[m4 vs m1014?]

I'm new to benelli and could use some help. I'm trying to find an m4 for a gift but i'm confused by the m1014. what's the difference? is it just the stock? anyone know where I can get an m4?

 

thank you

[Price on M1014]

I'm new to benelli and i could use some help. My dad's birthday is coming up and he'd like the m4. What is the difference between the m4 and m1014? Is just the stock? Know where i might get an m4?

 

Thank you
