OH that is good to know...thank you!

Hi All, I've got a very nice HK Marked M1S90 Tactical that I'd like to modernize ever so slightly with a scalarworks low profile RDS mount that will cowitness with the ghost ring irons. However the M1S90 is not drilled/tapped for mounts whereas the M2 is. Was wondering if there was a hole template out there for drilling in the factory locations? I believe the m1 and m2 receivers are identical, so there should be no issue drilling it, just want to be sure they're in the right spots. Pic for attention. (Pictured is an M2 but my M1 is setup exactly like it minus the RDS)

Just checking back in here to see if anybody has any thoughts??

I'm new to the forums but not new to Benelli. Recently picked up an 1995 production m1super90 in unfired condition. It has the raised tactical ghost ring sights and the smooth rounded top receiver. I am looking to put a RIS rail on it to mimic the m4 super 90 and was wondering if there were any that could be recommended. Im planning to get a low profile red dot to co-witness so id need some low rise RIS rails. Yankee hill makes some that I found somebody said they used. I realize I'll have to have the top drilled and tapped. If there's a factory option, or a generally accepted way of doing this I'd love to hear about it!
