A Deep Dive into the Kleen-Bore GL40/LL1305 System Components

The strength of the Kleen-Bore GL40/LL1305 Less Lethal Weapons Care System lies in its thoughtful selection of high-grade components, each chosen for its specific role in providing a thorough and effective clean. Let’s explore what makes each element vital for comprehensive weapon maintenance:

The Foundation: Robust Cleaning Rods for Wide Bores

At the heart of any effective cleaning kit is a reliable cleaning rod. The Kleen-Bore system includes a 3-piece large diameter aluminum cleaning rod. Unlike standard rifle or pistol rods, this rod is specifically engineered for the wider bores of 37mm, 40mm, and 12-gauge firearms. Its aluminum construction provides a rigid, yet non-marring, platform for pushing brushes and mops through the barrel, preventing damage to precision rifling or smooth bore surfaces. The multi-piece design allows for compact storage while providing ample length when assembled, ensuring that even the longest barrels can be effectively cleaned from breach to muzzle. This robust foundation is crucial for safely and efficiently navigating the barrel, ensuring that cleaning tools reach every part of the bore for maximum effectiveness.

Precision Brushing: Tackling Stubborn Fouling

Effective cleaning hinges on the ability to dislodge carbon, lead, and plastic fowling. The Kleen-Bore kit provides two distinct, heavy-duty bore brushes:

• 37/40mm Heavy-Duty Phosphor Bronze Bore Brush: This brush is purpose-built for the large calibers of grenade launchers and gas guns. Phosphor bronze bristles are stiff enough to aggressively scrub away even the most stubborn residues without scratching or damaging the steel bore. Their robust construction ensures longevity, allowing for repeated use without degradation in cleaning power. This specific brush size is paramount for achieving a comprehensive clean within these wider bore dimensions.
• 12GA Phosphor Bronze Bore Brush: Similarly, this brush is tailored for the 12-gauge shotgun bore, employing the same durable phosphor bronze bristles. Shotguns, especially those firing a variety of less-lethal or specialty rounds, can accumulate significant plastic wad residue and carbon. This brush is adept at scouring these deposits from the bore, restoring the barrel’s interior to its original, smooth condition. The correct size and material of this brush are essential for the unique challenges of shotgun barrel maintenance.

Thorough Absorption and Lubrication: High-Quality Cotton Mops

After mechanical brushing, the next critical step involves applying solvents and then thoroughly wiping the bore clean and dry. The kit includes:

• 37/40mm Heavy-Duty Cotton Bore Mop: This large-diameter cotton mop is designed to perfectly fit the bores of 37mm and 40mm launchers. It excels at applying an even coat of solvent or lubricant throughout the barrel, allowing the chemical action to penetrate and loosen fouling. Subsequently, it's highly effective at absorbing and removing loosened residue and excess solvent, leaving the bore clean and ready for protection.
• 12GA Cotton Bore Mop: Just like its larger counterpart, this cotton mop is specifically sized for 12-gauge shotgun barrels. It ensures optimal distribution of cleaning solutions and efficient removal of fouling, preparing the bore for final protection. The softness of the cotton prevents any scratching while ensuring maximum contact with the bore surface for superior cleaning and drying.

Specialized Application: The 12GA Shotgun Jag

For 12-gauge shotguns, a specialized tool is often preferred for patch cleaning:

• 12GA Shotgun Jag: This pointed tool allows for precise placement and secure retention of cleaning patches, ensuring maximum contact with the bore’s surface as the patch is pushed through. The jag helps drive the patch into the rifling (or smooth bore), providing a thorough wiping action for final cleaning, drying, or application of a protective oil layer. Its design minimizes the chance of patches bunching up or leaving residue behind.

Versatility for Detailed Cleaning: The Double-End Nylon Utility Brush

Beyond the bore, other parts of the weapon require meticulous attention:

• Double End Nylon Utility Gun Brush: This versatile brush is a workhorse for cleaning various nooks, crannies, and external surfaces. Its dual-end design provides both a large brush head for broader areas and a smaller, more precise head for tight spaces, bolt faces, trigger groups, and other intricate mechanisms. The nylon bristles are stiff enough to dislodge dirt, carbon, and grime from metal and polymer surfaces without causing scratches or abrasions, making it ideal for the exterior of launchers and shotguns.

Advanced Cleaning and Protection: Pro-Shot Chemicals

The Kleen-Bore system thoughtfully integrates premium chemical solutions from Pro-Shot, a respected name in firearm care:
