 16" PRECISION BARRELS WITH INTERMEDIATE LENGTH GAS SYSTEM

"SMOOTH" IS GOOD.

WHEN YOU GET TO SHOOT AS MANY DIFFERENT AR' CONFIGURATIONS AS PAUL AND I DO, THE DIFFERENCE THE LITTLE THINGS MAKE BECOME MORE EASILY NOTICED AND APPRECIATED. WE LIKE OUR CUSTOM UPPERS TO RUN "SMOOTHLY". IT IS A DIFFICULT QUALITY TO QUANTIFY. SEE NEW AR' GUY'S CRITIQUE OF OUR 6.8 SPC UPPER SEVERAL YEARS AGO ON THE UPPERS, LOWERS, ETC., FORUM, WHERE HE COMMENTS AT SOME LENGTH ON THIS QUALITY IN OUR WINNING ENTRY.

ANOTHER NOTEWORTHY EXAMPLE REGARDING THIS "SMOOTH" RUNNING QUALITY CAME FROM A SPECIAL FORCES WEAPONS GUY WHO TOOK ONE OF OUR 10.5" GUNS ON DEPLOYMENT TO THE ROCK BOX. HE SAID IN TRAINING UP WITH THE NEW WEAPON, HE HAD TO RECALIBRATE HIS "FEEL" FOR THE PLATFORM. IN HIS WORDS, "IT FEELS LIKE THE BOLT IS CLOSING ON AN EMPTY CHAMBER EVERY TIME, WHEN IN FACT IT IS FEEDING PROPERLY." HE ALSO REPORTED CONFIRMED HITS ON SOME "MAN-SIZE" TARGETS AT 600 YD WITH IT. YES, IT WAS A SUB-MOA 10.5". MAYBE COINCIDENTAL - BUT PROBABLY NOT.

A GUN THAT RUNS MORE SMOOTHLY IMPLIES ONE THAT RUNS MORE RELIABLY, MORE CONSISTENTLY, AND WITH WITH BETTER ACCURACY. ALSO, A SHOOTER CAN RUN A SMOOTH GUN FASTER THAN ONE THAT HAS THE TYPICAL "CHOPPY" QUALITY TO IT.

WE PLACE GREAT EMPHASIS ON GETTING THE BEST QUALITY COMPONENTS BUILT TO THE HIGHEST TOLERANCES IN OUR CUSTOM BUILDS. THIS MEANS "STRAIGHTER" PARTS, PRODUCING LESS FRICTION. ANOTHER CRITICAL ASPECT OF A WEAPON'S "SMOOTH" QUALITIES ARE OPTIMUM PORTING FOR THE GAS SYSTEM, RECOIL SPRING, AND BUFFER WEIGHT, AS WELL AS PROPER LUBRICATION. THE IONBOND DIAMONDBLACK COATING ON THE BOLT CARRIER GROUP COMPONENTS THAT MSTN PIONEERED ALSO IS A BIG CONTRIBUTOR TO THIS.

IT IS ACCEPTED AS FACT AT THIS POINT IN TIME THAT A MID-LENGTH GAS SYSTEM IN A 14.5" TO 16" BARREL PRODUCES A SMOOTHER FELT RECOIL PULSE, LESS WEAR AND TEAR ON THE WEAPON, AS WELL AS ENHANCED RELIABILITY THAN THE ORIGINAL FORMAT CARBINE LENGTH GAS SYSTEM. SOUND SUPPRESSOR USAGE TENDS TO GREATLY EXACERBATE THESE DIFFERENCES, TOO. AS A RESULT, WE WOULD NEVER CONSIDER USING A CARBINE LENGTH GAS SYSTEM IN A CUSTOM 16" BUILD. MID-LENGTH HAS BEEN THE PROVEN WAY TO GO IN THE 16" FOR SOME TIME NOW.

