Ya meen like cutting a 20" back to 16" and using rifle gas system? It's been done. Just drill the hole to .110.

I figured someone else had already done it, which makes this the perfect place to ask. Thanks for the answer.

Aren't we talking about the Dissipator?
I'm not a dissy expert, but I thought it was a carbine length (16"er) barrel with a rifle gas length. No?  Bushmaster Dissipator  |

I don't think so. I am 99% sure that there is a gas block underneath those handguards and the Front Sight Base does not function as a standard gas block...

depends on the model, the Dissapointer uses a carbine gas system, other makers (Fulton Millenium?) just chop the barrel and open the port.
a 20" cut to 16" will run with some mofication to the gas port (a lighter carrier helps too) but there is NO slack left in the system so soft ammo or low temps can cause malfs. it's been done since the first AR came out and it's never worked well enough to go widespread. |

I'm sure the Bushmaster has a carbine gas block under the HGs, just look at their barrel page, it shows a bare barrel. I am pretty sure DPMS uses a rifle length gas system though, but not certain. I have no idea about other manufacturers.

 Bushmaster Oly's K7 Eliminator has the same thing. |

Visual Comparison of the various gas system lenghts.
I don't recommend 16" barrels with the rifle length gas system. You are just on the edge of good function. 16.5" is better and 17" is considerably better if you are going to shorten a rifle barrel. Of course I can do shorten and thread jobs and I open up the gas port as required. |

That's the Bushy picture I was thinking of!
Thanks. |
