Just make sure you spit real hard ........ I imagine baky-juice and rotar downdraft could get kinda messy.
p.s. Have you shot an AR yet??????? I got to get me one (but something bigger than .223). The spring in the stock takes a little getting used to when you shoot it, but eventually you never notice it. I took Dad's, in .223, on a hog hunt last winter after some small hogs and piglets ...... reloaded Hornady Vmax bullets do a number on small hogs
I still prefer to shoot them with the bow
p.s. Have you seen the Night-hunts with night scopes for hogs????? Google/uTube that
