Ive nothing against them personaly, and for the range i think they are perfectly acceptable, and in some ways look quite good, but its not worth the risk of taking it out after quary, if someone sees someone walking round with a standard rifle, they will more than likely understand the purpose but if they see you with what looks like a military weapon, i'm sure they would be straight onto the old bill more hassel than its worth imo.
