With three Magwell configurations to choose from, Lancer Systems' L15 lower can be rapidly customized for a specific mission, trip to the range or three-gun match. The tactical and competition Magwells have a large smooth funnel like internal surface to facilitate rapid magazine changes. The standard size Magwell emulates the size of a typical AR lower. The Magwells attach to the lower via a captured rail and locks into place with a standard front takedown pin. The use of the takedown pin allows the Magwells to be removed without the use of special tools. The Magwells are precision machined from aluminum billet to match the features in the lower, ensuring there is no rattle during operation. The lower also features an ambidextrous bolt release and oversized magazine release button. The L15 lower is available stripped or complete with various trigger and magazine well options.
