I didn't know what it was until you posted this thread and pictures.

I am developing strong feelings towards you.

Up until last Fall my AR world was complete with just two AR carbines (my 2 is 1 gun policy). Then daughter #1 comes home and claims one of them for herself. Dang I says...that means I need to build myself another AR.

And I have not one but two stripped lowers waiting. So I am buying parts for two builds for this year. So I have pretty much made up my mind what they are going to be but then you come along with a thread like this for a variation I never heard of.

There are names for people like you.

Enabler.

The only rational course of action is too buy some more stripped lowers.

I love your projects and pictures. Just wish my bank account could afford some more love.

Dissipator? Is that a fancy name for a urinal? We had some of those in gym at my prep school but called them something else.

WestKentucky, what you want is similar to what is called a Kino.

I like @WestKentucky 's "Pissy Dissy" better

Where did the term "Dissapator" originate from?

When one comes into use, unruly crowds tend to dissipate.

Yeah, dang glasses. I like scopes. And shotguns, if I can see it, it's done! So sixty yards is the unaided limit.

Just a quick pic. Off to work. deadeye

I have one, a Bushmaster.

I bought it during the 1994 AWB, and it came without a threaded barrel or bayonet lug.

After the ban I had the muzzle threaded and installed an A2 flash suppressor. It has a set of XS tritium sights, but other than that it is as it came from the factory.

I have had numerous other ARs come and go, but this one keeps hanging in there. Very accurate with open sights, and probably shot more than all the others.

(Too lazy to post a pic right now, I spent the morning installing a Timney trigger in a Remington 721, and it is now time for lunch.)

More retro style

Why not just buy a carbine length gas system barrel and use a FF forend to which you can mount a sight? Or same with a constant size barrel to which you can drill a slight recess and setscrew attach the a2 style front sight tower (with locktite)?

I don't like rails, and am planning to do an A2 upper, keeping the weight around 6-6.5lbs. That anderson barrel you posted looks like its .750 to the end, which would work great, I have never seen one without a drop after the gas port area, thanks

Now that is slick. Wonder how it would look with a 3-prong flash hider on there.

That's all I had lying around...but yes the 3 prong on order, this will give it the 605 look

I don't have a dissipator. One of the reasons is that I've read that tuning the gas can be difficult (on a true dissy). Have any of you had reliability issues regarding getting enough gas? Did you need to increase the gas port size?

If I run cheap ammo in my rifle gas system it will sometimes short stroke. But with good 556 ammo it runs great. Most trouble is when you go with a collapsible stock with a rifle gas system. If I remember right, you need to open the gas port to .011.

Interesting. I had heard that rifle buffers and carbine buffers were designed to run off the same amount of gas, although with under-loaded cheap ammo in a dissipater action, you're probably taking things to the extreme

I'm waiting on one of you to show me a 20" barreled dissapator. Rifle gas with a FSB at the muzzle. Probably going to need some custom handguards made.

It could be the perfect answer for people with old eyes that still want to see the front sight. Or it could be the answer to a question that no one wants to be a witness of.

My dissipator runs 100% thanks to windham weaponry it may not be a true dissipator using a rifle length gas system, but I wanted the look and reliability of a 605 clone

Finally got off my lazy butt and took a picture:
