Brownell's has the KAOS for the 12" launcher in stock right now - just cut it.

I did a sponge-camo job on the Savage FV-SR. Came out great. More details in this thread:

Every other manufacturer out there just uses the shorter AR15 gas systems on the Big ARs, and says "It'll be good enough," rather than buy proprietary gas tubes from Armalite, or violate Armalite's patent on it all.

In order for Armalite to give the bolt carrier group the proper amount of gas, for the proper amount of time, and generate the proper amount of force in order to cycle the weapon, they had two choices: 1. Move the gas port in the barrel, which will affect dwell time, 2. Use a longer gas tube and keep the gas port in the barrel in the same place, with the properly developed dwell time. Eugene Stoner did the math on it all, and developed this. I think this is the why on this one. Actually, the AR-10 was developed first, and all this was "mathed out." I think the gas port location and gas tube length on the AR15 was changed, from the AR-10 design... That's gotta be it. There is no other explanation.

I really started thinking about this, and I think I have the answers. I'm pretty certain I know why the Armalite AR-10 gas tubes are longer. So, as I mentioned before, the carrier gas key will sit further back on the AR-10 than it will on any AR15. It's mounted the exact same distance back from the front of the carrier face, but the AR-10 bolt is larger, thus the gas key is further back when the bolt is closed, in the firing position. As it turns out, it's about 3/16" further back. 308AR BCG on the left, AR15 BCG on the right. Both bolts are pushed into the carrier, in the position they would be in when a round is fired.

With the purchase of 4, you're the reason they're out of stock... Shiit, that wasn't you, it was COBrien...

Lesson 65b. You snooze, you lose.

Here's the news writeup from Military.com Deadly Explosion at Army Ammunition Plant in Missouri Military.com | 11 Apr 2017 | by Brendan McGarry An explosion rocked an Army ammunition plant on Tuesday in Missouri, leaving one person dead and four others injured, the service said. The incident occurred around 1 p.m. local time at a "mixing building" at the Lake City Army Ammunition Plant in Independence, Missouri, according to Justine Barati, director of public and congressional affairs for Joint Munitions Command. "The four injured employees were evaluated on scene and refused further treating," Barati said in an email. "The explosion was in a primer mixing cell. The investigation is currently ongoing" to determine what caused the incident, she said. The facility is owned by the service but operated by Orbital-ATK and produces more than 1 billion rounds of small-caliber ammunition each year. About 30 government employees work at the plant, including 29 civilians and one soldier, according to the email. The slain worker and the others who were injured were all employed by the company, Barati said in a brief telephone interview with Military.com. A spokesman for Orbital-ATK didn't immediately respond to a request for comment but the company later posted a statement online. "We confirm there was an explosion today at the Lake City Army Ammunition Plant that resulted in a fatality of one of our team members," it states. "Investigation is underway. Our hearts and thoughts go out to the family of our fallen colleague." Officials with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, or ATF, have secured the scene and determined the area to be safe, but the plant has been closed for the rest of the day, Barati said. Employees should call their building hotline number before returning to work on Wednesday, she said. A press conference was scheduled for later in the day. Orbital-ATK on Monday received a nearly $100 million contract from the Army to produce 5.56mm and 7.62mm ammo for the service. The company and the Army have upgraded the facility in recent years to enhanced product quality, performance and efficiency, according to a recent press release. Since 2000, ATK has produced more than 17 billion rounds of small-caliber ammunition at Lake City to support U.S. and allied warfighters around the globe. The sprawling facility is housed on nearly 4,000 acres and includes 408 buildings, 43 magazines, nine warehouses and storage capacity of 707,000 square feet, according to the Army.

SHIIT!

Nope, not for a 37mm launcher It's only a DD and requires a stamp if it's 40mm. 37mm launchers can't shoot all the military M79 and M203 ammo, because that ammo is all 40mm. Nothing at all required (on a federal level) for a 37mm launcher.

I'm not schitting you - when Rob rolls up on you, he's "appropriately attired," JUST like that!...

YOU CAN'T STOP HIM. YOU CAN ONLY HOPE TO CONTAIN HIM.

Exactly - I paid YOU PEOPLE for a service, and I had to pay for it BEFORE it was completed. You owe me that service that I paid you for, so fuckin' CARRY THROUGH with what I already paid you to do. No other industry works that way, so we shouldn't take that shiit from an airline industry. Oh, an industry that figured out a way to nickle-and-dime you to death in order to make more profit. All this shiit we pay for now - is only to make some fuckers RICH. In the past, your ticket got you damn near everything, including a fuckin' snack or a real (airline-real) meal. Now, they want to take as much money as they can from you, and charge for everything that they can dream up. Fukc you, I bought the ticket - now get me to where you SAID you would... WITH my shiit... Motherfuckers...

