DD4 RIII - Featuring the RIS III Rail with ‪@GunsAndAmmoMag‬

[@ralphfrasca4168]

Got my M4A1 RIII a few days ago on birthday and i absolutely love it!!

[@SmithandWessonBlazer]

Long time MK18 owner but 11.5 will be the reason I actually buy another DD upper or possibly a complete rifle.

[@DanielDefense]

I'm glad we were able to make that possible for you! For the 11.5" barrel length, you'll want the DD4 RIII S. Thanks for choosing Daniel!

[@Texasbroski512]

Ddm4riiis in FDE with BCM or PSA lower ssa-e X trigger Reddot will be my next build rest of thr built TBD

[@EastCoastMan603]

Love you guys. I appreciate improvement and advancement... Yet A clapped out RISII is forever in my heart and hand. #QuadSquad for life.

[@charlesmullins3238]

Absolutely love my dd5v3…it will drive tacks and like you said that lower is awsome

[@stevegibbons2197]

Hoping to see the new DD ambi lowers being available at some point so I can run it with one of my existing DD uppers.

[@user-nr7xk9pl7r]

yes, but i doubt it, they're going to make you buy a whole riffle......

[@Dan-di9jd]

I bought the whole rifle and put the upper on a spare lower that I put on consignment. Hope to recover my cost.

[@aliceburte9278]

Awesome thanks guys 👍🇺🇸

[@TerraRyzer]

Loving mine on my Mk18 build. Would love a 15" version of this Handguard for 16" barrels

[@Tony27654]

This is a big improvement

[@SM-eu5xl]

Excellent! Admitted Daniel Defense fan boi..

[@1ghostshooter]

Outstanding Daniel Defense and Marty Daniel thank you for making a wonderful product. Love the shooting range. Is it private range?

[@tonieskonen5665]

Here dd m4a1 riii. Love it💪

[@timrainger8908]

Those things have that sandpaper new sound.

She's a beaut, Clark!

[@ChrisThompson4UD10N0T]

Awesome

[@leonardosalcido821]

Ris || still king 🤙🙏

[@shooterscott]

But what do I do now? I like the quad rails.😂🤷🏻‍♂️

[@RJGuitz]

Been running a 10.5 suppressed Radian Model 1 SBR for 3 years now... got this tingly feeling to purchase a 10.3 DD RIII...

[@JohnZ556]

It is sweet! Thiccc rail for all your Xmax tree needs and comfortable! But I would just suggest double check the bolts on the rail they might not be up to 28-32 in-lb per DD spec.

[@DanielDefense]

Yesss! Go with that tingly feeling! We'll be here for you when you ready.

[@RJGuitz]

@garrett3174 I have an 11.5 SOLGW M76, which I am also planning to suppress in the future. My RC2 lives on the Radian and I'll probably get a B&T for the SONS.

[@JohnZ556]

@@RJGuitz The M76 13.7 is smooth to shoot suppressed or not. But I don't like the accuracy at its price range. BCM or geissele can be very good for 11.5 choices. Or you could go LMT, Or even Bren2 for a wild card.

[@Rob.The.Builder10]

This isn’t a want this is a need

[@jayphillips368]

I run an LWRCI-DI and want a second rifle, the ambi controls will provide a similar manual of arms, think I'll snag one!

[@Tearitory]

I know it has nothing to do with the video but I would love to see a delta 5 pro in 300 prc/win mag.

[@pd5156]

When 12.5 midlength barrel?

[@skullofserpent5727]

I am poor and can't afford multiple ARs, so I bought a DD and called it a day😂

[@DanielDefense]

This is the way! Thanks for choosing Daniel!

[@Rapture_11B]

Imagine being a left handed grunt running a long gun right handed XD

[@tWo_fOoT_oNiOn_1775]

Quad rails are superior 😎

[@markm6015]

Carried daniel uppers in the GWOT worked everytime all the time.

[@HWG-wm8ld]

Sure you did kid.

[@user-xm4bd1ve5v]

I'm Japanese, but I like DD's rifles.

[@Glocktavius_the3rd]

What does being japanese have to do with anything ?? Do japanese people in general hate on DD Rifles? 😂😂

[@superfamilyallosauridae6505]

tell LMT to MAKE MORE M203 MORE FASTER so that we can actually install some on our RIS II/IIIs

[@nateez3898]

How long do Daniel defense barrels last? Approximately how many shots can you expect with proper maintenance and barrel cool down time?

[@AdoreYouInAshXI]

20,000 rounds is the typical, general number. There isn't an exact number. And it's not like the barrel will all of a sudden become useless near the end of it's life. You'll just gradually see your groups start opening up when the barrel gets shot out. So you may go from 1-1.5 moa to 3 moa to 7 moa. Realistically unless you're shooting for a living (as some KZbinrs do), or shooting serious competition, the barrel will probably last you as long as you need it to. Even when it starts to show it's age it'll still be more than useful for any type of self defense situation.

