4 of my own so far and another on the way. (and a few others for shooting buddies and even sold a couple more)
Whiden V Block in the last one and just got another V Block in the mail for an SP rear grip build in .204 Ruger.
The Whiden V Block makes all the difference in the world. No worries about the crappy inlet that you may get in the Micro Fit stocks.
Know ahead of time that you'll have to do some work to get their stocks ready to finish and they're a good deal with a good selections of designs.
Long wait times to get one but that's expected. IMHO, Well worth the wait. ;D
