Hi, I'm trying to decide on which barrel to use for standard military ammo such as 55gr M193 and 62gr M855. I've been told recently that the Sionics 1:8 16" BB barrel is a solid choice as the 1:8 twist rate can theoretically stabilize 55gr and 62gr ammo better than its 1:7 twist counterpart. However, tipping the scales at 29 ounces, it's not exactly a light barrel. The meaty profile may better help with heat dissipation but only at the cost of maneuverability. Other well known and highly touted options are the Daniel Defense CHF lightweight barrel (24 ounces) and the Centurion CHF lightweight barrel (26.9 ounces). Though these barrels fully twist every 7 inches, the reports are that they shoot the lighter grain stuff every bit as accurately as the 1:8 and 1:9's. The only drawback to choosing either of these CHF barrels is the price (Sionics 16" retails $190; DD 16" retails $289; Centurion 16" retails $325).
With all the barrel configurations and flavors out there, from CHF vs BB to 1:7 vs 1:8, which barrel is the best value pick for combat applications (running and gunning) when mostly using standard military ammo (M193 & M855), and occasionally your 69gr or 77gr SMK's?
