Until the gas gets to the outside of the case, the case is a pressure vessel, imperfectly supported by the chamber.<br /><br />Another approach different than the fluted chamber would be a chamber that moves back with the case and bolt until the pressure drops. That would add mechanical complexity.Don Mhttps://www.blogger.com/profile/06057058763094040058noreply@blogger.comtag:blogger.com,1999:blog-9038805453913133808.post-18115363868586896942016-01-12T09:57:04.909-08:002016-01-12T09:57:04.909-08:00The main drawback is the same that applies to much...The main drawback is the same that applies to much more popular roller-delayed blowback: the extraction starts while the case is still expanded. This causes difficulties with extraction. Obviously it's not insurmountable, even on a main battle rifle such as G3. Still, quality ammunition is required least you get a case neck separation or even plain failure to extract. A fluted chamber ameliorates these issues.ザイツェヴhttps://www.blogger.com/profile/17164033061112816744noreply@blogger.comtag:blogger.com,1999:blog-9038805453913133808.post-10189972068880012752015-10-07T10:08:59.351-07:002015-10-07T10:08:59.351-07:00What is the drawback of this system?
surely there ...What is the drawback of this system?<br />surely there must be some limitation that heavily hinders its military usefulness<br />otherwise most modern rifles wouldn't utilize gas operation instead 異視點https://www.blogger.com/profile/16641170500568025072noreply@blogger.com
