Kaw Valley Precision Plan B Muzzle Brake, M13.5×1 Left-Hand Thread

The Kaw Valley Precision Plan B (Kaw Valley Precision part no. KVPPLANBBRAKE11) is a muzzle brake cut with M13.5×1 left-hand threads, a less common reversed thread pattern found on certain pistol-caliber platforms where left-hand threading helps keep the device from backing off under recoil. Vented ports redirect propellant gas to counter muzzle rise and felt recoil, helping keep the sights on target for faster follow-up shots. Because M13.5×1 is not a universal thread size, confirming your barrel’s exact thread pattern before ordering is worth the extra step.
