Hey all. Just wanting to know what people think of this rail system that are using it.
Wanting a new free float rail and I really don't need all the mounting rails and need some honest feedback. Thanks~

I like it. It comes standard on the DDM4V7 rifle. I put the MFR 12.0 on my carbine build to replace a quad rail. I completely agree with your views about unnecessary rail slots and having a more slim, streamlined look, putting the rails only where needed. I run mine slick on the sides and only two rails, back-to-back in a row on the bottom for accessories.
I wanted a modular rail. I am not a KeyMod fan (don't like all those excessive holes and slots), so this is what appeals to me. Another feature you will not see on many rails is that its mounting slots also let you put the mini-rails at a 45 degree offset, if you want to run offset slights or a light and don't have to buy anything extra. Some here contend that the L-shaped hex screw mounts are fragile. That has not been my experience. They are plenty solid unless you get ham fisted with the hex wrench. I've been running mine about two years and have not encountered any problems with putting on the mini-rails or removing them. Some also contend that the design generates too much heat for rapid fire. My response to that is that the sturdy construction means fewer holes and slots. It is going to be slower to heat up, but yes, it may eventually get hotter over time. That is what a glove on the support hand is for. I really don't do mag dumps and would rather have a tendency to get hot compared to having a lot of big air flow holes that probably structurally weaken the rail. It is stout. It uses a very strong mounting system with a proprietary barrel nut and, if I recall correctly, the mounting screws that attach the rear of the rail to the barrel nut have nylon coating, which acts like tread lock. I have no shift. Also, the rear of the rail has anti-rotation tabs which keep the rail correctly positioned, even if a screw should loosen, and which help with alignment when you initially install it. As with all free float rails, I do recommend that you use a carry handle or a one piece scope mount, temporarily bridged between the top of the receiver and the rail during the install, as it will allow you to precisely position the rail for perfect alignment before you pull those mounting screws up completely tight. If you like the look, and I do, and like the durability, quality control and strength of Daniel Defense, you will like this rail. |

A couple photos. First one is set up with my scope in LaRue QD mount and with a Harris bipod in place. Second one is with the scope swapped out for an ADM QD mounted red dot and with an EoTech/Insight weapon light under the rail with a pressure switch activation in a vertical grip. Easy to move from one configuration to another.
Sorry for the poor cell cam photos.

I don't like cause it gets hot, but has no rail covers and DD has come out with their own Keymod which tells me that they are no longer confident in the MFR. No direct attachment, and the picatinny rails are a pain to get off an on. It is heavier then it looks as well, and is best used on a bench gun imo.YMMV. |

So many better, lighter, stronger, and/or cheaper options these days. Check out any of the MI SS, Centurion CMR, Noveske NSR, BCM KMR, SLR rifleworks....etc. Probably not a bad rail. DD doesn't make junk. But there are so many choices. And your personal experience with the MFR would be . . .? Tell us which rails are stronger, and how you reached that conclusion? By what means do you judge strength, or define "better"? Yes, you can find cheaper, if that is the goal, and probably sacrifice strength, precision of the tube and rail maching, fit and finish. How many of the others have 45 degree offset capability built into the slot system? That was a clear plus for me, one of the "better" factors, compared to other rails I was considering. It might weigh an ounce or two more than the lightweights, but is still lighter than many, especially after they put on rail covers to cover up the unused slots, but the extra ounce or two translates into a more rigid and strong rail system. Tube thickness is .150" of 6061-T6. Very strong. |

It never really took off with the modular rail fans because it was 2yrs late to the game, and essentially outdated when it was released. Pretty much any of the rails I mentioned have a superior mounting system in my opinion except maybe the M.I. If DD had released this rail 3-4oz lighter with more accessories/support, and the mounting system of their "lite rail", they may have had a winner. But as it stands they have a heavy pig as far as modular rails go, and not many people use them because of those reasons, relatively speaking of course. And it looks like ass. (sorry, lol....I know that is definitely an opinion, but some are vain like me. YMMV.) |

