It might be from the same old AR15/M16 platform but I will tell you from first hand experience that this is a fine weapon. Single shot or FA it was accurate and comfortable.
The HK 416 is like having a old car and changing the engine out. It looks the same but runs a whole lot better because of the new guts that have been put inside of it.
Very Nice if I do say...
... Just my
(2 guns worth) though
