Who is cocktailer? Is he a member here that does barrel work, Like 45Bravo? Id like a 605 upper half, preferably with a 1-9 twist, but my last Idea of getting a 604 upper half and cutting it down kind of fizzled.
How reliable are the 605s with the original gas system? Are the people doing them today opening up the port? |

Are the people doing them today opening up the port? 45Bravo does the port work on rifle length gas systems. He has figured out what size hole works. When I get around to finishing mine, I'll use a middy gas system. I had a rifle length version years ago, and it had trouble in the cold up here in MN. |

^^^^^^^^^^^^^^^^^ Interesting idea!
My 605-ish upper is a Bushmaster Dissapator 1-9 twist (sadly) heavy barrel with fluting under the handguards. The barrel was shortened the last little bit so the 3 prong flash suppressor is tight up against the FSB, and then pinned and welded to keep it a title one upper for any rifle lower. It is a lot heavier than I wanted, but over ten years ago it was the only game in town that I knew, and gave me some peace of mind for reliability. Like the NDS crew, I am in a fairly cold climate. The upper has been 100% reliable on a number of lowers, including some friend's M16 full auto lowers. |
| I tried a heavy barrel dissipator 605 setup myself a while back. It was the only barrel I could get during the post election lunacy. Way too heavy! Sold it on. Now I'm thinking M4 profile dissy from BM. The M4 profile is fairly light in weight. Should be sweet. |

Wonder how a 605 would look with a 607 collapsible stock... Don't know, but with a 629 lower and a 30 rounder they look pretty tough. http://www.megpro.com/ar/15/earlyarclone/605clone/605629.jpg Interesting rack markings. |
