GrovTec Suppressor Alignment Rod – .223 / 5.56mm
The GrovTec Suppressor Alignment Rod (GTHM372) is the most critical safety tool for any shooter running a suppressed 5.56 NATO or .223 Rem platform. Baffle strikes are a common and costly nightmare for NFA owners, often caused by non-concentric barrel threading or improper muzzle device installation. This precision-ground rod acts as a definitive physical gauge, ensuring that your silencer’s internal aperture is perfectly centered with your rifle’s bore before you fire the first round.
Machined from ground O1 tool steel and finished with a corrosion-resistant black oxide coating, the GTHM372 is engineered to an exacting straightness tolerance. At 15 inches in length, it provides ample engagement with the rifling while clearing the end cap of even the longest "full-size" suppressors. Simply insert the rod through the suppressor and into the bore of an unloaded firearm; a perfectly centered rod indicates a safe-to-fire condition, while any deviation allows you to correct alignment issues before they result in permanent damage to your suppressor or a dangerous malfunction.
Safety Note: Always verify alignment when moving a suppressor between different hosts (e.g., from an AR-15 to a Tavor) to ensure the thread shoulders on each barrel provide a consistent, concentric lockup.
Key Features
- High-Precision Alignment: Ground to strict tolerances to ensure a perfectly straight reference for bore-to-silencer concentricity.
