ONE HORSE UPPER PARTS KIT – DUST COVER AND FORWARD ASSIST

Description

The One Horse Upper Parts Kit is an ejection port dust cover.

The dust cover closes the ejection port when the rifle is not firing, keeping dirt, sand and lint out of the upper receiver and off the bolt carrier. It springs open on the first shot and stays open.

It is a wear part more than a precision one: the spring tires, the pin walks, and a cover that will not stay latched is a cheap fix rather than a gunsmithing job. Mil-spec ejection ports are a common standard, so a mil-spec cover fits most AR-pattern uppers – check yours if the receiver is a proprietary shape.

This is a part or accessory, not a firearm, and ships directly to your address.
