33* offset does not fit all acogs - American Defense Manufacturing AD-RMR Offset Mount

Would I recommend this product? Not for someone who has a TA01 variant of the ACOG (the 4x magnifier without fiber optic). Otherwise, I would say that this part is of excellent quality.

My Acog is a 4x32 with crosshairs and tritium without the fiberoptic solar powered chevron that many have. I wanted a left-handed offset mount for my trijicon RMR, and I intended to mount it close-up, under the ocular lens (shooter's side) of the Acog. I decided on this product with the 33* angle, because the summary description says that it was specifically designed for the ACOG. However, I can attest that this does NOT fit under the shooter's side of the acog. The mount makes contact with the acog's ocular lens fastener bosses and will not secure properly to the picatinny rail as a result. It will fit under the objective lens. I've reordered the same product, except with a 45* offset hoping that it will fit as desired. Hopefully, the 45* mount will fit without any contact and allow the RMR to be mounted on the shooter's side of the acog.

On the objective side of the scope, the lever is pretty long and therefore prevents the RMR from being mounted as close as possible to the ACOG mount.

I tried grinding down the part of the mount that was interfering with the ACOG bosses, but there are 2 problems with that. First, it would also require grinding into the RMR itself, which does not have the room to be ground down. Second, any hope of waterproofing the RMR is gone with this approach as I had to grind down the mount past the seal on the RMR. Having said that, I've ordered a Trijicon RM63 sealing plate, which should restore waterproofing to the optic. Finally, I ground down the lever on the mount and can now mount it on the closest possible portion of the picatinny rail.

I'll be back with a review of the 45* offset.
