The build quality, as always with Magpul, is top-notch. I previously had the stock buttstock and it didn't suit me—too little adjustment. This one has everything I would expect from a stock: a wide range of length and cheek rest adjustment, great design, and it's easy to get into shooting position. The only drawback I've noticed is that the rifle is now significantly longer than with the old stock and doesn't fit in the case, so you either have to disassemble your AR into two parts or invest in a new case. Still, for shooting at longer distances, I highly recommend it.
