Hi,
I recently got a 2012 version of 416. I like to express my impression about vfc 416 after spenting 4000 BBs.
Luckily, I don't have any issue with the BCG yet. (Plz, note that I used 134a insteed of the propane due to a power limit-under 300 fps- in Korea.) I think the vfc have made a great improvement regarding faulty layout and pot metal internals exept a steel bolt catch.
However, you can achieve better performance and durability by altering your habit and some cheap part.
First of all, never push the bot catch when reloading a new mag becaue a steel bolt stop tear down BCG
