Re: KMW Sentinel stock
I'll be the voice of dissent, I really really really wanted one a couple years ago and was able to get behind one and found it actually wasn't for me.
This can be said of any stock design, so the advice to get behind one of whatever you are considering prior to ordering is sage advice indeed.
I know guys that have shot a stock model for years that thought they loved it until they tried something else. It would behoove you to mock something up and find what LOP works for you, and if you will need an adj cheek, no matter what stock you wind up getting....the right stock with the wrong fit will compromise the endeavor no matter what.
