DAMN IT if I had any money I would pick one of these up.

I have always wanted a Dissy.

They look SOOOOOO nasty.

The thing I like about it, is that it's a real dissy... no extra gas block - and all the benefits of the rifle length system in a smaller package

building up a sick gun for iron sights only and I'm really exited to see how it turns out

we'll need a build thread and then a range report. with pictures of course.

On a bushmaster dissipator, the "extra" gas block is in the traditional location for a 16" barrel so there is ample barrel behind the bullet for gas expansion. That said, seems the dpms diss. barrels seem to work ok for most folks.

DPMS

Be sad face all ya want. The 2 DPMS barrels I've had were good to go, as accurate, or more accurate as I was, they were a nice fit in the upper, and a nice fit in the gasblock, I never had one problem that I could say was the barrel.

I do believe Bushmaster coined the term "Dissipator". With that said, a "real" Dissy will be all Bushmaster with a heavy barrel, carbine gas system, and a full length handguard. The gas port would have to be opened up pretty big for that DPMS barrel to run correctly.

Feel free to correct me.

Here's my Dissy that I built using a Bushmaster HB, Colt FA BCG, Geissele trigger, Knights RAS that I had to clearance for the gas block, and a Larue mount bipod. She's a sweet sweet shooter.

DPMS

Plus not chrome-lined.

You can tell what DPMS is trying to do to the noobs, too - they tout "chrome moly" like it's something special, and try to conflate this vs chrome-lined.

An 18" SPR bbl can work very well with the gas tap in the rifle FS/GB position... but carbines, um... not so well. Gas tap way up front, not always enough barrel in front for dwell time, therefore the gas flow has to be opened up, very "sturdy" and abrupt cycling. Weaker ammo can be sporadic on cycling.

That's the reason why Bushy put the gas tap behind the sight block.

The only downside to the Bushmaster is the carbine gas system.

Normal at the time of development, but we can do better these days.

CMMG has one that actually has a proper midlength gas system using a micro gas block. I believe they make a HBAR version so it's essentially an improved version of the Bushmaster.

True, however there is nothing wrong with this setup for the typical Joe Schmo. Colt seems to think it's ok with their 6920.

I can't wait to see what BCM is going to come up with when they do decide to make one.

You may correct about ther entemology (sp?) Of "dissipator"
This dpms is closer to the original version of vietname (but with an enlarged gas port to allow for reliable cycling) i have shot a rifle with this barrel before so i know it works

Sweet looking rifle you have there! I will certainly be posting a build thread with lots of quality phots. Expect the range report on tuesday!

bwiese:
I already have an AR with a chrome lined carbine barrel - this particular setup will be used to get me out to the range with iron sights only and having fun with a low recoil, fun looking rifle that doesn't break the bank
