Bolt heads have three radial locking lugs. The rotating bolt locks into battery via two locking lugs. The manually operated bolt action has a rotating bolt with three symmetrically-spaced frontal lugs. These three locking lugs also greatly increase bolt strength. The barrel is locked using a rotary bolt with multiple lugs. The bolt was far sturdier and had multi-thread locking lugs. Flanges, trunnions, clevises, and lugs are common cylinder mounting options. Other terminations were binding posts, terminal strips, and spade lugs for crimp connections. The bolt is linked to the slide via one of the bolt lugs. The gas cylinder, support structures, brackets, lugs and other devices are welded in place. The bolt travel is also reduced because of the rear lugs. It holds the steel bearings for the barrel lugs and the guide rods. Weatherby designed the action type with nine locking lugs arranged in three rows. It is a manually operated bolt action with two forward dual-opposed lugs. The bolt has nine lugs in three rows of three lugs each.
