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? |

Originally Posted By Akin: Yeah, thanks! Anyone know if you get any useful information if you register like the site wants you to? View Quote 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. |

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. |
