I am working on gathering parts for a 3-gun upper. I have a BHW 18' rifle lengh barrel....
•Caliber: 5.56x45mm (NATO) •Barrel Length: 18" H-Bar Profile •Gas System: Rifle-Length •Barrel Material: 416 Stainless Steel •Barrel Finish: Matte Black •Rifling: 1:8 Polygonal 3 groove •M4 feed ramp is included •Under Handguard: 0.88 inches •In front of gas block: 0.73 inches •Threading (TPI): 1/2x28" •Weight: 2.2lbs •Magnetic particle inspections and other non-destructive testing performed on barrels by manufacturer. I am thinking about sending it in to be lightened up. What is a better option: fluting or a lighter contour? What contour? |
Thanks fellas.
