piggybacking an ACRO on an ACOG?

[RAM Engineer]

Does anyone make a mount to piggyback an ACRO (P2, specifically) on an ACOG, using those RMR bosses cast into the housing?

Those bosses cast into the body of the ACOG are to accept an RMR footprint mount. Not for direct mounting.

Trijicon also makes an RMR mount for ACOGs without the cast in bosses.

Either way, they only way to do this at this time is ACOG RMR mount then use the RMR footprint to ACRO footprint adapter plate from primary machine or Aimpoint.

The bosses are just circular lugs on either side of the eyepiece. The RMR mounts that are commonly seen are half-rings that bolt to either side with an RMR mount on top. I see what you are saying, but I was wondering if there were any ACRO mounts already made that bolt to the bosses. Sounds like no, so my only options are those you gave me.

I don’t know of anyone who makes mounts for those bosses other than Trjicon.
