The Kaw Valley Precision 3-Lug to 1/2×28 Barrel Thread Adapter (brand part no. KVP3LUG1228) converts a 3-lug quick-attach muzzle to standard 1/2×28 threading, letting shooters mount conventional threaded flash hiders, compensators, or suppressor mounts on a host built around the 3-lug pattern common to submachine gun-style pistols and carbines. Kaw Valley Precision machines this adapter to lock securely onto the 3-lug mount while presenting standard threads on the front, opening up the much wider selection of 1/2×28 muzzle devices to 3-lug-equipped firearms. It’s a practical accessory for anyone who prefers standard threading over factory 3-lug-only mounting options.

• Sold as a standalone thread adapter, separate from any muzzle device.
• Requires no permanent modification to the host’s 3-lug mount.

Frequently Asked Questions

Does this replace the factory 3-lug mount? No, it attaches to the existing 3-lug interface and adapts it to standard 1/2×28 threading rather than replacing the mount itself.

What can I attach to the 1/2×28 threads? Any standard 1/2×28-threaded flash hider, compensator, or suppressor mount compatible with the caliber of your host firearm.