Damn, brother... You've definitely gone Full-On Glock Fag on us... How the fuk are you gonna carry THAT kit-out, WITH the 13 OTHER EDC weapons you pack?!!? You might need to get fat again, so you can hide all this stuff easier... I'm just sayin'...

FUk that! I'd rather be hit with a real bayonet than that damn thing!

"Well he shoulda ARMED himself, if he's gonna decorate his saloon with my friend..." Fuk, I LOVE that movie!!!

I watched it go down, saw the setup, and was LMFAO the whole time...

You merged the wrong one with the wrong one. Should have gone the other way, brother. Whatever way you did it...

I just re-read this whole thread, and didn't see a reference in your thread here, OP, about that gunsmith and his comments. That's me mixing up information and threads, on the exact same subject. That must have been another person in the last couple weeks, with that gunsmith. We made a recommendation to the guy, based on what he was telling us, and the pics revealed the short gas tube. Immediate recommendation to replace it with the Armalite gas tube, check operation, and see how the problem was. Pick off the easy target, and see how it goes, you know, fix the obvious. He goes and tells his gunsmith that bit of info, and the gunsmith tells him that's not even an issue, and it won't change anything. Well, I say BS on that gunsmith, and here's why... It's come up that the carrier key sits further back on the 308AR than it does on an AR15 - it's in the exact same place from the front of the carrier back to the front of the key, but that 308AR bolt is alot bigger than an AR15 bolt, and when the bolts are seated in the carrier, in the firing position, that key is further back on a 308AR. That's issue #1. Next, Armalite vs. DPMS (and AR15) gas systems. Why Armalite gas tubes are longer than standard AR15 gas tubes (and DPMS_based LR308 parts), I have no idea. Why DPMS uses AR15 gas tube lengths for 308ARs, I have no idea... However, I DO know that Armalite knows their shiit, and they have a scientific, tested, proven reason for making AR-10 gas tubes longer. Whatever reason that is, you can know that it's a good one. Pat Raley could tell us all about it, I'm positive. That's issue #2. Next, that carrier key overlaps the end of that protruding gas tube, and it's for an exact distance/measurement. It's THAT WAY so the bolt carrier receives the proper amount of gas, for the proper amount of time, in order to properly cycle the semi-automatic weapon. Once that bolt carrier assembly has made enough rearward travel, it disengages from the end of that gas tube, and the remaining gas is discharged directly into the (now open) upper receiver. It's the excess gas you see coming out of the ejection port when your buddy fires his weapon... That is issue #3. Now, that leaves us here - with a gas tube that is NOT the proper length, and it's short by 3/16", that bolt carrier is NOT receiving the proper amount of gas, for the proper amount of time, and it's not fully cycling that bolt carrier assembly with the proper amount of force that it was designed for. It might cycle, but it's NOT going to cycle as it was designed to do... THAT cannot be argued. It's science and math. Done. Now, this isn't aimed at you, OP - this thread is just a target of opportunity to explain it. You are on the right track. I hope that other poster reads this, then prints it, and gives a copy of it to his "gunsmith." Thus endeth the sermon...

Mike what the fuk IS that thing?

Reminds me of helicopters. The CH-47 to be exact. That thing is a flying contradiction, just beating the air into submission, while it's trying to tear itself apart.... It's also my favorite aircraft to Jumpmaster, off the back ramp, hanging out the port side, spotting the DZ... freaking the fuk out of the poor jumpers because the can only see me from the knees down, and right hand in the fuselage - everything else is hanging out of the aircraft.

BS, there's something wrong with every plane. They take off well, and fly well, but a landing is nothing more than a controlled crash. I'd prefer for them to take off and fly me over where I need to go, then just let me the fuk out. I'll handle the landing on my own.

Yeah, Sheep...

It really comes down to whether the manufacturer(s) have their shiit together. With no set pattern to follow, even among the 3 different major types, things are all over the board with parts. Hell, when people say they're making DPMS-based parts, they can't even all be on the same sheet of music! You just have to watch everything you're buying. You have to really check out full rifles, really be picky about what parts you get, etc. Honestly, the only complete rifles I'd trust would be the high end stuff (DD, PWS, LaRue, etc.) and less expensive complete rifles that come directly from a major manufacturer (Armalite, DPMS, Windham Weaponry, RRA). I can't believe there was a gun store gunsmith that said that short tube wouldn't have any affect on the rifle... You have a barrel with a DPMS-based barrel extension on it, and Anderson obviously didn't drill the gas port in the DPMS LR308 position - they drilled it in the Armalite AR-10 position. Smaller manufacturer, doing whatever they want... That's what gets us, as we build these things...
