“Brownells Gun Tech™ Caleb Savant is at the bench to show us how to install Daniel Defense’s RIS III Handguard, one of their Rail Interface System M-LOK® handguards for the AR-15. The RIS III uses the Daniel Defense SIX-bolt lockup system for securing the handguard to the receiver.
Tools you’ll need: (1) Daniel Defense barrel nut wrench and (2) the hex wrenches that come with the RIS III, plus (3) Midwest Industries Upper Receiver Rod or a similar vise block to anchor the upper securely in the (4) bench vise, (5) adjustable torque wrench, and (6) Brownells Action Lube Plus® or similar grease. The RIS III is designed to fit a standard mil-spec AR-15 upper. It will work on billet uppers that have the necessary cutouts at the front (Caleb shows us).
Clamp the upper in the vise via the MI receiver rod. Put a little Action Lube Plus® on the outside of the barrel extension to help you slip it into the receiver. Slide the handguard bracket over the barrel and against the receiver. Put a little grease on the threads of the barrel nut and install it on the receiver, hand tightening it as far as you can. Use the barrel nut wrench and torque driver set to 35 ft.-lbs. to tighten the barrel nut. Install the gas block / gas tube.
Slide the RIS III over the barrel up against the bracket, anchoring it with the six screws. The two SHORTER screws go on the bottom of the handguard. Daniel Defense includes a hex wrench for these screws, but using a ball-tip wrench will make the chore way easier. Make each screw snug, but don’t fully torque them down until they’re all snugged on. There should be NO gaps between the rear of the handguard and the bracket. Now, install the bottom panel of the handguard. Bonus: you can use a slot, hex, or Torx® head driver to tighten the screws that retain the bottom panel.
When you’re done, the Daniel Defense RIS III brings a new meaning to the concept of a “”rock solid”” M-LOK® AR-15 handguard installation!

So this rail works with a mil spec upper correct?
You could use your hairspray as loctite..
My DD M4A1 RIII is in the mail! I'm so excited
So do you not need to season the threads like with other nuts?
The RIS III is the only thing I'm missing in my life. Please Brownells, bless me with a RIS III!
I like Brownells so far, but DD are grabbers. Don't patronize DD if you care about 2A. Research it.
when will they release
Can this handguard be installed on an existing barrel/receiver, or does it have to be part of an initial build?
Absurd to pay that much when Aero or Ballistic Advantage (or hell, even Brownell's house brand, 'AR Stoner') has nearly the same features and construction.
Why are you putting grease and not loctite or something? Grease seems counter-intuitive in my opinion.
Does the hand guard not flex a little at the front? I’m concerned about movement of the hand guard effecting the front sight.
yeah i have a question ummm do they sell just the handguard?
Step one throw in trash
Step two install RIS 2
Step 3 1913 Rail Master race
I have zero experience because i cant get my hands on one. I wish i can find it in stock
Please do another demonstration with the optional m203 installation. Lol
You got some soft hands there buddy. Why not get a real man to do this commercial?
sold out of course.
BRO PLEASE CUT THE SIDES OR GET A NEW HAIRCUT
Nice AT4 in the background
Cool. Now sell them.
13:30 to 13:37 I don't know why I love this so much… BUT I REALLY love that he said it
This is unrelated to this video but I have a question. I recently installed a Magpul ASAP QD end plate on my lower receiver. When I reinstalled the castle nut it kept turning the buffer tube off center. As someone with severe OCD how can I apply torque to the castle nut (I did not over tighten castle nut) without spinning the buffer tube off center so my stock isn’t canted? Help! Please and thank you.
great video.
DD RIS Rails in general are freaking bomb Proof.
Finally, a product for the many of us who use grenade launchers at the range……
I'm personally a much bigger fan of the RIS II Quad rail. It's so darn sturdy and practical.
Time for upgrading handguard. Thanks for showing it.
Fantastic step by step tutorial. Thank you!
Wait I was always taught to tighten break tighten to higher lbs break it then tighten down a final and third time was I taught wrong?
I wisIh could have one of these…. so nice
The cris-cross ONLY matters during the torque process…. NOT necessary when installing screws/bolts finger tight. Once torquing the begins YES cris-cross is required. For anyone “not” familiar with mechanics and the science/principal involved in the torque process.
The cris-cross pattern while torquing is required to prevent warping of the object requiring the torque so that it properly tightened. Warping can be caused by the force of torque applied unevenly and results in improper torque and tightness required for both safe operation and to prevent mechanical failure of the joined stress points.
Wow, this looks like a great…wait…$486 for a handguard?🥴😳
Yeah, hard pass.
What is the piece you pet in the vice to hold the upper receiver?
I'm sorry "C" but I got to ask…. what did it take for Brownells to post a "how to" video when the rest of us would have had it deleted and or a strike…Even MI, and other manufacturers, got strikes for posting said videos…
As what I was taught, you should "set" your barrel nut at least 2x before you torque it down…being tighten, loosen and repeat then torque. This will "Set" the threads…also with a set-screw gasblock I use a "tiny" drop of vibra-tite on the barrel, well away from the port, then tighten it down and wait 24 hrs before shooting…
Who else checked to see if it’s in stock and it’s not
Awesome hand guard and video
Top hat?
Bcm mcmr is easier and better designed imo , this is a classic tho 👌
Caleb, does the gas block need pushed against the barrel shoulder, or leave a .030" gap for gas port alignment?
I heard a .030" gap was meant for older handguards using end caps.
Are risiii rails sold separately already?????
If anti-rotation tabs is not press fit to the upper they are FALSE anti-rotation. They are merely rotation limiter which then if handguard rotation little but tile one of those tab arrest the rotation by then all your zero on handguard are ABSOLUTELY LOST! UTTER TRASH Daniel Defense RIS crap. Buy upper with pin hole for anti rotation pin with wedgelock handguard they are unmatched along with Noveske NSR and Monolithic uppers.
If you are going to talk about mounting a grenade launcher, then by all means, mount a grenade launcher. Or doesn't Brownell's sell a grenade launcher.
Im gonna be honest. That rail looks super out dated, heavy, and too proprietary.
Is DD selling the RIS 3 rail by itself now? Want to add it to my Christmas list lol. 🎄 🎅🏼 #JakeHunter88
Great!
Geissele all the way…..
Beautiful looking rail. Probably should have mentioned that the 6 bolt plate will mate up to the mounting plate of the older RIS rails. If someone has an older RIS quad rail they can unbolt the old one and put on the new Mlok model without having to pull the barrel.
I’ve ever wonder about your work bench and vise. Where can I get those?
QUAD SQUAD FOR LIFE !
