Many are familiar with the RIS II Rail system. Built to run a free float rail on a M4A1 Carbine, full quad rail, and still be able to mount the M203 granade laucher - and keep the rail. It became standard equipment in SOCOM in 2005. They just released the RIS III Rail, and yes, I will be getting one. Here's one writeup on the release, from Guns & Ammo magazine: https://www.gunsandammo.com/editorial/daniel-defense-riii-556-nato-rifle-ris-iii-rail/467335/?utm_source=GATdaily&utm_medium=email&utm_campaign=12_22 Daniel Defense RIII 5.56 NATO Rifle & RIS III Rail Drawing on its long history of providing premium rifle components to U.S. Special Operations, Daniel Defense has updated its rifle and rail offerings with the RIII in 5.56 NATO and RIS III handguard. December 20, 2022By Tom Beckstrand There’s a fair amount of interest in the guns of the U.S. Special Operations community due to the selection process associated with them. These guns go through a ton of abuse before they are ever fielded, and then they must perform under austere circumstances for years if they expect to remain. This makes for some compelling research and development for the commercial consumer because none of us have the time or money to beat on guns like the they do. I like to keep track of what’s serving in this part of our military because it speaks highly of the companies that build the products for the market. Daniel Defense is one of those companies, and they’ve been making AR-15 forends — i.e., “rails” — for almost 20 years. The rifle issued to U.S. Army Special Operations at the turn of the century was a modified M4 carbine. It featured a quad-rail handguard that replaced the factory plastic handguards. This meant that everything touching or mounted to the handguard — light, laser, foregrip, etc. — might as well have been mounted directly to the barrel. The rifle’s accuracy suffered as a result. In 2005, the United States Army Special Operations Command (USASOC) decided to upgrade their issued M4A1 and picked the Daniel Defense RIS II. This resulted in some significant improvements. The first was that it divorced the barrel from the forend (and everything mounted to it). The barrel became “free floating,” and accuracy improved while also becoming more consistent. Next, the handguard was increased in length from 71/2 inches to 91/2 inches on carbines with a 10.3-inch barrel, and 12 inches on the 141/2-inch barreled guns. That additional real estate mattered a lot when shooting from field positions with lights and lasers mounted. Finally, the RIS II allowed the military to attach a grenade launcher to the handguard instead of the barrel. In what should be a surprise to no one, this improved accuracy significantly on those as well. Daniel Defense also saw the adoption of its barrels within SOCOM as part of a product improvement program. In 2015, USASOC decided it needed to further update its rifles with a better barrel. The M855A1 Enhanced Performance Round (EPR) had been out for a few years, and it was a higher-pressure load than anything previously fielded. The additional pressure was hard on the barrel’s rifling and SOCOM saw barrel life drop precipitously. They decided to adopt Daniel Defense’s hammer-forged and chrome-lined 141/2-inch barrel with mid-length gas system. (I remember being shocked that USASOC took AR-15 barrels seriously enough to come up with the right answer. Later, I came to find out that a couple of friends of mine were responsible for that project, so I shouldn’t have been surprised.) Hammer-forging the barrel work-hardens the bore and makes it more resistant to wear than cut- or button-rifled barrels. The military previously used button-rifled barrels, so the new hammer-forging process gave them a measurable increase in barrel life. Lengthening the gas system allowed the bolt to stay closed longer and let chamber pressure drop before unlocking the bolt to extract the fired case. The M855A1 quickly earned a reputation for shearing bolt lugs when the bolt twisted to unlock for having a higher chamber pressure. Lengthening the gas system provided some much-needed relief. USASOC liked Daniel Defense’s barrel so much, they continue to use it today. All of that tribal knowledge has made its way to the newest rifle from Daniel Defense: The RIII. This rifle features a forend that attaches to the rifle in the exact same manner as the RIS II, but it replaces the long sections of Picatinny rail on the RIS II with smooth, hand-friendly sections of M-Lok. M-Lok is SOCOM’s attachment method, so it’s no surprise to see it on the RIS III ($476).

^^^ That's what I was gonna recommend.

Man, they're like mountain goats. With no shoes. Unreal.

That's cool. We, here, helped test and develop the lube that Rex suggested. It went YEARS here. .308AR.com was the testbed for this stuff. All across the country, in varying weather conditions. Roman even poured dirt INTO his gun, testing this stuff. Stick with what you know - but not until you try this stuff.

