Carbine-length barrels - 14.5" to 20" - are the most common in modern sporting rifles, and this 30" flexible gun cleaning cable covers them all with room to spare. Drop the cable through the chamber, thread a brush or jag onto the end at the muzzle, and pull it back through. Breech-to-muzzle cleaning in the correct direction, every pass, without a bore guide or rigid rod.
The AR-15 platform dominates this barrel length range, and it was designed to be cleaned from the breech. A flexible cable makes that practical without a full bench setup - feed it through the ejection port or the buffer tube channel, attach your cleaning accessory, and pull. No rigid rod flexing against the bore walls, no muzzle crown contact, no risk of rod-to-rifling wear. For range-day maintenance between detailed home cleanings, this is the tool that fits in your range bag next to your magazines.
Works with every 8-32 threaded gun cleaning accessory: bore brushes, brass jags, cotton mops, and slotted tips. Coated stainless steel cable resists solvents and coils flat for storage. One bore cleaning cable that pairs with the brushes and jags you already own.