(sorry, lol....I know that is definitely an opinion, but some are vain like me. YMMV.) I totally agree and I am a HUGE DD fan. I finally got rid of my last original Lite rail for another Lite rail 3. DD kept slowly falling behind but I love the Lite rail 3 and new keymod. The MFR is just too archaic compared to what's out there now. Not as user friendly to set up, heavy in comparison, expensive for the tech involved, and I also agree about the looks being sub par if that matters. For that style rail I would take a good look at the ALG EMR. Very nice rail and it is lighter, cheaper, more user friendly, and looks better IMO. Also comes in M-LOK if you would like. |

(sorry, lol....I know that is definitely an opinion, but some are vain like me. YMMV.) So I conclude: 1. You have never actually owned an MFR. 2. You have no facts establishing that other rails exceed the strength of the thick .150" 6061 T6 tubing. 3. You criticize the rather big (I think it is 2" long), strong and secure solid steel barrel nut insert, part of the weight issue that adds to its strength and rigidity, as somehow being less secure than other DD mounting systems, without actual first hand knowledge about how it works. No offense intended, but my objective questions were answered with subjective observations. That's o.k. What it boils down to is that some guys are attracted to rails like a beauty contest preference for blondes over brunettes or redheads sort of thing. That's o.k. Just say so. Or they like change and are attracted to Keymod. That's fine and a good reason, albeit subjective. My frustration with Keymod is that you do have to buy separate accessories for it, including either separate mini-rails or offset accessories that are Keymod specific and will not work with anything else once Keymod fades away (and it will) for some other latest and greatest. The slight weight penalty is in the strength and that is a plus for me. The only criticism I've heard that makes some sense and not subjective, is the trouble that Hydra-shokz has had with the L shaped rail screws. I can understand and relate to that. I want reliability. I insist on it and will not tolerate any firearm that is not. All I can say is that I have not had similar problems. I don't doubt for one minute that he did. Maybe a few bad mini-rail sections got out? DD is a good company, I would argue a great company with a stellar reputation, and I'm sure they would make good. Change that produces a superior product is good. Change for the sake of change or to chase others, being a follower, . . . maybe not. Maybe KeyMod is now on the way out because the newest, latest, greatest may be Magpul's open source M-Lok system. Is DD too late again, or maybe we should stop chasing fads, because there will always be something newer and supposedly better. Oh, but on inspection those M-Lok slots sure look a lot like the ones on the MFR and the attachment mechanism is not very much different. Humm . . . Maybe it's just a beauty contest after all. If you are looking for ultralight or are addicted to KeyMod, then this is not the rail for you. If you want strong, slim, smooth, solid mounting and versatile (including the 45 degree offset capability with no extra cost), and put functionality ahead of trends, perhaps this will make sense to you. It did for me. |

Yes MS556,
I am well aware if you chose to purchase it then it must be the best. 1. Have not, and WOULDN'T own one. 2. If the mounting system is so good why did DD not use it on their other products? 3. If it was so good as it is, why didn't DD simply add keymod cuts, rather than spend megabucks redesigning a new keymod rail? 4. If it was that good why do so many people not choose it? 5. Are you saying the MFR is better than the KMR, NSR, or SLR rails? I said those choices were better and you adamantly said they weren't....so...? I don't have to own one to know that there are better out there. I have just as much first hand knowledge with this rail as you do the Revolution scopes, yet you still have your opinions. Based on the responses in this thread I would say I'm in the majority. P.S. Your scope is sitting about 4 miles over your upper. Cool. ETA: Please understand I'm not knocking or doubting the strength and quality, as with any DD product I'm sure it is top-notch. Weight is a primary concern of mine as well as many other modular rail users. That and that it isn't offered in more lengths would seal the no-deal for me personally. |

I like the mfr. I have had the chance to use one on a friend's ar several times. It's a quality piece. Decided to use for my next build. I guess much of it comes down to preference. The mounting system on the MFR is questionable. On a positive note, DD replaced mine with a LITE rail. If it wasn't for the mounting system, I'd really like it. |

