That Tarantula has one of my custom shrouds I custom machined back in 2009. I polished the 6061 Aluminum and had them black anodized with brite dip to match the factory finish. I always thought the factory shroud didn't look right as they were made from steel. This also eliminated the 1\2 x 20 barrel adapter on the barrel as the end cap had the male threads integral, really made the gun look even better.Somthing is different with that rifle. The barrel is longer ?
