The Little Crow Gunworks AR-15 Trigger Guard Roll Pin Pusher is an ingenious device that makes swapping or installing a new trigger guard a quick and easy process. Since the tool slowly pushes the trigger guard roll pin in or out of its channel, there is no more fear of breaking off a lower receiver "ear" due to insufficient support while hammering in a roll pin. This durable tool is constructed of aluminum and steel, with a 1-5/8" thermoplastic ball handle.