WHEN THE NEW KNIGHT'S ARMAMENT SR15 E3 HIT THE STREETS, I WAS MOST IMPRESSED WITH WHAT AN OUTSTANDING JOB THEY DID IN BALANCING THE RECOIL SPRING AND BUFFER WITH THE GAS PULSE IN THEIR LONGER THAN STANDARD MID-LENGTH GAS SYSTEM. THIS RIFLE IS AS SMOOTH RUNNING AS YOU CAN FIND, EVEN AT ITS ULTRA-LIGHT WEIGHT, AND REPRESENTS A TREMENDOUS VALUE FOR THE MONEY. WEARING JUST A GENERIC A2 FLASH HIDER, IT PRODUCES LESS APPARENT RECOIL THAN SOME UPPERS WITH COMPENSATORS.

YOU'LL NOTE THAT THE KAC SR15 E3 UTILIZES KNIGHT'S OWN PECULIAR MID-LENGTH GAS SYSTEM, LONGER THAN THE "INDUSTRY STANDARD" MID-LENGTH. THIS I FELT WAS A LARGE PART OF THEIR SUCCESS. BUT THEY WANTED $39 EACH FOR THIS GAS TUBE ...

... SO WE TURNED TO ANOTHER PAIR OF INDUSTRY INNOVATORS, NOVESKE AND VLTOR, WHO CAME UP WITH THEIR OWN "INTERMEDIATE" LENGTH GAS SYSTEM FOR 18" SPR USE, WITHIN A FRACTION OF AN INCH OF THAT USED BY KNIGHT'S. IT IS #3 IN THE BELOW PHOTOS:





I TRIED THIS INTERMEDIATE LENGTH GAS SYSTEM IN 18" BUILDS AND FELT THAT IT OFFERED AN ACTUAL DECREASE IN THE QUALITIES WE WERE AFTER. IT FELT "CHOPPY" COMPARED TO THE RIFLE ELNGTH GAS SYSTEM IN AN 18" BUILD. BUT WHAT ABOUT IN A 16" UPPER?



TWO IDENTICAL UPPERS WERE BUILT UP WITH EACH OF THE NOVESKE BARRELS SHOWN, ONE WITH THE TRADITIONAL MID-LENGTH GAS SYSTEM, AND ONE WITH THE NEW INTERMEDIATE LENGTH. MATCHING NIGHTFORCE SCOPES WERE INSTALLED, AND A SIDE BY SIDE TEST WAS PERFORMED. BOTH SHOT EQUALLY WELL (0.60 MOA), BUT THE NEW GAS SYSTEM PRODUCED A "SMOOTHER" WEAPON WITH LESS APPARENT RECOIL.

WE ARE SO IMPRESSED WITH THIS NEW INTERMEDIATE LENGTH GAS SYSTEM IN THE 16" THAT WE'RE GOING TO MAKE IT A PART OF OUR FUTURE CUSTOM OFFERINGS. WE'RE EVEN GOING TO BE ABLE TO STEP DOWN ANOTHER SIZE ON THE GAS PORT.

GOOD SHOOTING,

WES GRANT

Unavoidable. It's been like this for years and its not likely to change soon.

Thanks for the report & pics Wes, good to see you posting.

Wes, very, very interested in this. I've got a 10.5 Noveske CQB barrel build that shoots amazingly (unbeleivably so) smooth with it's carbine length gas. I've also got a 14.5 Aghfan Noveske SS barrel build which is also extremely smooth with it's midlength gas. Noveske REALLY, REALLY knows their gas holes, so to speak. I've actually had a lengthy conversation with Joel about gas holes, ha.

I can only think that this intermediate length in a 16" (as opposed to the more norm 16" midlength) would be the same good thing I'm feeling my other two rifles. A sweet spot, if you will, between barrel length, gas tube length and of course the equally as important gas-port size diameter.
I think a Noveske Recon barrel in an intermediate length would be PERFECT. I ask why hasn't Noveske done this yet in a 16"? I would have to start a new build TODAY if I saw an int-length Recon or Rogue Hunter 16" 5.56 barrel pop up on their website.

What would a custom Recon barrel from you cost with a proper intermediate gas port & gas tube? Just bead blasted stainless. What's the ETA?

NO - NOT YET.