Yep, that Necro went 10+ years, right there...

That second one's startup reminded me of this, brother. New Dodge Drag Pak being offloaded at a dealership. I want one of these bitches SO DAMN BAD... It hurts...

That's a seriously fucked up piece of terrain. It's just north of J-Bad. Jalalabad, damn near on the Pak border. I was in that exact area - and all around it to the north and south. That was late 2003, winter time. Up there in the mountains fucking around in the snow. Some of the valley floors that we were inserted into were at 8,000 feet. My job after that... climb. Gain the high ground. I don't miss that place.

I love it, AL!

^^^ Best stuff on the Planet, right there.

^^^ He was a Leader, all the way through and through. I wrote a paper about him in a class assignment at a school I had to go to. Badass, all the way.

Yeah, brother! The supply CPT was more of a friend. All those dirtbikes were taken from Noreiga's beachouse at Rio Hato. Since he was the supply CPT, he was in charge of all that seized shiit. He told me anything I could get started, I could use. Except, there were no keys to anything... Heheheeee.... No problem... He told me I was never gonna get that Pilot started. When I got it running, he told me to go RIP THAT THING! And I did, straight down the damn airfield...

Gas tubes extend 0.600" past the gas tube roll pin. If you can measure the end that's in the gun, all the way to the gas tube roll pin, add 0.600" and that's the overall length you have. It's not a half inch. It's 6/10th inch. Big difference, when you're looking for proper gas timing. Gas tubes are too easy to just remove, and measure end to end. That's what I'd recommend. Just pull it, and check it.

Yep, I don't run K&Ns on forces induction engines. Only on naturally aspirated engines.

I airlanded at Tocuman, after the Rangers fucked that whole international airport up. Then did the Relief In Place for the Rangers at Rio Hato airfield. I got in big trouble at Rio Hato, made CNN during a newscast back in the day. I have a video saved somewhere on al old computer hard drive of my major fuk up on Big Time News. I was "the hotwire guy" for the Brigade. Need a vehicle? Go get Hartley - tell him to get us something. At Tocuman, I hotwired one of those little baggage train tractors, so we could move all our shiit. That started it. Later, I had to hotwire I M1008 that took a rocket - "JUST MAKE IT WORK AGAIN!!!"... "Roger, Sergeant Major, done." I had to hotwire a fucking ice cream truck that was abandoned - and I used that bitch for resupply runs, for batteries and water runs. That was an epic one. Once I found Noriega's stash of personal dirtbikes and Honda Pilots, at Rio Hato... I was on fire. I hotwired dirtbikes so the guys could ride them - but my prized possession was hotwiring that fucking Honda Pilot. One I lite that thing off, with a broken throttle cable - I tucked My M16A2 inside, got in, feathered the throttle - AND HAULED ASS!!!m STRAIGHT DOWN THE AIRFIELD, WIDE OPEN THROTTLE!!! Since the throtle cable guide into the carb was broken, YOU JUST COULDN'T LET OFF THE GAS! And, I didn't... COL Burney was giving a press briefing to CNN - and I'm RIPPIN' DOW THAT AIRFIELD right behind the cameras... On live TV. FML, afterwards. I was called in, chewed up one side and down the other by the Bde CSM for it. COL Burney comes in to KICK MY DICK IN, FOREVER... and says, "SGT Hartley... that was YOU on the airfield on that thing?... Haven't you been hotwiring all this shiit so far, by yourself?..." "Uh, yes Sir! The luggage cart, blown-up CUCV, the Ice Cream Truck... YES SIR!" I got over... BIG. TIME. COL Burney let it go, right then. Moral of the story, men - have a skill. That others need, and can use... My CPT was SO PISSED OFF AT ME...

I vote Athlon. for the glass.

