Thanks for the link to the guide. I wasn’t aware there was anything out there with pics. I did end up picking up a Raptor this week online. I installed and it and it dropped right in and seems to run fine. I haven’t shot it with it yet but did cycle several mags of ammo through it for testing with no issues. I purchased my M&P 10 the summer of 2020 new in the box, so it is a newer production I assume. I did file off the step on the top of the charging handle as some had mentioned doing in other posts I saw about using the Raptor with the M&P10. It didn’t seem like I would have needed to, but I decided to anyways since the factory charging handle is flat across the top and didn’t have the step. I will have to check for the step in the trough leading to the hole as I didn’t take notice to that or see it mentioned about filing that area down. Thanks again.