BUT, IF A D.I. GAS UPPER WILL RUN UNSUPPRESSED, IT WILL CERTAINLY RUN SUPPRESSED.

SUPPRESSED, IT DOESN'T MATTER IF A GUN IS DIRECT GAS OR PISTON DRIVEN. THE ENTIRE GUN IS GOING TO GET EXTRA DIRTY FROM THE GAS FLOWING AFT DOWN THE BARREL FROM THE SUPPRESSOR. THE ONLY THING THAT CAN HELP HERE ARE COATINGS THAT RESIST CARBON FOULING, E.G., IONBOND DIAMONDBLACK, ALONG WITH GOOD LUBE, E.G., GUNBUTTER.

Fixed it!:

"smooth" is good.

When you get to shoot as many different ar' configurations as paul and i do, the difference the little things make become more easily noticed and appreciated. We like our custom uppers to run "smoothly". It is a difficult quality to quantify. See new ar' guy's critique of our 6.8 spc upper several years ago on the uppers, lowers, etc., forum, where he comments at some length on this quality in our winning entry.

Another noteworthy example regarding this "smooth" running quality came from a special forces weapons guy who took one of our 10.5" guns on deployment to the rock box. He said in training up with the new weapon, he had to recalibrate his "feel" for the platform. In his words, "it feels like the bolt is closing on an empty chamber every time, when in fact it is feeding properly." he also reported confirmed hits on some "man-size" targets at 600 yd with it. Yes, it was a sub-moa 10.5". Maybe coincidental - but probably not.

A gun that runs more smoothly implies one that runs more reliably, more consistently, and with with better accuracy. Also, a shooter can run a smooth gun faster than one that has the typical "choppy" quality to it.

We place great emphasis on getting the best quality components built to the highest tolerances in our custom builds. This means "straighter" parts, producing less friction. Another critical aspect of a weapon's "smooth" qualities are optimum porting for the gas system, recoil spring, and buffer weight, as well as proper lubrication. The ionbond diamondblack coating on the bolt carrier group components that mstn pioneered also is a big contributor to this.

It is accepted as fact at this point in time that a mid-length gas system in a 14.5" to 16" barrel produces a smoother felt recoil pulse, less wear and tear on the weapon, as well as enhanced reliability than the original format carbine length gas system. Sound suppressor usage tends to greatly exacerbate these differences, too. As a result, we would never consider using a carbine length gas system in a custom 16" build. Mid-length has been the proven way to go in the 16" for some time now.

When the new knight's armament sr15 e3 hit the streets, i was most impressed with what an outstanding job they did in balancing the recoil spring and buffer with the gas pulse in their longer than standard mid-length gas system. This rifle is as smooth running as you can find, even at its ultra-light weight, and represents a tremendous value for the money. Wearing just a generic a2 flash hider, it produces less apparent recoil than some uppers with compensators.

You'll note that the kac sr15 e3 utilizes knight's own peculiar mid-length gas system, longer than the "industry standard" mid-length. This i felt was a large part of their success. But they wanted $39 each for this gas tube ...

... So we turned to another pair of industry innovators, noveske and vltor, who came up with their own "intermediate" length gas system for 18" spr use, within a fraction of an inch of that used by knight's. It is #3 in the below photos:

And at the end of the day we must remember that Stoner set the gas port where it belonged after considerable research for the barrel length and the new .223 cartridge characteristics.... Congratulations on your new work!
I wonder if there is a good correlation between 20" port placement, 18" port placement, 16" port placement (all with a specific port size) etc... some mathematical series. Personally, I doubt it because it is the same round and powder quantity which is "fully" consumed in a 20". Perhaps just empirical?

Wes, is it third from top or bottom? Longer or shorter than KAC? I've heard conflicting reports.

Also, if he could do light profile N4 barrels in this length...

IT'S THE THIRD LONGEST, 0.40" LONGER THAN THE KAC VARIETY.

I have always appreciated the manufacturers that ship barrels with a thread protector; I think they are essential. Not sure about the ones with the reservoir tip, but a thread protector is good to see.

I was looking for a 16" midlength, I may have to give one of these a try. What type of stainless are they made from?
