Actually it is a Rock River lower half and a Bushmaster Dissiapator upper half but you get the picture. It looks and basically is the same rifle as the regular Bushmaster Dissipator.

I am posting this as a sort of a heads up slash warning about the Dissiapator uppers. I was not able to handle one before I bought so I was going on looks alone. I wanted an A-2 carbine with a mid-length handgaurd and a 16" bbl. When I saw the Dissipator online, I knew it was what I was really after. Some people have reported the they are muzzle heavy. I ignored this as I thought they were just used to the M-4 with thin bbl and they were talking about the extra weight of the full length handgaurds. It turns out that it is not only muzzle heavy but it is just plain old heavy. :) It probably weighs close to the same weight as a 20" bbl A-2. If you are looking for a light handy carbine, this may not be what you want. There are plenty of lighter AR-15s out there!

The good news is this, I love the feel of the 20" A-2 and this Dissipator feels a lot like it but with a shorter bbl. It is not super light but it is short and handy. It is still a little lighter than my SAR-1 that I just traded. It is about the same size as the SAR-1 also.

For me, this is the perfect AR-15. I don't want anything more or less out of an AR-15. I like the fact that it is short and I like the fact that it has some weight to it. I shot heavier guns better from a standing position better than light guns. In fact, I shoot heavy guns better than light guns period. I still would not call this a heavy gun but it is no feather.
 
it is the heavy bbl dissy not the M4 profile dissy right? I have a heavy bbl dissy and it is heavier than my 20 inch gov profile bbl

:rolleyes:
Bushmaster Dissipator "pre-ban".
With accessories...

I like 'em, too! :D
 
Heavy barrel + full-length handguards = heavy rifle.:D

The difference in weight between a 16" HBAR and a 20" isn't much, at least according to this famous site:

http://groups.msn.com/TheMarylandAR15ShootersSite/weightinformation.msnw

A Dissy HBAR is ~3 pounds. A 20" HBAR is 3.5 pounds, and the A2 medium profile 20" weighs in at only 2.5 pounds.

Really, though, a heavy rifle is not necessarily a bad thing if you're strong enough. I'm not a very strong guy at all (think scrawny Asian guy ;) ), so it's a Superlight for me... :)
 
BusMaster007,
Nice Dissy. How do you like the free float handgaurd? Does it get hot?

I was surprised by the heavy weight of the upper but now that I have gotten used to it, I like it better than if it was lighter. I just wasn't expecting it to be as heavy as my 20" SP1.:eek: I am actually happier with it then if I had got what I thought I was getting.:D I thought I was getting a thinner, lighter bbl with full length handgaurds but what I got was basically a 16" bull bbl carbine. Not a bad idea in its own right. All the accuracy of the standard 20" but with a shorter bbl.
 
Glad you like yours... But if anybody ever wants to put their AR on a diet, no better place to send your upper than Kurt's Kustom Firearms

Since you like the heft, I'd also suggest the "turned and fluted" option. It's heavier and stiffer than an M4, but still lighter than a full HBAR.
 
Onslaught,
Thanks for the tip. The thought had crossed my mind at first but the heft is really growing on me. I consider the Dissipator the Bulldog of the rifle world.:D It reminds of me of a snubbie somehow. Short, fat and heavy, just like a good Bulldog.:D
 
I always liked the Dissipator ... would have got one if I didn't get my RRA.


I've always thought a Dissipator with a set of old style M16/M16A1 triangular fore grips would be cool. :D
 
Honestly, I'm not totally happy with the Hogue forend.
It does get 'hot & squishy' :) but it also starts to unscrew itself from the torque.
I should've left the 'DISSIPATOR' handguards on! DUH. :rolleyes:

I'll be putting it back together like that soon.
I may try the Phantom suppressor vs. the Vortex that's on it now.
Trying to get rid of the 'tangs' that way.

Other than that, I love this rifle.
 
Abanian,
Thanks for the objective report on your new rifle. These are the kinds of things that help the rest of us. There's too much "woo hoo, gosh dang, my new rifle is the greatest in every way" talk going on these days. We appreciate the info.

Good call, I just sold my Colt MT-6700 and picked up a new Dissy.....like you, it was the one I'd always wanted but fell into one hell of a deal on the Colt.
It's every bit as accurate, but I have got to do something about the muzzle flash.....anything but a bright and sunny day and I'm practically blind after putting some XM-193 down range.
 
Bushy will sell you a complete dissy upper with M4 barrel

you just have to ask them for it.

They assembled one for me and is what I have on my A1 length Cav. Arms Mk I lower.

Sure it's not the absolute lightest thing to shoot, but it sure is lot of fun, especially when topped with an EOTech.
 
I like the looks of the Dissy, but after handling one I opted for my 16" HBAR Bushy Shorty. I thought the Dissy was a little nose heavy, where as I find my Shorty perfectly balanced. The real advantage of the Dissy is the sight radius, same as the 20" AR. But I bought my Shorty for short range anyway, so it didn't affect my choice.

Regardless all excellent rifles.
 
Dissy vs M4gery bb:l

I vote dissy....the m4gerys tend to balance right at the magwell, and as a result, they're very muzzle flippy, even with a muzzle brake. The dissy balances forward of the magwell. While this doesn't make for as quick a handling rifle, it's plenty quick, and the followup shot, which is pretty much obligatory for the .223, is gonna be WAY faster.


But then again, that's me, and I'm used to lugging my m1a around, so the dissy feels like a feather when I pick it up.
 
i really like my dissipator, sent it to ADCO, much lighter, also went with middy gas... ''sweet''



hoo-rah !!!

dissys RULE !!!

Heavy is always better for shooting, lighter is always better for carrying. Finding that happy medium is why there are so many variations.
