In this real steel video, Chairman Cat tries the Lee Sporting Lower to the Century Arms AP5P, an MP5K clone... "Thank you ‪@leesporting2132‬ for helping me acquire this mp5k lower without waiting for months. This lower is like a magical key, it unlocks the full potential of the MP5/MP5k platform, with SuperSafety installed the capability of this little package is shockingly good. As usual I will not go too deep into 'how', but only showcasing what's possible: LeeSporting lower + SuperSafety + Gessele SSAE trigger = burning a hole in my wallet."
