picked up my POF MP5K today. got to shoot it too.
I like it a bunch. It shoot really softly.
I went ahead and filed my form 1. Also ordered a 4 position collapsible stock, the vertical foregrip front end and an extended charging handle for it.
I may replace the tirgger pack with a navy trigger, but not until i shoot it a bunch more. it is WAY too easy to chip through a mag with it.
it is gonna be awesome once my stamp comes back!
