Lyman's Revolution® HD Gun Vise is just what the name implies, a 16 ½ pound heavy duty rotating vise for all your firearm maintenance needs. The Revolution HD Gun Vise starts with sturdy aluminum frames and center beam, along with stainless steel connecting rods. These critical metal parts give the vise the added strength and stability customers are looking for. The vise can be rotated 180 degrees and locked in position every 6 ½ degrees, which provides extreme versatility in positioning your firearm in just the right spot for cleaning or maintenance! The padded clamps offer 2” of height adjustment and can be positioned from 3” to 17” apart. The Revolution HD Gun Vise also features adjustable feet for a stable working platform on various surfaces. Plus, the Revolution HD Gun Vise comes with an MSR magwell support post which spreads to lock firmly into the firearm, preventing unwanted movement.
