I love my free floated quads. I have only 1 upper each with a keymod and mlok rail. Doubt I will buy anymore.

Personally I cant stand mlok. I like keymod better out of the two.

My go to rifle has a DD quad. Just bought a fn 20' upper with a quad from kac. I'm a big quad guy.

When I go to the dinner I get a quad order of browns with two eggs and ketchup  I'm a through and through quad guy.

Mine are still kickin'.

I just ordered a BCM QRF 7" to put on a 6920.  It's half the weight of the RISII that's on it now.

Did Keymod and MLOK, I'm sticking with quads and plastic double heat shield Colts.

Free floated mlok/keymod rails tend to be easier (and therefor cheaper) to manufacture than quad rails, since you can start out with a smaller piece of metal that spends less time in the CNC machine.

And being lighter and smoother is obviously also nice.

For a standard issue rifle for a police department or military where it keeps getting turned into an armory and re-issued to different people who keep removing and adding different attachments to it in different configurations, I think quad rails make more sense. Installing/uninstalling stuff on a quad rail is much more idiot-proof than on mlok.

But for a civilian customer who attaches their stuff on the rail the way they want it once and rarely or never changes it, I think mlok/keymod makes a little more sense.

Then again, even as a civilian I do like the idea of not needing to have an allen wrench to install anything on my rail. Being able to set stuff up with a flathead or even a lever like on some of LaRue's mounts would be cool.

I think they’re just fine. MLOK is pretty good too although I attach sections of Picatinny where I need them and rarely actually use MLOK attachments.

The only one I don’t like, and have removed, it keymod...I just hate the look. After covering it completely with rail covers, it’s thick and heavy.

I agree with the move to slick sides and adding pic sections at 3-6-12 only where needed but I think threaded solutions as done by LMT, Colt, LWRC, SIG, Geissele Mk1, etc. were the answer. I absolutely fucking revile MLOK and don't understand why people like it. I'd rather have a quadrail.

I divested myself of the last of my MLOK products last year and have unified onto either pic or threaded pic sections on everything. Never liked KeyMod. I tried to like MLOK, I really did, but it's like taking a step backward solely because everyone else is doing it. I'm not doing it anymore, I'm out.

Prefer quad for strength or the dicks for convenience, but to each his own. Not mad that there are more options.

But the market seems to think that the average AR buyer has soft, baby sized hand that need smooth, tiny rails, and lacks the upper body strength to handle the extra 4 ounces of weight.

My DD Omega is just a tad too slim IMHO.  When I tried using my Thorntail adapter, the SF Scout light wouldn't clear the front hand guard cap.  On the other hand, my Troy drop in quad rail worked just fine, but is significantly fatter across the horizontal plane than the Omega.

Had the same problem with my omega/thorntail combo.  Swapped the regular thorntail arm for an SBR thorntail arm.  Set it to where the mount ends right at the handguard cap.  Makes the light go out just past the FSB.  Works pretty well.

Their fade into obscurity will be a lot slower than Keymod, IMO, just because so many manufacturers have already invested into numerous models, but it’s slowly happening.

DD has pared down their quad lineup pretty significantly over the past few years, same for KAC.  Only new “mainstream” quad rail design I can think of is the QRF.

I don’t think they’ll ever go away completely, but when .mil begins switching over to something more modular, I think their market share will start sinking like a rock.  The civilian market has started moving on and without there being a potential .gov purchaser, there isn’t much incentive to update and modernize current designs, let alone continue producing them in the numbers they currently do.

It’s pretty telling of the times to come when you examine what’s being sold on the majority of new rifles, and that’s modular.

Mk18 RIS II rails still probably cost one of your testicles. I would love a Mk18 build personally.

I always wanted the quad rail from Transformers 3 for my ACR but those were custom made and would cost a shitload to reproduce, so I'll never get one. I'm still using the polymer handguard.

Other than to replicate those two rifles, I have no real desire for a quad rail.

As expected. Currently not as many MLOK accessories either, most people have dozens of old accessories that attach via rail. That is why a lot of the MLOK rails have some picatinny quad rails up front or people bolt them on. As time goes on and people buy newer accessories they'll start making a bigger switch.

But you can argue it has already happened on the civilian side. Most new factory ARs come with MLOK rails. Since they're cheaper (or should be) it is a no brainer why the switch has happened if for higher margins than anything.
