Mine so far has been awesome. About 600 rounds down the pipe of all different sorts of ammo and have had no issues with it. Mine is a mini 30 but same stock. Nothing loosens off. And my red dot holds zero no problem. The whole top rail comes off via 4 Allen head bolts and can only go back into the same position. Stock is for sure heavier than the ruger stock but the feel and quality are great. Nothing is loose and everything fits snug. If your thinking of getting one do it you won't be disappointed
