Buddy of mine has one. He loves it, but also has buyers remorse. The B&T APC9 is a better choice by his own admission. HK MP5 of any variation was the world beater... in the 80s. Quality is never in question with HK, but theres lots of other options out there for lots less monies. His is a blast to shoot and has a stamp coming to SBR. My 2 cents.
