It is not obvious from the pics, but a Dissapator is a carbine gas system hidden underneath rifle lenth handguards. The FSB you see does not include a gas system.
In the pics on the above thread, you can see the FSB without any roll pins installed to hold the gas tube in place. Beyond that, the carbine gas system allows you a lot of latitude for anything you want to build. If it floats your boat, go for it. I personally can't stand the style as it looks so wrong. |

The classic method is a rifle length gas system, and some vendors still try to get away with that, but it presents problems with cycling. I don't know of anyone building a carbine gassed dissy. Best way is the way PSA or Spike's does theirs, midlength gas, trouble free and smooth as silk, longer (iron) sight radius, and more real estate on the handguard which is nice, especially if you have longer arms. |

Here's a PSA Dissipator with the hand guards removed so you can see the gas tube set up. As someone else mentioned, the gas block under the front sight post is non-functional. The "real" gas block is a lo-pro under the hand guards.

used a YHM lo profile gas block .. and wow !! like to never got it on there !!! tight !! with the screws all the way out. no gas leaks there I'm sure. then put a YHM clamp on flip up front sight .. i did use an old gas tube cut down for the handguard cap. turned out pretty nice. but im still working on the other dissipator with the rifle gas.. we'll get it going soon. |

The first AR I bought was a DPMS Dissipator with the rifle length gas system. It shoots great and has never failed me. I like it so much that I put a RRA 2 stage trigger in it and it is the gun I use when I get to go to a 3Gun Match. Its gone through a lot of different iterations, but, it is back to basic A2 stock, standard A2 forearm, and iron sights. I seem to like it best that way.

I've been trying to find out if theDelton and DPMS barrels are made by the same company. my gas port is .098 DPMS s 110 .. I've trimmed my barrel from Hbar to the thickness of a M4 cutout..handles great. its one of my favorite ARs .. |
