[QUOTE="orkan, post: 2587928, member: 25377"] Not to mention the actual force of bolt lift for equal pin fall will be much lighter in the 90° without sacrificing ignition spring rate, as the cocking cam on the bolt body is steeper for the same linear pin travel on a 60° than a 90°. This makes it much easier to not violate NPA during the bolt cycle. These reasons among many others, is why I only recommend 90° actions such as Lone Peak Fuzion and BAT TR fully integral and nitrided actions. ----------- [URL='https://www.instagram.com/primalrights']Follow on Instagram[/URL] [URL='https://www.youtube.com/user/primalrights']Subscribe on YouTube[/URL] [URL='https://amzn.to/3txlBnp']Amazon Affiliate[/URL] [URL='http://www.primalrights.com'][IMG]http://primalrights.com/images/signatures/sig1.jpg[/IMG][/URL] [/QUOTE]