Have you guys looked at Bill Geissele's take on a 13" M-Lok? Here. and here.
Eerily similar to the MFR, including that big steel barrel nut, although with much larger screws, has elongated slots, like MFR, albeit a different size to M-Lok specs to avoid DD patent/copyright, and has no keymod slots or huge removal of metal to weaken the rail. Oh, has 45 degree offset slots, too. And he seems not so concerned about chasing ultralight craze, coming in at 13.3 ounces or so with the strong barrel nut. I do like the larger mounting screws, although the MFR method is very strong. Perhaps DD did not use it on other rails because of its weight? I prefer strength. Looks like Bill must have thought the MFR to be a good model to adapt to M-Lok specs. DD and Geissele. Both top notch companies with similar design criteria for a strong, slim, no nonsense modular rail. Y'all gonna jump on Geissele too? I guess his looses the beauty contest, too. And has the level of debate now lowered itself to criticizing LaRue LT-135 scope mounting height to clear a folded rear sight? |

And has the level of debate now lowered itself to criticizing LaRue LT-135 scope mounting height to clear a folded rear sight? First of all if I was in the market for a heavy, strong rail I would buy YHM for $100 or so cheaper than the MFR. Secondly the LT-135 was designed to clear IR/laser setups, but if you use it for your purposes, that's great too. Thirdly, we/I aren't necessarily saying it's bad. What I'm saying is in my opinion there are better, lighter options for less or close to same money. And last of all, are you seriously claiming that Bill Geiselle modeled his successful rails off of one of DD's mediocre ones? Damn man, just cause you own it don't mean it doesn't have faults. We all have opinions, and it's good to have honest debate. I truly believe it works well for you and others. That's good. Does that mean others opinions are bogus? Let's just agree to disagree. |

But it does not take very much time to see the strong similarity between the two rails, even down to the weight, tube design , size and function, elongated slots, 45 degree offsets, similar mounting system, and use of tab type fasteners ("T" shaped rather than "L" shaped). I'm not saying BG copied the MFR. I am saying that perhaps great minds think the same way. BG could use M-Lok without paying someone as it is open source. He did improve an already very sturdy mounting system, relying on strength rather than removing material and possibly compromising strength. Were I buying today I might chose the Geissele M-Lok (although I'm sure it is actually out yet - not in stock), or chose the MFR. It would be a tough choice. Maybe DD was ahead of its time and that time has now arrived with BG's M-Lok design? |

"Secondly the LT-135 was designed to clear IR/laser setups, but if you use it for your purposes, that's great too."
It was necessary. From LaRue's web site regarding use of the LT-104. A direct quote: "Note on BUIS systems: Some BUIS will not fit under your scope in this mount. If you have ANY questions on your application, please call us. We are well versed in fitment. Do not automatically order the taller mount before consulting with us. Thanks!" So, I called LaRue and was told that with that outside diameter of my eyepiece and with an addition of a Butler Creek rear flip up lens cap (not depicted above) the thickness of that cap's base over the eyepiece would, indeed, cause the scope to hit the Magpul folded rear sight. Thus, I chose to follow their advice and not get the LT-104 and to select what they recommended, the LT-135. Hope that clears up the thinking. It's not just lasers and illuminators and the objective lens. My clearance problem was with the scope cap and the rear sight. Returning to the subject of the thread, yes, we will just have to respectfully agree to disagree. There are sound reasons to chose the MFR or to chose something else. |

How many of the others have 45 degree offset capability built into the slot system? That was a clear plus for me, one of the "better" factors, compared to other rails I was considering. It might weigh an ounce or two more than the lightweights, but is still lighter than many, especially after they put on rail covers to cover up the unused slots, but the extra ounce or two translates into a more rigid and strong rail system. Tube thickness is .150" of 6061-T6. Very strong.
ETA: I'd gladly put my KMR vs your MFR in a torture test anyday of the week, and again if Keymod was a fad the big names like KAC, DD, BCM, and Noveske would not jump on it as I don't think those guys follows fads. Actually, The fact that these manufacturers and many others making them and there's so much enthusiasm behind it is almost all the ingredients for a Fad, the last ingredient is time, and we'll all have to wait on that. I love the weight, profile and locking mechanism of the KMR. If I carried my AR any more than I currently do I'd get one for the weight saving alone.

Never called him a "fad chaser" nor did I say or imply that key mod was or is going to be a fad. I stated what I consider to be the obvious(based on the definition of a fad), that time will be the final determining factor if it will be a fad or not. You know you posted a video showing him with a war-beard and 70s Trans Am to prove he doesn't follow trends or fads? bit ironic |
