'd never part with...:shades:

Ahh! Dont be fooled by Bushmaster; their Dissipator is not really the full size A2 gas system. It is indeed just an M4 with a fake gas block up front. Just take the handguards off and look:eek:
If you want a dissipator I would suggest a build or pick up a DPMS upper; DPMS sells the real thing...

[K.O.A.M.]

I'd pass. You can put one together yourself less than that.

[pr4mnce007]

Don't be fooled by FAKES, either. :devil: ;)
Bushmaster is THE original Dissipator.
As far as the price goes, buy it. You'll be money ahead with the gun already put together.

The idea was to provide the shorter bbl. with full sight radius.
All the other mfg's. have done is modify the idea somewhat.
Get the 'Dissy' and be happy! :biggrin:

My dissy upper actually started as a complete Colt upper that I picked up at a gun show. Some had already cut the barrel down to 16". When tested, it short stroked. I then read up on the dissipators, and learned that the Bushy dissy had the 16" gas system hidden under the handguards. I also saw other vendors that sold barrels with the full-length gas system on 16" barrels, but I didn't know what to make of them. I suspect that they had larger gas ports? I can't say for sure. I decided to go with a Bushy barrel, fluted, that I installed on the Colt upper. And my dissy, shown in the photos, was born. http://chilirat.com/emoticons/chilirat.gif

Amen brother its the full length sight radius we want not the full gas system.

And yes you could put one together for around $600 ish on the the cheap. you could do it with a "model 1 sales" complete kit minus the lower rec. then get yourself a stripped lower from any of a host of different companies.

If you're talking about the shorty gas system under the handguard, they're the original.

If you're talking about a 16" barrel with full length handguards, they most definitely weren't the first.

I built several of them twenty years ago.
This one has an early M16 barrel so I could mount an Elbit Falcon sight. A "Dissy" gas block would have been in the way.

Of all the ones I built, I only had one that wouldn't cycle and it was made from a used mil-surp barrel that had seen a lot of use. I did open the gas port a little on some of them for reliability.

That's what I meant --- the gas system.

Cool looking rifle you have there.
