The Kaw Valley Precision Thread Adapter, 1/2×28 to 5/8×24 (Kaw Valley Precision part no. KVPADPT1303) lets shooters mount 5/8×24-threaded muzzle devices or suppressor mounts onto a barrel cut with the smaller 1/2×28 thread pitch common on many 5.56/.223 and 9mm barrels. This adapter is useful for shooters who own a suppressor or muzzle device threaded for larger-bore cartridges like .30 caliber and want to run it on a 1/2×28-threaded host barrel. Kaw Valley Precision machines its thread adapters to hold tight tolerances so the mounted device sits square and concentric to the bore. It’s a practical, affordable way to expand muzzle device compatibility across a mixed collection of barrels.

Frequently Asked Questions

Can I use this to run a .30-caliber suppressor on a 1/2×28 barrel? If the suppressor mount is threaded 5/8×24, this adapter lets you thread it onto a 1/2×28 barrel, though always confirm the suppressor is bore-diameter rated for your barrel’s caliber.

Does this adapter affect accuracy? Properly installed thread adapters are machined for a concentric, square fit and generally have minimal impact on accuracy.
