agwaldronNo trades STOCK: 3x Full-Size Semi-Shelf 3x K Push-Pin The Lee Sporting LS5 is the ergonomic upgrade your MP5 has been waiting for. This billet aluminum lower moves your firing hand 0.6" forward and 0.4" up toward the bore axis, transforming the dated MP5 grip geometry into a modern, AR-like feel — and it accepts AR-pattern fire control groups, opening the door to a genuinely great trigger pull on your roller-lock.
