Has anyone come across a good YouTube video on how to install the NPAS in an OB Scar. I found a pictorial write-up and it references cutting something off the valve spring but its not clear on exactly what to cut. I'm thinking that its the little curly tail on the end of the spring. Can anyone confirm this? Also, the pictorial says not to trim the prongs but other sources say to trim. I believe that trimming the prongs is supposed to allow extra space for the new valve to move within to increase the range of fps settings. Anyone know for sure whether the tabs have to be cut and how much? A good video would really help. Anyone who has done the conversion interested in walking us noobs through it? Thanks for any help. Link to pictorial instructions below. Sorry, not sure if this will end up being an active link or just text but I suppose you can copy and paste into browser window.