Found this one - it's from last year, so 32 years then - never found it when it came out: https://www.army.mil/article/252920/7id_history_operation_just_cause_32_years_ago_today

Rem 700 AAC-SD, with the Battle Arms BAD-DBM - before I moved it all over to the MagPul stock. EDIT - snatched it out of this oldass thread:

33 years ago, tonight, brother. I was in 7th Infantry Division (Light) then. No better combat infantry division to be in. Ranger-heavy, in all leadership positions, all the way through. Had to be Ranger qualified to hold a leadership position at E7 or above. 70% graduation rate from Ranger School. Badass place to be assigned to in the mid and late '80s, and I loved every second of it. I went to the Division Pre-Ranger Course, smoked the fuk out of it, came out Honor Grad and Land Nav Award. Division CSM was at the grad, and I was in front of the formation as the Honor Grad, he asked "SGT Hartley, what do you want me to do for you?" My response: "CSM, I want the very next slot that Division gets, straight to Ranger School..." His answer was simple. "DONE." 2 weeks later, I was at Fort Benning, in Ranger School. Smoked that fucker, too, straight through, no recycles. Damn near had Honor Grad from that, but some cheesedick LT beat me out by mere grading points, overall. That's some back-to-back hardass schools that are hard to pull off, with time in between. I had NO time in between. Suck it up, peaches, you asked for it - you better back it up... FML! My Brigade Commander at 7ID(L) was COL Linwood Burney. If you read the book about Hamburger Hill, Viet Nam - part way through that book he was "1LT Burney" and the rest of the way through the book he was "CPT Burney." Battlefield promotion, during the fight at Hamburger Hill. That is the baddest motherfucker I've ever been in the presence of, in my life. Been around a couple bad motherfuckers while on this rock - but never anybody like him. He LOVED his NCOs. He HATED his officers. He rode his Officers like a Circus Pony, HARD. He always praised his NCOs, and would help them in any way possible. Anytime we had a Division Run, 2nd Brigade would run another 7 miles, after the end of the Division Run... Because, COL Burney. He wanted to run until all his Officers fell out of the run. Hard motherfucker. I learned so much from that man - and I was lucky I was an NCO, not an Officer... That guy is Sun Tzu, reincarnated... COL Burney - he was 101st during Hamburger Hill, so that's up there, that was his Combat Patch - SSI-FWS (Shoulder Sleave Insignia - Former Wartime Service) - his Eagle is on him in this pic, during his Brigade Command at Fort Ord - that's the pic of him that was in Brigade Headquarters, as the Commander: After Panama - tonight, 33 years ago... My SSI-FWS (Shoulder Sleave Insignia-Former Wartime Service) was the 7th ID(L) patch, for many years. I added a couple more over the years, and have been blessed with good people, in lucky situations. I've earned the "Light Infantry Trifecta" over the years. 7th ID(L), SF and RGR Bn. I know this will come up, so I'll post it now.

Tonight, men, all across America... Back in 1989... There were planes in the air right now, as I type this, at this time. 9:13pm local AZ time. Already in the air, for the most impressive Invasion the United States of America has ever conducted. If it's a small force, it's called a Raid. If it's a large force, onto a country, then it's an Invasion. There were alot of people on their way, right now as I type, for the Invasion of Panama, 1989.

So... you measured 11.125"... ...and they say it should be 11.750"

That's a regular midlength AR15 gas tube size. You need to see where it ends in the cam pin cutout in the upper receiver. It should end right in the middle of the cam pin cutout. Take a pic and post it up here in this thread. 18" midlength gas with a 0.750" journal needs a gas port diameter damn close to 0.085" - if you have a proper recoil system. 16" midlength, with 2" less dwell time, will need to be 0.090" port, maybe a touch more - with a proper recoil system. So, now that I've said that twice - what recoil system are you running on this gun?

Looks like I'm scoring bigtime this year on her shiit. A Larue 158 mount, another Athlon Argos BTR 6-24x50 mil scope, a .260 Rem gun, a badass 18" 5.56 precision gun, a bunch of Olight lights, multi-tool and a knife, K&N cold air intake for a Dodge truck... I'm keeping it all for myself. Oh, I'm keeping the Ruger PC Carbine takedown in the MagPul stock, and the new PA mini red dot that goes on it, too...

It's never too late, brother - thankfully, we finally got the meet-n-greet done, and now we can get down to business...

Started it's life as a factory built DPMS gun, then.

We've had the Range Master from Dillon over for a shoot a few years ago. His name is Skip. He brought the crazy girlfriend that didn't like Ron... That was the year that I brought out the electric chainsaw, and Kate and I @kdawg0124 went looking for firewood in the middle of the night. We came back with MASS firewood - and I cut it up with the chainsaw. Skip's woman - when we left for "the gathering" said "Who brings a chainsaw to the desert?!..." THIS GUY does...
