Well made but too expensive - Trijicon 45 Rail Offset Adapter For Rmr

This offset adapter is the only model I could find that places the red dot in correct position to clear the tall tactical scope knob on my AR. This offset rail is well made and clamps tightly to the handguard. However, I have a couple different models of this type of adapter from different manufacturers, and while they didn't work well for this particular application, seem to be just as well made. The others cost less than 1/4 the price of the Trijicon model. This is just another example of paying an exorbitant price for a brand name. I deducted 2 stars for the excessive price.
