Not a precision stock due to poor fit - FAB Defense R.A.P.S - Rapid Adjustment Precision Stock - Collapsible

Unfortunately the fit of this stock is unacceptable at least on a mil spec size buffer tube. Yes, the tightening skrew helps make the stock not rattle however when fully extended the stock still cants depending on your grip pressure. Meaning: if you hold the front of the rifle with your hand and pull the stock into your shoulder you can move your trigger hand to move the grip up moving the barrel down or pull down moving the barrell up. So essentially with every shot the recoil could move your sight picture. I wouldn't want this on a general blinking g rifle let alone one intending to be a precision set up as the stock is intended. I plan on returning.
