Quote HistoryOriginally Posted By Stan_TheGunNut: Just bought my first Daniel Defense rifle. It's a DD4RIII. First impressions is it's a nice rifle. It has ambi controls and appears solid. For the money, I think it could come with a much better trigger. The one in it isn't good at all. I would kinda expect it from other brands, but for what is touted as a high end rifle and the dollars spent, it's disappointing. I also dislike the furniture, but that's easily changed. I'm assuming one can still buy the quad rail, which is the RII? I'll have to look into getting one of those as I prefer them over Mlock. I haven't shot it yet, but am hoping for an accurate rifle. I hear the DD barrels are very good. I could probably swap you 1 for 1 for an M4A1 RIS II. I just bought a 12.5" RIS III but I can sell it to someone in here for cost if I swap with you. |

I got my 12.5" RIS III today and I'm kind of disappointed.
Basically just a longer version of the 9.5" so see my post on the previous page for the comparison (other than weight). However, the M203 hangers as arrived are not functional. The rivet and possibly the bracket they attach to are in the way. They are supposed to swing down and be parallel to each other, but they are at an angle because of interference. I had to loosen the screws just to get them to move because they were binding so much.  Attached File Attached File Attached FileI think I can fix it by filing the rivet and maybe the other part as well but this shouldn't be like this from the factory. Oh, and before the "doesn't matter if you don't have an M203" guys show up. Yes, I do and have an M203 and yes, it should work. |

Quote HistoryOriginally Posted By TGWLDR: https://www.ar15.com/forums/AR-15/DDM4A1-RIII-Initial-Impressions/118-778460/?page=1&anc=bottom#bottom OK. Looking at the one I just got. The problem is the M-LOK screws themselves. If they are protrude further out than the M-LOK nut when it is pre-set for installation, they will hit that bracket. The nut itself fits fins. Screws that are long will also hit a RIS II bottom rail if you are running one of those as well. |

I already removed the tabs, but it's nice to know it's not a big deal to drill out the rivets. I was thinking of doing it because I have no use for an M203 mount. I'm waiting for my barrel to come back so I can finish assembling the rifle.

Is the issue above only for mounting a m203 or for mounting stuff to the mlok on the end?

The bracket that is riveted in can still be in the way of M-LOK screws regardless of how long the rivets are. |

UPDATE: I spoke to DD today, and the solution they cam up with to allow use of the forward mlok slots was to completely drill out the rivets holding the bracket in place and remove it from the rail. I asked specifically not to have the bracket removed.
According to them, the only way to get it reinstalled is to send it BACK to dd and have them put it on. Anyone have any thoughts on how to proceed? Obviously I'm frustrated that this was their solution. |

I ended up just filing down my rivets so the M203 hangers will work as intended. I'm not saying that anyone else should do this or that it is OK for these to leave DD in this condition. I did scratch the inside of the bracket but it's not visible from the outside so no big deal.
I did run into a problem with the 20" GOV profile barrel. The M4A1 RIS II didn't have this problem but because of the bracket, the 12.5" RIS III does. It didn't fit over the .845" diameter part of the barrel. I got it to go on with some force but it did scratch the barrel. If someone wants to mount one of these on a rifle length gas system barrel, they may need to remove the hangers or the hangers along with the bracket.  Attached File Attached FileDD was right about the M203 capability with a mid length gas system. The barrel latch touches the bottom of the gas block but because it is such a low profile gas block, it doesn't push it in too far. I don't know if this will have a negative impact on accuracy or any effect the heat from the gas block would have on the M203. You probably won't be able to remove the barrel.  Attached File Attached FileI don't think I will be using the M203 on either of these setups. |

Got the Mk18 R3 upper today. I threw it on my lower and handled it a bit, I’ll get it set up this weekend. I think it’ll be a winner though…the rail feels awesome in hand. Perfect combo of lightweight and rugged feel to it IMO.

It feels comfortable in the hand too, especially with some Magpul low profile rail covers at the 3, 6, and 9 o'clock positions. I am very happy with my purchase. I need to find time to take it out shooting here soon though. |

I finished my 12.5" build. It came in at 8.5 pounds with the suppressor, optic, light, and BUIS but with no mag and sling. The 13.9" it replaced with a Geissele Mk8 rail was just barely under 9 pounds in the same configuration.
I'll be removing the 13.9" barrel from the other gun and configuring it for longer range shooting with an 18" SPR barrel, magnified optic, and bi-pod. |

Serious question, but what are these two screws for on either side of the handguard? I haven't been able to figure it out on mine and thought my handguard came with extra screws until I was looking at this thread again.
 The two spots where they go just seem like superfluous threaded holes that don't interface with anything, but they must be there for a reason.  Attached File |
