luger ::uprkos wella coloursu diemaco je u pravu,
enfield i matford su dva nacina zljebljenja puske sistema lee...
Ma naravno da sam u pravu
luger ::ono nije poligon kakav danas smatramo u poligon,e tu postovana diemaco
nisi u pravu...smatraj ono matford zljebljenjem...da ne ulazimo opet u pricu...
Dragi moj Guy Montag, naravno da sam i ovde savrsheno u pravu jer se u vreme Metford pushaka takvo zlebljenje smatralo polygonalnim. Inache, na engleskom jeziku rec rifling oznacava zlebljenje. Polygonal rifling je poligonalno zlebljenje.
Danas je to shirok pojam Guy. I danas mnogi proizvodjaci imaju sirok dijapazon poligonalnih profila cevi. Chak i neki proizvodjaci, cije je zlebljenje cevi vise klasichno, ipak upotrebljavaju termin poligonalno zlebljenje. Hvala.

Citat:While polygonal rifling has been around since the earliest days of rifled barrels, it had faded out of use by the time of the early cordite cartridges. The last common rifle to use polygonal rifling was the Lee-Metford rifle, named after the Metford rifling, a seven sided polygonal type rifling. The switch to cordite from black powder proved too much for the shallow rifling in the relatively soft barrels of the time, and the Lee-Metford became the Lee-Enfield when the Metford rifling was dropped. Heckler & Koch was the first manufacturer to begin using polygonal rifling in modern arms. Companies that utilize this method today include Heckler & Koch, Glock, Magnum Research, Česká Zbrojovka and Kahr Arms. Polygonal rifling is usually found only in pistol barrels, and is less common in rifles, However some extremely high end rifles like the Heckler & Koch PSG-1 or the Mexican FX-05 rifles use polygonal bores.
The term "polygonal rifling" is fairly general, and different manufacturers employ varying polygonal rifling profiles. H&K, CZ and Glock use a female type of polygonal rifling similar to the bore shown above right. This type has a smaller bore area than the male type of polygonal rifling designed and used by Lothar Walther. Other companies such as Noveske(Pac Nor) and LWRC use a rifling more like the conventional rifling with both of the lands sides being sloped but has a flat top and defined corners, this type of rifling is more of a canted land type of rifling than polygonal rifling.
