I can tell you I am very excited about getting one an MR1 once the boss (aka The Wife) lets me. (its gonna be negotiated, she will get a new toy of her own).
I am not a fan of the AR-15 platform, and I say that with 14 years of military experience with them, so I was happy when I dicovered the MR1.
The only thing that could make it better would be a 6.8mm version.
Does anyone know if Benelli is even considering it?
Will likely get the current version in any case, but if the larger caliber is coming, I would want one.
