New RIII (Page 5 of 7)

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. |

Can't never could 'til try came along.

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 File I 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. |

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. |

I just brought this up with Engineering so we'll figure out what needs to be do to correct this. Thank you for letting us know. |

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 File DD 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 File I don't think I will be using the M203 on either of these setups. |

Man. I am so disappointed in the execution of these rails. |

I'm almost done building out my 12.5". https://i.imgur.com/rYJTDAw.jpg I haven't put a lot of ammo through it so far (only about 70 rounds}, but it sounds great and is a nice step up from my R9. I'm very happy with it and did not get gassed out. I bet the L version is going to be sweet, especially on a 308. I only put about 20 rounds through my 308 with with the regular 30, but it still sounds great. Originally Posted By FailureToFun: Finally got my optic mounted on the rifle.

I'm looking to do something similar and was thinking the Xeno may be the solution. I appreciate the response!! |

I think it'll be a winner though the rail feels awesome in hand. Perfect combo of lightweight and rugged feel to it IMO. My thoughts exactly. 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 |

I bought a complete M4A1 rifle with the RIII. But I have a spare RISII now and wanted to see how short I could go. |
