[Best M4 choice for beginners]

My pal and I were thinking about getting something along the line of a "cybergun - colt m4" for out first step into the field..

However, I'm still split about which one to buy, with the best choices at the moment being the:

 

-M4 silent ops (metal except for stock)

-M4 silent ops (=full metal (+20€))

-M4 hawkeye (full metal)

 

I'lI just throw these choices out there since our coupon code is running out rather soon

 

Thanks Guys
