In the spirit of MP5, I'm changing my setup for usability. I swapped the HK A3F stock for a B&T folder and my trijicon mro for a Leupold LCO. She's Also rocking the KAC handguard setup that I'll be swapping for a MI M-lok as soon as fedex un-looses it. The balance difference is phenomenal with just the stock swap. ( removed parts are not for sale.)
