I'm not doing an exact clone but can someone recommend an offset Scout mount for the Block II? I'm looking for something that will clear the 99051 front. I was looking at the Gear Sector offset mount and the IWC Thorntail SBR offset one.

Gear Sector will fit, but depending on what side you want to run the light on and how far forward, you will have to make some compromises. You can see that it just barely clears with the light on the right side and about as far forward as you can get it.

I paid around $65.00 or so a few months back. Mailed it in on Wednesday, got it back the following week on Tuesday. I sent in a Daniel Defense 16" inch .055 gas port barrel and had it turned into a 10.3" .070 as I didn't want the commercial .080 barrel DD offers.

They do this service all the time, do it right, and typically do a week turnaround. You could always buy one of the already chopped ones on the EE to save some time but the price isn't great. |

That position seems to be being used by people who really want the C-clamp grip as far out on the rail as you can. There's a number of schools teaching this now. So I think they're using the switch for white light and then using the button on top of the atpial to fire the laser under nods. They're probably using the dual switch still vs. the single because it's what's available and it mounts to the rail with no additional work. It looks goofy and wrong as hell tho.

Is there a reason why we've known otherwise to some of this for a while now, but some still claim every CQBR barrel is Colt? Don't get me wrong, I realize the vast vast vast majority are, but facts are still facts. There's a reason why some of us have "mil overrun" DD .070 ported barrels with factory pre dimpled and installed Mk12 gas blocks on them. And there's also a reason why DD continues to produce and ship those same barrels to this day, but they are unavailable to civilians... I'll also add that complete DD uppers have in fact also been purchased and fielded by SOCOM. Once again, in vast minority numbers in the grand scheme of things, but still doesn't change the facts there either. Although, similarly to the exact DD barrels being fielded, the exact DD uppers being fielded aren't available for civilian purchase either. They ship with absolutely no markings at all on the upper receiver, and would not be available for purchase for a build. I'm really not trying to stir the pot. I'm just pointing out that in this particular case, a member specifically asked if some DD stuff was in use - he was then told, no, it's all Colt (aside from upper receivers, but then no mention of the DD upper receivers in use), but that's not entirely true. And once again, we've known that to not be entirely true for a while now. I'll also add that this isn't like that small (what was it, 100 or 150?) one time run or whatever we wanna call it of LMT URGs. DD has been continuing to churn out .070 CQBR barrels and their "SOCOM" CQBR uppers to this day. And they sure aren't available or being sold to us civilians. The sole batch made available to civilians dubbed a "mil overrun" is what I call a clue... |

Anybody have experience with the Colt 6945ck's? I'm really tempted to pick one up. I've wanted a DD mk18 upper for years and always figured I'd get around to building one. Hell, I have a 10" Geissele rail sitting in the bedroom waiting... I don't think my can would clear with the 10" rail so maybe I'll pull the trigger on the Colt or DD. The Colt is actually a bit cheaper. Any input appreciated

Decided To move forward with a mk18 build even though my sopmod block II isn't quite finished. Seems there are quite a few ways to go about it. In the next day or two I'll order a Colt lower and keep my eyes open for a Gen 1 SOPMOD stock.
For the upper one of my options (lowest priced option) is to pick up a built DD MK18 upper. If I do this I'll sell the bcg and charging handle and go with Colt Items. I want to stay mostly true on this build. That being said, what do I do with the DD upper receiver??? Keep it and paint over it? Replace it with a Colt upper receiver? Thought?? |

If you don't request anything, ADCO has their own spec that they use for reliability. It's slightly larger than .070 but nowhere near the size of DD's commercial barrels. They do this for reliability so that you can operate the gun with a variety of ammo both suppressed and unsuppressed. If you specify that you want .070, they will do that for you. Just know that with the standard carbine spring / H2 buffer combo your gun will short stroke on weak ammo until the gas port erodes enough for it to handle it. It will run 100% suppressed on pretty much anything. 2. I'm not sure what you mean by "new one's have to be drilled", but all they're doing is simply opening up the existing gas port to a larger diameter (just like Crane does). |

Right now the DD RIS IIs are demanding a ridiculous premium, at least from what I've seen posted in the EE recently. If you've already got the Geissele Rail, I'd just toss a 10.5" Barrel on it and be done. It will still be an awesome build. OR you could try to use it as trade fodder against a complete upper or RISII (if you're going BlockII) I'm slowly becoming a G snob. Its started with a G2S trigger.... then I found a Mk3 Mod1 rail for a build I'm working on, and now I'm looking into a scope mount, and would probably go all in on a receiver if they get into them.
Good Luck!! |

So with the below being said; If I use a DD MK18 commercial barrel and its ris II rail a suppressor will not fit?

Good Luck!! No. the 10.3" Barrel and RISII WILL work, depending on your suppressor...For example, if you are going true clone, you're looking at using either a Surefire 4 prong hider/ 3 prong hider ( I know, not correct) and a Surefire Socom RC Can, OR you will be using a knight Armament NT4QDSS suppressor and mount. These will work with a 10.3" barre and RISII. If you were to use a standard A2 hider and a Gemtech Halo, it would NOT work. I think that an Advanced Armament 51T Hider will also house the suppressor with JUST enough clearance, but I'm not sure the 51T Muzzle brake provides enough. ARRyan should be able to weigh in on this as I think he has 57 Advanced armament suppressors layign around.
What I said would not work is the Geissele 10" Rail and 10.3" w/ suppressor. You would need the 10.5" if you built a rifle using the Geissele rail. Edit: 10.3" Barrel + DD RISII + Correct suppressor = Good to go 10.5" Barrel + Geissele 10" Rail + Suppressor = Good to go 10.5" Barrel + DD RIS II + Suppressor = good to go |

Thank you sir! Then all good as I'd use a 3/4 prong and a SureFire can.

The more important question will be how reliable it is. You're starting with an overgassed barrel and suppressing it. You're most likely going to need to do some work to the spring/buffer combo to tame that down and/or shoot under powered ammo if you want 100% reliability. I had heard enough reports of this, even acknowledged by DD themselves but didn't give it too much credit until I experienced it myself. If your plan is to run a can often I would highly recommend not going this route. |

Thanks for the additional input. I think I will follow your advice and NOT purchase the MK18 upper. I've got to keep an eye out now for a MK18 RIS II. Anynody know of one please let me know.
I think I'll follow the advice of purchasing a complete LE6920 or m4A1 if I can get lucky enough to find one. Is the Colt OEM 2 6920 a good starting point? On a superduper cool note; I did just find and purchase a painted and beat up GEN 1 B5 sopmod Stock! Quote HistoryOriginally Posted By TinyCrumb:
