Anybody have their AR accessorized for the sole purpose of home defense? If so, what is your rifle fitted with e.g. scopes, red dots, weapon lights etc. Lastly, when over penetration is a concern what is your choice of ammo, gr weight? Read somewhere on the "Net" that ammo for the sole purpose of dispatching varmint's should be considered for home use when over penetration of walls are a concern. Thanks. Just trying to get some ideas.. Yep, I am pretty much a Green Horn when it comes to this platform, totally a different animal when compared to pistols which I am well schooled on.
