I would much perfer the AR10,7.62mm rifle better.It is small enough to be carried in the vehicle, and the officers are already familar with the weapon type. This is just one former Marine's thought, being respectfully submitted.
My son just finished his post Afghanistan deployment leave. He has money burning a hole in his pocket and left me instructions to order him an AR10-TN or TBN tomorrow. When it comes in I am to take it to Krieger Barrels and have them put on one of their accurized barrels. He'll end up with about 3 grand in the weapon and probably another grand in accessories.
I'm jealous.
