Some confusion on the lengths. I measured mine again and they are still as I published, but the Kaw Valley website shows 2 1/8" Visual comparison shows they have made some changes from when they were first sold. I bought both of mine on the roll out version initially sold by Joe Bobs for $32. They appear to be shorter than the current version with more of an extension around the flats area. This is good, because a normal wrench did not fit well and I had to use a “skinny” wrench to tighten. As for length, I would use the 2 1/8" published by Kaw Valley http://kawvalleyprecision.com/kawvalleyprecisioncomp.php
I have bought 2 from Joebobs in the past couple months. This is the latest one on my 300blk pistol and it physically measures 2.075" x 0.950". I don’t use a crush washer when installing linear comps, that would add a bit more to the OAL if installed.

Interesting. I’ve only taken my rifle out once with my KVP comp and it seemed to move my mid-length ejection backwards, from 3 to about 4.30. Admittedly, I did go from using XM-193 to PMC Bronze.
Clearly more testing is required. Guess I’ll have to hit the range again. Shucks. :-7

Two variables introduced: Change in comp and the use of lower powered PMC ammo (223 to boot). Can’t fix the cause on one or the other.
Use XM-193 next time to see if there is any change.
