Quoted: Howdy folks, Building an 11.5 SBR and I’ve already got a lower. Just looking for advice on which upper however. https://danieldefense.com/ddm4-v7s-upper-receiver-group.html https://geissele.com/super-duty-complete-upper-11-5-5-56mm-black.html End use is suppressed SBR. Opinions? $1200 for just the upper ? I would assemble it myself, with 1st tier parts. you could take a bite out of an optic with whats left. |

Agreed. You could build a badass upper for much less than that.

Colt 6933EPR 11.5" can be had sub 9 hundo if you're not up for assembling.

I’ve put together a list of nice parts, Criterion barrel, DD bolt, G rail, adjustable gas block. Comes in $100-200 less than the pre.
Not opposed to building. Done a couple and all turned out pretty good. I’ve just heard great things about G and DD. So I figured I’d ask. |

I have an 11.5 along with 4 other DD rifles. Solid equipment.
The DD will be lighter because of the MFR rail, and their barrels are fantastic. However, Geissele is a solid choice as well. Especially if it comes with a Surefire muzzle device or you like their colour options. If I were in the market for anouther AR15 rifle, a DDC Super duty would be at the top of my list. |

DD makes a damn fine barrel and rail.
G makes a damn fine barrel and rail. If you buy a complete G SD upper or rifle you get a rail that's keyed to the upper, a forged bolt, an updated cam pin made from H13, a carrier with lengthened bearing surfaces, a SF FH, and an airborne charging handle. A G SD rifle gets you updated an LPK made out of SS, a special trigger, improved recoil spring, and a buffer tube with extra drain holes. Unfortunately they cheaper out with the endplate. The DD rifle is mostly milspec with updated endplate, grip, and stock. And I'm sure I'm missing some other things as I haven't handled one in quite a while. IMO both are overpriced at their MSRP and at discounted prices the G has more features. You have to do the math for yourself. |

If you look at the tan rifle on G's website you can see it.
the trigger bow is not quite flat with a slight radius and a bit further reach. It's an excellent trigger. IMO a touch better than an SSa-E and the best non adjustable trigger I've tried. To me it an enthusiast's trigger, a touch light for "duty" work. The heavier SSA seems better suited to "duty" work. my ONLY complaint with the SD rifle is the mil spec endplate. A rifle in this price range should have some sort of QD endplate. I do think the 5 axis trigger guard is a bit much and the regular super duty trigger guard would have been just dandy. The included grip and stock aren't my cup of tea, but those things are personal preference |

Not sure how long the LaRue backlog is, if any, but their 16” 5.56mm UU kit for $750 is pretty awesomely priced and members here have posted some outstanding groups through them. I just got one of their $300 Accuracy packages (MBT-2S & 16” Stealth) and cant wait to get it out to the range... it showed up like 2-3 days after ordering.
Personally, I’d get the DD over the Super Duty because when it comes to chrome lined barrels DD and Criterion have a rich history of being at the top of the heap. DD uppers are semi-regularly on sale a handful of places <$1000 |

An adjustable gas block was mandatory to get mine to even function with a suppressor on. Figured this might be relevant since OP is looking for a suppressed SBR. FWIW, I still like the Larue and it is very accurate. |

I have no idea what size the gas port is on my 14.5 stealth, but I run a sprinco blue and H2 unsuppressed and I could probably go heavier.

I would go BCM personally, I have a 16in and 12.5in from them and the fit and finish is just phenomenal, no play between upper and lower and they are both tack drivers. I think if you factor in cost BCM is pretty hard to beat
But since that isn’t what you asked, of the 2 you mention I would go DD all day long. I think the only downside is every DD I have shot seems to be pretty over gassed but I have only shot 2 of them. They where both very accurate and 100% reliable. I think giessele is overhyped and overpriced, I just switched my 2 triggers from geissele to Larue, over half the cost and to my finger they feel better by a decent bit. I can shoot them more accurately and faster. With all the QC issues we have been seeing lately from geissele I don’t think I would ever by one. Anyway just my opinion |

Everyone is cranking and everyone is having lemons slip through the door… it’s part of the risk of buying a gun in late-Covid / early WW3 2022. Welcome. Gamble now and hope you don’t have to trust in QC, or wait for more salad days. Choose. I just got a fresh super duty that shoots great and looks even better. Ymmv |

Thats a tough question, since they both won contracts to be used for todays military. I think they are equally good equipment, and if you could get one for less, or easier then thats the way to go. I personally have never had a complete build from DD… or Geissele for that matter, but I have used a lot of their parts in a lot of my builds. I cant say I like one more than the other, but I would go Geissele.
…Or you could put both in and go do the dirty with the perfect homo-geneous blend… I think kids these days call that a tossed salad I have shot BCM a lot (actually have a complete by them), personally don’t have any issues with them either. But its not a DD or a G. The beauty is, we can debate this all day, due to there being hundreds of options to pick and choose from. All in all, if its complete, well lubed, and it works. WGAF what brand it is? |

FWIW I bought a DD Factory SBR in 2015 and its been amazing. MK18, very happy, great with my RC. I need a PRI gas buster but otherwise great.
I bought another DD in 2021 and while it was nice it didn't feel special. It shoots fine, but I think the plastic port cover on the upper combined with the lower being one of their generic lowers made it feel less special. I'm building an upper with the blend of the best parts (URG-I) and I think this will lead to my highest satisfaction; so that would be my suggestion. |

I've heard good things about both. I've put a 1000 rounds through my brothers Super Duty and I absolutely love that gun. But I plan on getting a DD upper soon so I'm on the fence about both, they both seem like great options.

Wouldnt give geissele a penny for thier shitty uppers/barrels. Build it, or buy a colt and throw a g rail on it if you must have one (as thats really the only desirable part on that upper). The DD would be a fine choice as well, if a bit overgassed, and certainly overpriced.

Late on this post, but I recently bought a Geissele 11.5” upper…Labor Day sale for a grand. Also wanted to try their braided recoil spring. Ran it today on my Colt M16A2 kitted out with the Geissele SSF SOPMOD trigger and H3 buffer. Shooting Federal XM193, the thing ran like a top…chewing up 300 rounds semi and full-auto without a hiccup. I also like the braided recoil spring…no “SPROONG”.
Fit and finish on the upper is freaking beautiful. The nano coating on the BCG made cleaning a breeze. No accuracy testing, benched just enough to zero the Aimpoint T-1, besides this is no sniper rifle…it’s a full-auto range toy. Highly recommended. |

I haven't owned them all, but I've owned a few, and GSDs are the best rifles I've ever had.
Specifically comparing the 11.5 SD vs DD Mk18, the G is lighter (this due mostly to the rail), more accurate, better gassed, and has the superior REBCG. I also like the rail being keyed to the upper so that it cannot possibly rotate. I can't name a single metric in which the DD is superior. And there is nothing wrong with the DD, it is a great milspec upper that I enjoy and shoot frequently, and trust to run very well. But if I could only have one, it would be GSD. |

Of the two you listed I would opt for the Daniel Defense. They make outstanding barrels and have a track record of making outstanding products albeit a little on the pricey side and sometimes I think overpriced. Still I would choose the DD if faced with the choices you listed.
