You're correct Steve. I measured my Z shaft and it was .842.5
Measured my wife's Predator wood to wood at the butt and it was .842
My 314 is a partial so measures under, whoever turned it. .839. Small lip at the joint collar depending what butt I use it on.
Thanks for the info.
I was pretty sure it was .842___
but didn't want to assume incorrectly.
That seems to be a popular number with predator. Could be the tie in
with uni-loc.
