Basically "Hipster" form Rifling, lol. From the Wikipedia page on it:
A number of advantages are claimed by the supporters of polygonal rifling. These include:
Not compromising the barrel's thickness in the area of each groove as with traditional rifling. Providing a better gas seal around the projectile as polygonal bores tend to have a slightly smaller bore area, which translates into more efficient use of the combustion gases trapped behind the bullet,[4] slightly greater (consistency in) muzzle velocities and slightly increased accuracy.[1] Less bullet deformation, resulting in reduced drag on the bullet when traveling through the barrel which helps to increase muzzle velocity. Reduced buildup of copper or lead within the barrel which results in easier maintenance characteristics. Less sensitive to stress concentration induced barrel failure. Prolonged barrel life.
I've honestly never heard of it but now I'm intrigued and have some questions. How long has it been around? Has there been extensive studies showing the comparison between the two? As for now I feel as if it's a meme and their trying to fix something that isn't broken.

Complete bullshit. Polygonal rifling was invented decades before jacketed bullets and did just fine.
Lincoln White
Seriously? It is fairly widespread.
Justin Harris
Uh, what is the Whitworth Rifle? It's the gun that killed multiple Union Generals from great distances.
Carter Brooks
>1st sniper rifle >1854 >polygonal rifling >ff 2019 zoomers call it hipster and say cant shoot lead
Nolan Martin
Yeah man, never heard of it. From it's been a while for a long ass time. Why did they move away from it if it was superior? Modern advances in the way it's machined?
Elijah Howard
It's a meme, rifles were grouping sub MOA in 1853 with the whitworth rifle.
Matthew Kelly
It's been in near continuous use for 150+ years. Britian and Japan both used it in military rifles. It's actually ridiculously easy to make with hammer forging.
Jason Price
It was an elegant weapon technique for a more civilized age.
Oliver Sullivan
So, would this work on a tank barrel?
Isaac Lopez
>rifles were grouping sub MOA in 1853 with the whitworth rifle 1854 and they didn't shoot sub moa.
Maybe they just can't Polygon and don't want to admit the technique is beyond their gun-making abilities?
I dare them to make new models.
Anthony Foster
Seriously, I bet they can't do it anymore.
Ryder Powell
>I own two. 19, 22. I've honestly still never heard if it till now Literally in their marketing all the time. Shit they touted that it allowed their barrels to last longer than the rest on a few ads
Robert Reyes
My guess is it was to get customers in who were scared of the hard cast bullets will rekt your glock meme. That or the tooling for their barrel making machines wore out and when it came to buy new it was cheaper/easier to go traditional. Hell maybe it just saves money. Poly rifling isn't some dark art

It was found unsuitable for early smokeless powder (especially cordite), so it fell almost completely out of use around the turn of the century. The problem was cordite burned barrel throats up quick, and polygonal rifling quickly erodes straight to round, whereas sharp-flanked rifling erodes into something like polygonal rifling first, and thus lasts longer. Thus the sharp-flanked "Enfield" rifling pattern displaced the "Metford" pattern in British service, pic related.
With modern powder (less erosive) and metallurgy (more resistant to erosion), this hasn't been a problem for a long time. At this point, polygonal's fine, sharp flanks are fine, "5R" and similar rifling patterns that more or less split the difference are fine. None of them has a decisive advantage, really, though various rifling patterns are more suited to specific production methods.
Modern gunmakers are curiously adverse to experimentation. They rack in tons of cash, yet somehow can't afford to try out "new" (i.e older but proven) tech for the modern age?
MEH.
Ethan Hall
I'm honestly curious to see how a modern polygon gun would stack up, for the novelty value alone.
Ryder Howard
Glock has been using polygonal rifling since gen1 til gen4 dipshit. HK used it some handguns and quite a few others as well. Why do you retards keep acting like it's a lost art?
Connor Edwards
Glocks? HKs? Walthers? Deagles? There's plenty of them, and they stack up just fine.
Isaiah Perry
I don't know. I must consult the ancient scrolls and sacred texts.
Serious answer: I think people are under the impression Polygonal rifling is forgotten.
Nathan Scott
Almost all euro guns use polygonal rifling FN, HK, Glock, Beretta, CZ, Steyr, etc This isn't ancient technology or some modern marvel. It's been used all the damn time. If anything, US gunmakers are the oddballs use "traditional" rifling. Ruger however, uses polygonal rifling in almost all their guns.
