I have purchased a Bushmaster M4 A2 assault rifle and I have bought rubber rounds for it. Can I use it to patrol my neighborhood at night? We have ALLOT of druggies on meth, PCP, and heroin. In the past two weeks we have had 5 break in's and robberies. One of the neighbor's is in the hospital for getting shot in the shoulder so they are armed and dangerous. Dont say anything about cops cause the guys are like hydra take one down two more pop up.
