Description
The LANTAC USA Timing Shims are a precision 1/2×28 shim set engineered for accurate muzzle device alignment and timing on AR-15 pattern rifles chambered in .223 Remington and 5.56 NATO. Designed to correct muzzle device timing and indexing, these shims slide between the barrel shoulder and the device to dial in proper alignment with the gas port and keep the installation concentric without play.
Manufactured from stainless steel for corrosion resistance and long service life, the shims are sized to the common 1/2″-28 thread pitch used on most .223/5.56 AR-15 barrels. The kit is Made in USA and is intended as a utility accessory for gunsmiths, armorers, and end users installing or shimming compatible muzzle brakes, compensators, and flash hiders.
