New RIII (Page 1 of 7)

| So Joe, what can you tell us about the new handguard? |

I was hoping DD would follow the newer trend of having the handguard run the length of the barrel, almost flush with the muzzle device. I was never a fan of how much of the barrel was exposed on an old 12.25" RIS II with a 14.5" barrel. It always looked much better with a 13.7" or 13.9" barrel, imo. Ideally, I would have liked a 13" length for 13.9" barrels and a 13.5" length for 14.5" barrels. Also, 16" barrels are still super popular and DD is leaving those out in the cold with no 15" handguard. |

That doesn't tell you the exact difference unless all of the other parts are identical. A few ounces is all I would expect though. |

Not any time soon going by their catalog at least. |

Personally, think they should have skip the 10.5” rail and went with a 15” rail that covered the 16” mid length barrel better like the V7 line is. I would love to see a 12” FSP version.. when I think of the RIS II I tend to think of the FSP version. Doubt it will sell very well though. Wait and see what lengths they offer down the road. |

They are obviously making a 10.5" to duplicate the 11.5" URG-I. I agree with the previous posters that a 13.9" or whatever would be better for the M4A1. However, people would complain that it's too heavy. And I like that the 12.6" RIII will be compatible with rifle length FSBs (even if I'm the only person that will use it for that purpose). As far as a 15.4" version for 16" barrels. I would like that but I doubt it will happen. |

9.5" for 10.3" barrels 10.5" for 11.5" barrels 12.5" for 14.5" barrels as well as anything with a rifle length gas system like a MK12 EXACT same bolt up plate and barrel nut RIS II Lower Rails (M1913) can be installed on RIS III body if you want to. M203 Compatible just like legacy RIS II Handguards. M320 Compatibility w/ our adaptors (MIL only at this point) Only available on complete rifles for starters but will be sold separately later on in the year. All Lengths. Black and Brown. S/F Joe |

S/F Joe Thanks. I'm assuming they fit over the Mk12 gas block? |

Looks like I've gotta eat crow for a comment that I made in the other topic from last summer: Originally Posted By VigilantPanda15: From a commercial market perspective: Considering that DD pretty much doesn't sell any rails that use 6-bolt attachment systems anymore (other than the RIS II), I imagine it'd be kinda hard for them to justify putting it into production for the civilian market when they've already got the MFR series as their flagship M-LOK rails.

Also, 16" barrels are still super popular and DD is leaving those out in the cold with no 15" handguard. As much as I like the look of Geissele's 13.5" MK16 rails, I've never minded that the M4A1 RIS II doesn't go to the end of the barrel - and it's not really rail space that I've ever needed, anyway. (I guess that a longer sight picture with a front sight would be nice, but it's not essential when it's already a full 12" away from the optic, and I also wouldn't run a vert grip or AFG that far out.) I think that if DD had gone with a longer M4A1 RIS III, it would have undermined the design goal of maximizing commonality of parts/dimensions with the RIS II - especially if they're hoping to pursue military contracts. Agree that this shouldn't have deterred them from offering a 15" version for the 16" DD4, though. |

Originally Posted By Marler5811: Originally Posted By BNW: Thanks It is possible that the spec will be updated to a Mid-Length. Could you verify if an M203 will fit with a mid length gas system and your low profile pinned gas block? My mock up looks like the barrel retaining latch will be touching the bottom of the gas block, but should still work. Not sure about the hangers in the RIII or any other interference. Same for the M320 with your adapters. |

Same for the M320 with your adapters. Our engineers says it works perfectly fine. |

Also, 16" barrels are still super popular and DD is leaving those out in the cold with no 15" handguard. Civilians buying these is just an extra. These are most certainly being made for sof and are going to be lengths for the barrels they use. |

You're welcome! S/F Joe Thank you to the whole of DD for making this change! Any chance some of these will be available pinned and welded or will they all be sold as factory SBRs? |
