If you don't mind destroying your delta ring, it's not too hard. You can just cut it off with a Dremel tool[;)] If you ever need to put one back on, then go through the trouble of removing the barrel.

The #58 is for mid-length gas systems.
The #58-MOD will work for your M4. |

Its not hard at all to cut off the Delta ring, and the front handguard cap. Just have to be aware of what your doing so as to not hit the barrel, receiver, or gas tube. Wont take more than a few minutes. After that, installing the SIR itself is a piece of cake.

The only "military" SIR system I've handled was the ones received and mounted by one of the Ranger units a couple of years ago and it was the C-version. There is no advantage I'm aware of in the M-version. I had one of these on my personal M4 for quite a while -- long enough to know it wasn't helping me at all because I don't need to mount all that "stuff" that the young soldiers do. The only special tool you need too install the C-version is a penny.

Wow! Never thought that "removing" actually meant cutting off the delta ring. In this case, I think I'm better off with the commercial version SIR.
How about the Knight's URX? Is it out yet? Is there somewhere I can read about it? Thanks and happy holidays :) |

You don't have to cut the delta ring off, but that's the only way to get it off w/o removing the barrel. Most people have the tools to cut it off, but not the tools to remove & reinstall the barrel.
I don't think the URX is available yet. Do a search here though and you should turn up plenty of threads on it. |

I don't like to be mis quoted, so for anyones info. I said the military have some in service.
From what little I and others have heard, they, they are performing very well. There have been some pic's of them in civi clothed gentlemen guarding the new pres. of Afganistan. With time there will no doubt be more as they are released. Someone on here also just showed Philipino SF with SIR's. You have another gentelman on here saying he saw them with Rangers. So there is no question that they are out there in service. Good shootin, Jack |

FWIW, if I had to mine over again I would have used the civilian model. Less a pain in the butt is my opinion.

I installed the #58 on this Armalite SOF(mid length)and love it. The Delta ring etc. was easily cut off by me with a great degree of care using a hack saw blade cut in half and held in my hand for better control.

I prefer the M versions (#50 here)to as they are more stream lined, don't have a useless delta ring sticking out, couple of oz of wt. gone.
Good shootin, Jack |

I'll also chime in for the C version! I really like the SIR 58-MOD but I'm taking a wait and see approach and hopefully a C version will come which will allow the delta ring and handguard cap to remain intact.
ARMS could also release an add-on forend/handguard for the SIR 46/50 that will give it the extra real estate like the 58-MOD[:D]... I currently only have one AR, I'll be getting my second one in 2004, so being versitile is important to me. I don't want to be stuck with certain system and be unable to easily upgrade or change my config when something better comes down the pipe. Just my 2 cents... |

Like Yojimbo, I think I will stick with the C version. I don't want to cut the delta ring on my very first M4. Maybe on the next one....
By the way, green18, is that a Thermold mag you have? How does it perform? Is it good? I've also read that they don't take heat as much as the Israel Orlites. What's your experience with them? Thanks. |

The Thurmolds work well, but it has been reported that in prolonged storage near heat they tend to expand and may not feed.
