I got a great deal on a AR last year $600.00 .It's a Stag lower and upper with a DPMS stainless 16" bull barrel .223 1:9 twist. I'am wanting something for plinking and when the SHTF chambered in 5.56 .leaning toward a 1:8 twist ? suggestions on that would be appreciated. I've been thinking about a Daneil Defense Barrel any thoughts on those ? and thoughts on a cold hammer forged barrel ? Open to suggestions on other brands . looking to spend no more than $ 300.00 .All suggestionns would be apprectiated .
