bore

Thoroughly spray all the carbon-coated surfaces of the muzzle brake and bore evacuator with CLP, NSN 9150-01-054-6453.

Then, lightly lube the inside, valve balls, valve ring and all unpainted surfaces on the bore evacuator.

Reassemble the muzzle brake and bore evacuator following the instructions in the operator's manuals.

Intended to replace free extrusion with a vacuum-tank system that fits within a clean-room environment, the all-stainless Micro Bore ships on a single base measuring only 7.5 ft long.

A fine-toothed timing belt containing a non-stretching stainless-steel braid drives the Micro Bore's integrated puller, and a built-in Thermolator water-temperature controller from Conair Tempro completes the equipment package.
