With PH being an accepted USMC optic, does the PH need a new cap or will the S&B model work. This is not meant as a CLONE WAR thread, but I am trying to get my M40A3 approved for duty use. We already have Simrads but they are on 30MM leupolds. I'm gonna try a PH first before an S&B, I like the features better for now. Jeff
