I have been looking at AR18 prints and SCAR receivers and am kind of puzzled by the bolt cam pin guide. What exactly is its purpose? Is it just to give a standoff from the pin slamming the receiver or does it aid in the rotation of the bolt? Being the AR15 has a similar bolt but no guide, I can't see why its needed.
