I finally got the funds for a AR,used for varmints,deer and HD.I have narrowed it down between the coyote carbine 16in 1x9twist and a A4 varmint 18in 1x8 twist,I will order either one with the RRA A2 stock,houge grip and free float tube,and the chromed bolt carrier group,after that I don't know because I am a bolt gun guy.I know that you can get different charging handles,mag catches,ect..that is why I am askin for your info,advise any would help.
