Much better than the factory stock - Kinetic Development Group Kinetic Scar Adaptable Stock Kit

Overall, the stock looks and feels like a better quality product than what comes out of the factory. Adjustments to the length of pull and the cheek piece are smooth to adjust and solid when set. The KDG stock does not rattle or feel loose like the factory stock. Replacing the old stock with the new one was very easy. The tolerance with the metal back plate of the KDG stock provide a secure fit the the upper and lower receiver. Do some reading on this product before you purchase, as there are other reviews indicating that the metal back plate creates undue stress on the screws in the rear of the upper receiver from the recoil of the weapon. I use a precision armament .30 caliber muzzle brake and have not noticed any issues.
