Weapon Outfitters KRAM Optic Spacer - ACOG Pattern - 9.0 - Black
All versions of the KRAM (i.e., the KRAM 5.5, the KRAM 7.0, and the KRAM 9.0) are compatible with all ACOG mounts made by various manufacturers.
That is, it doesn't matter which particular ACOG mount you are using - all the variations of the KRAM will "work."
The only question is how much you need, or want, the ACOG to be raised (e.g., in order to clear the rear flip sight).
For example, if the particular ACOG mount you are using raises the ACOG 4 millimeters off the rail on the upper receiver, and your flip sight is 11 millimeters high (when folded down), you need the ACOG to be raised an additional 7 millimeters in order for the base of the ACOG to clear the flip sight. In this case, the KRAM 7.0 will probably work for you.
AS A GENERAL RULE OF THUMB (results vary depending on what base mount you are using):
- The "5.5" model works for very thin rear sights, such as the MBUS Pro
- The "7.0" model works with most rear sights, and results in a height similar to 1/3 cowitness mounts for red dots.
- The "9.0" works with the thickest rear sights, such as the Polymer Magpul MBUS
