No, I have the correct mount. Their website agrees with my assessment. They are simply 1 size off. Here is a quote:
The Aimpoint Micro T1 High Mount provides a 1.7″ height riser which is .20″ over a Lower 1⁄3rd co-witness when mounted on the AR15/M16 weapon platform.
Thank you for the heads up, I’ll be ordering my first Bobro Aimpoint micro mount within a few weeks. I would have been very disappointed had I bought a 1/3 lower to find out it was really absolute. Why on earth do they mislabel them?
I have no idea, but here is a picture someone else took. The mounts are all listed as “Lower 1/3” by their manufacturers except for the ADM, which is listed as “Absolute”. You can see that the Bobro is ALLLLLMMOOOSSTTTT as low, in “lower 1/3” format, as the “Absolute” ADM, and significantly lower than the LaRue “Lower 1/3”, and ADM “Lower 1/3”.
This disparity was brought to my attention because I have a Bobro “Absolute” co-witness which does not line up like it should with my G33 magnifier without the G33’s spacer. I was under the impression it should line up perfectly, and when it didn’t, I went to Google, and found the data I’ve presented in this thread. Now, I don’t mind, as I didn’t buy the G33 for this rifle, and I have a GDI Absolute co-witness on my T2, which will be run with the G33, but I still wanted to present this info for others who might be rather non-plused about it.
The Samson RAM Micro Aimpoint mounts are the same. Their “lower 1/3” is 1.5" and their “tall” is 1.7". I found out the same way you did, buy buying a Samson lower 1/3 and realizing it was shorter than some of my other lower 1/3 mounts when it didn’t line up correctly with a magnifier.
