Just to confirm, this is the correct barrel and low profile gas block combo from Daniel Defense:

Okay, so I just got off the phone with Geissele. They told me that these days, they use the DD Mk12 gas block, but they “contour” it, so there are no clearance issues.
I asked why they don’t just use the DD low profile gas block, and he told me that it’s not in the contract, so it wouldn’t be clone correct. Once it arrives (a week after the order was placed, they still don’t have any shipping info), I’ll put my Elcan on it and use it as my patrol rifle at work. In other news, for a different build I’m about to start for another guy at work, I was able to finally get a 14.5 mid length from Daniel Defense with the low profile gas block installed. They’ve been out of stock for quite a while. We had sourced a DD mid length barrel with a Geissele nitride gas block on it from Charlies (they said it was a “new take-off”)... now we need to figure out what to do with it, since he wants the straight DD w/LPGB. Does anyone know if those are worth anything in the secondary market? |

I have seen no photographic proof of any other gas blocks being used on issued URG-Is. |

I have a clone with the mk12 and they made relief cuts to the mk12 so it now has better clearance than the G block that is on my 10.3 urg-i Ex. Regularly the bottom of the mk 12 looks like this: \___/ But mine doesn't have those two sharp corners on the bottom it has flats where those were from relief cuts |

The Geissele gas block is too big as well, IMO. The wall to the right or left of the gas tube area is where the dropped rail bent. The Geissele gas block has flanges in that area which bring it close to the rail. Quote HistoryOriginally Posted By pezboytate:

Quote HistoryOriginally Posted By Akin: Yeah, thanks! Anyone know if you get any useful information if you register like the site wants you to? Nothing special about that site. Any parts database system should yield the exact same information about that NSN. The description field listing the actual manufacturer's SKUs is part of the NSN. (Listing internal SKUs is not a requirement, this particular listing is unusually helpful) If you look up that NSN on another system you should see the exact same thing. |

I’d also point out that a few sites still show NSN 1005-01-671-3911 as including the “(2) MK12 low profile gas block, P/N: 408JXN00024, 1 EA.” However, the majority refer to “(2) PIN, GAS BLOCK, URG-I, P/N: 15-028-02227, 1 EA.” |

So, no shipping info from Geissele yet, but I guess that’s to be expected.
Once it comes in, I need to update my lighting system. I currently use a bright one but it still has an incandescent bulb. The activation switch is on the side of a vertical forward grip. What kinds of lights are they using today? I don’t seem to see many vertical forward grips any more, everyone seems to grab their barrel at the muzzle which I think looks ridiculous but who knows maybe it works better. Whatever, I’m an old dog. I might not put a vertical grip on this new rig but I’ll still need a light of some kind, it’ll be my patrol rifle at work and while not mandatory it’s sure a good idea. |
