These fit the forend screw holes and eliminate the damaging star washers and flat
washer OEM setup. You receive two washers- one for each side.
No other spacers or washers required. Helps eliminate screws from
hitting the detent sledge in the receiver and stopping the screw from bottoming out.
Black- rust free.
Will fit other 5mm screws like HW etc. On those if the stock is new with no compression
these are a few thousands too high. But any used stock they should flush out fine.
