Is this H&K licensed production or another shameless knock-off?
Just read this:
No, they are NOT made under license from HK. NORINCO does NOT appear on the list of approved HK licensees. These NP08s are REVERSE-ENGINEERED copies of the MP5A4. Reverse-engineered, meaning they got a real german MP5, made measurements, try to approximate the quality of the material use, and made 'em.
