So I'm very new to the AR game and I want one. I'm looking for a long range toy in 556. Target and varmint shooting. Would a Rainier RUC FDE Lower and a rock river 24" stainless upper 1-8twist be a good match for wht I'm wanting to do? Would like to shoot 3/4"-1/2" moa or better. Would like to keep the price under 1200$.
