GrovTec Thread Adapter 1/2x28 to 5/8x24 – Universal Muzzle Device Converter

The GrovTec Thread Adapter converts a 1/2x28 threaded barrel to accept 5/8x24 muzzle devices, allowing shooters to run larger-bore muzzle brakes, compensators, or flash hiders on barrels originally threaded for smaller calibers. This adapter is commonly used to install .30 caliber muzzle devices on .223/5.56 barrels or to accommodate legacy suppressors with 5/8x24 mounts.

Constructed from steel with a durable finish, the adapter installs by threading onto the existing 1/2x28 barrel threads and provides a precision 5/8x24 external thread for your chosen muzzle device. Check that your barrel has sufficient thread engagement and overall length to safely accommodate both the adapter and your muzzle device. Always verify timing and concentricity after installation to ensure safe operation.
