Lungime teava interna

Recommended Posts

Salutare. Am un ics m4 splitgearbox si mam gandit sa imi fac un upper pentru categoria DMR, mi-am comandat un kit bore up http://www.icsbb.com/product/ma-56-upgrade-upper-gearbox-f/, si acum problema mea e: care este lungimea maxima sau optima a tevii interne ca sa am un range cat mai mare, mi sa recomandat un prometheus de 455, dat acum va intreb pe voi, voi ce lungimi aveti la tevi si oare daca imi pun una mai lunga poate umpic peste 500mm, mai castig ceva?

Nu. Mergi pe o lungime de 450-470 mm. Am probat destule. Peste 470 mm nu duce cilindrul de aeg standard. Am un SVD, are cilindrul cu 2 cm mai lung, duce o teava de 600. Insa, din orice am probat, peste 470 mm s-a dus naibii precizia.
