I have just discovered DB guns yesterday by doing Google research on AR rifles currently in production. This is an AR type whole line of guns available in 5.56, 6.5 CM, .308 and .300 Blackout. Some of these rifles boast MOA accuracy out of the box according to some sources.I do like the fit and finish of these firearms by the look of them in the pictures. AR-platform guns by Diamondback Firearms look pretty to me and they are not too expensive for me and that's why I find them so appealing right now.

Is there one single caliber available in any AR-based rifle retailing under $1,000 that is practical, economical and effective for both deer hunting AND small rodents?

PS If a round of ammo is over .50 cents a shot, it seems too expensive for me to be shooting gophers with it. I don't mind spending up to $2 a shot to kill a deer however. Deer are prestigious game, rats are nasty pests.