[@Dan-di9jd]

In my lifetime I only shot out 2 barrels. They lasted roughly 12k-14k rounds before they keyhole with 55 gr. They would shot 77grs. The first barrel was a bcm and the second was this DD barrel I got with a urgi upper from geissele back in 2019ish.

[@Dan-di9jd]

Replacing barrels pretty easy. I have a Colt socom barrel I’m running now. Barrels are consumables so don’t get hung up on it but when you consider the ammo cost vs the number of rounds it’s pretty worth it. Right now my current barrel is at 4K rounds and moved 1 ring on the throat erosion gauge. At this rate I suspect it’ll last roughly the same as my other barrels.

[@CA.0verview]

Are the 14.5” rifles still coming in with carbine gas systems ?

[@DanielDefense]

Depends on the rifle model! The newer M4A1 RIII comes with a mid-length gas system. The classic M4A1 is still available with the carbine gas system.

[@CA.0verview]

@@DanielDefense excellent , consumers will enjoy mid-length .

[@mrshort2379]

I love the DD RIS III but being a poor I could "never" afford one, at least not without have to sell an organ. Daniel Defense "could" make us a poor mans RIS III now that would be awesome if they did or would

[@HWG-wm8ld]

Locking the bolt to the rear is needed how often? It isn’t worth the extra cost and accidentally causing a malfunction. Ambi sucks

[@patriotfamily8345]

I’d love one of these if it didn’t have an unconstitutional tax stamp requirement.

[@timb8970]

Why are your guns so expensive?

[@aaronpark1738]

can you use this with the ddm4 isr?

[@DanielDefense]

Unfortunately, no. The RIS III Rail's inner diameter is not large enough to fit the ISR's suppressor.

[@byronbranch4645]

Hey...im left handed 🥲

[@crambow]

my DDm4 RIII us bit ambi :(

[@GuacIsExtra99]

What’s the msrp on the 14.5?

[@DanielDefense]

For 14.5", you'll want our M4A1 RIII. To not anger the YT mods by posting prices, please visit our website for pricing and specs: danieldefense.com/m4a1-riii.html

[@motorcarclassics2922]

What was the thought process on going from a 1 piece rail to a two piece?

[@DanielDefense]

Our RIS III rail system is modeled after the proven RIS II developed for SOCOM, but now in M-LOK for extreme durability with less weight. The versatile two-piece design allows for removal of the lower rail section and easy attachment of M203 (or M320 with adapters) grenade launcher (RIS III 12.5 and 13.0 rails only).

[@motorcarclassics2922]

@@DanielDefense So your 14.5+ rails are 1 piece design?

[@DanielDefense]

@@motorcarclassics2922 Yes, both the DDM4 Rail 15.0 and MFR 15.0 Rail are one-piece rails.

[@roberthsieh8639]

@@DanielDefenseis there any utility adding on the m203 for civilians? As a 91f (small arms repair) will i have to service this in the army lol

[@Devin7Eleven]

@@roberthsieh8639Never saw the need for an M203. Wish I went with a DDM4V7 instead. I’m not wanting to play thousands for a grenade launcher.

[@invaderjoshua6280]

I hate that new rail so much. The old one that went all the way to the muzzle looked so much better.

[@bestjobieverhad9584]

Stuck with a milspec lower..... i dont understand. Even with a fence around a ambi mag release. Theres things on your chest rig that will poke that mag out

[@HWG-wm8ld]

For sure. They are damned if they do and damned if they don’t.

[@JohnZ556]

IKR? And the way DD4's ambi bolt release layout doesn't actually make the right-handed user faster as the bolt release is just too high up to use without breaking the grip. I guess they truly just added more buttons for the lefties to use.

[@Stephenhardey]

Love it guys….but let’s be real….ANY 10.3 without a ris II rails ain’t no MK18 👽

[@JohnZ556]

🧐Quad is cool but RIII is way more functional, comfortable and equally if not more sturdy(within a ounce to RISII). Most people just cover up their quad rails anyways. It's 2023, I don't mind building a 10.3 with all the modern parts to my liking: M4E1 lower , Phase5 lever, Hiperfire. Unity Fast CompM5 + Unity Eotech 5x on top with Arisaka Modlite and PEQ linked by AXON. (I know, only 10.3. 5x is more for scouting and PID in a real environment. Doesn't hurt it also helps with balance) They engraved it 'MK18 RIII' so not a true 'MK18', nor do I want a true MK18 config since we have better options now.

[@jacklewis3444]

AMBI LOWERS ARE NOT WORTH IT. I’ve had DD and several other brands and my magazines always find a way to fall out when I sling my rifle against my body armor
