In a time of trying to improve on an already great design (AR), has any major companied come up with an improved locking mechanism for the upper and lower receivers with the added improvement of making the take down process or mating process much faster?
Obv this would lead to a proprietary design but I feel that when quickly trying to assemble an upper and lower receiver, the take down pins leave much to be desired..
