The Bushy I am buying through my Dept. is a 16" m4, a3, four position collapsing stock, Phantom supresor, 30 rd mags ect. I could only get this setup through my dept. I was told by our armorer that individual officers could purchas them if they had a minimum 16" brl and were semi only. The officer has to be employed full time at the time of purchase. Now if I leave law enforcement I can take the gun with me. Hope this helps.
