My first one was rifle gas. It never ran right in cold weather so I switched to mid-gas.

"A gun, like any other source of power, is a force for good or evil, being neither in itself, but dependent upon those who possess it." |
To call anything "Mock" or "True" at this point is an exercise in silliness.
The Colt 605 concept was a cut-down 20" barrel with a full-length gas system from 1965. Brownells now makes new clones of them. A Bushmaster Dissipator was a 16" barrel carbine with a carbine length gas block under the handguards. It was a term used in their catalog. I owned a pre-ban factory upper in 99. The only "Dissipators" I know Colt made were carbine-length gas systems for the CHP in 2002. It's now just a term. Just like kleenex, or xerox. I like my Spike's Tactical upper with midlength gas system. It's just as much a Dissipator as my first Bushmaster. Best, JBR |

My version of a "Product Improvement Program" Model 605.
No, it's not a "true" 605 in that it doesn't have a rifle length gas system. It does have what I thought a modernized 605 would have, including a KAC 3-prong suppressor mount instead of an original 3-prong FH on a 15" bbl, KAC rail, A1 removable carry handle w/true slickside upper, upgraded A1-style PG and upgraded A1 stock w/integral QD socket. Attached File Attached File Attached File Attached File Color is Cerakote Federal Standard Field Drab. I liked the crossed cannons and "U.S. Rifle"-marked LRB lower. It's really a handy little rifle. |

I'm in the process of piecing together a dissipator-ish rifle, however, I'm stuck. If possible, I need a measurement for the distance between the forward face of the upper receiver and the rear face of the front sight gas block. Or, the distance from the front rim of the barrel extension to the machined lip the handguard cap touches. I've found stated measurements 12.0, 12.7 and 12.75, but without an actual rifle upper to measure, I'm reluctant to pin anything. Thanks.

So im looking at putting a dissy together. I have a matching Windham Bushmaster reciever set and a Spikes chf 18" govt profile barrel. Would cutting this to 16" and adding taper pin cuts for an A2 post be acceptable?
Thanks. |

Yeah, the BRN-10/Proto handguards are slim and lightweight. Very comfortable.
And they have heat shields now also. |

These are the Nodak HGs. I see they have the heat shields now. But I will say, after a CMP match, I never have noticed them getting warm. I can't speak for doing a full-auto mag dump or anything. :) They have held up well the last bunch of years. I just ordered a set of the mid-length Proto HGs to make a faux mid prototype.
