I'd buy it again, price was right for what I wanted, my hand guard was centered, mine groups better than I can shoot, the stock works for me and if you actually read the instructions on adjustment you can see the riser lever needs to be turned to adjust and when in the right position for locking it takes little effort and no reason to be forced or over stressed causing failure, settings of the stock also need to be positioned in the correct notch before lock down.
Most of the online reviews #####ing about the stock that I've seen the guy didn't know how to properly use it, guys complaining about the riser position and in the manual tells you it can be reversed if needed, or guys pulling and forcing the parts not turning the lever 1/2 turn, or complaining the adjustment moves because they are trying to lock stuff down between the notches.
People are welcome to dislike what they want and buy or sell what they don't like or want, but at least properly operate something before trashing it.
My comments are not directed towards anybody in this thread, just my observations of some online reviews I've seen, and I'm glad I didn't let them effect my decision to buy one.
