The Pro-Shot Chamber Maid Bow Tie Cleaning Swabs (BTCMS-50) are specialised maintenance consumables engineered to clean the locking lug recesses inside dual-lug bolt-action rifle receivers. Standard patches pushed down the bore bypass the internal recess geometry where carbon, copper fouling, grit, and excess lubricant build up. Made from 100% heavy-duty industrial wool felt, these swabs feature a patented two-lobe bow-tie profile (US Patent #D562,935) that mirrors internal lug channels to prevent bolt binding, headspace inconsistencies, and lug galling.

Key Features:

• Dual-Lug Chamber Geometry: Features a patented bow-tie cut specifically shaped to fit the opposing locking lug recesses of traditional two-lug bolt actions.
• Industrial Wool Felt Construction: Dense wool felt absorbs bore solvents, carbon removers, and lubricants, stripping debris from receiver recesses without shredding.
• Simple Mounting Interface: Mounts directly over a standard .30 Caliber bore brush (nylon bristle recommended) attached to a chamber or cleaning rod.
• Non-Powered Mechanical Operation: Requires no external power or specialised tools beyond standard cleaning rods and brushes.

Who is the Proshot Chamber Maid Bow Tie Cleaning Swabs 50 Pack For Two-Lug Bolt Guns for?

• Precision benchrest shooters — Requires maintaining strict headspace consistency and smooth bolt operation on dual-lug bolt-action rifles using a dedicated 50-pack supply of wool felt bolt action lug cleaning swabs mounted to a .30 Caliber bore brush.
• Hunters and pest controllers — Requires stripping abrasive field dirt, carbon, and solvent residue from Tikka T3x or Remington 700 dual-lug actions using swabs designed for two-lug bolt guns with a .30 Caliber bore brush mounting interface.

Less suitable for: Bolt-action or semi-automatic systems with three-lug, six-lug, or multi-lug configurations (such as AR-15 platforms or Weatherby-style actions); these systems require dedicated star-chamber cleaning pads or multi-lug rotating brushes matched to their specific lug geometry.
