I was curious if anyone had experience with the ballistic advantage 18" .223 Wylde SPR Fluted Stainless Steel Rifle Length AR 15 Barrel, Premium Series? http://ballisticadvantage.com/18-inch-223-wylde-spr-fluted-mid-length-ss-premium-barrel.html I am intrigued by the weight , price(on sale) and sub Moa guarantee but am concerned about how well a barrel of that weight will hold up to prolonged and rapid firing. I'm a total noob and have spent weeks reading up on barrels and options and recognize there is no perfect option but was hoping that I could get some guidance on why this may be a bad way to go. Thank you everyone !
