Quick Answer
The maximum length for a suppressor on a hunting rifle varies by state and manufacturer, but generally ranges from 8.5 to 9.25 inches in length, measured from the barrel's muzzle end.
Choosing the Right Suppressor Length
When selecting a suppressor for hunting, consider the rifle’s barrel length and intended use. A shorter suppressor is often preferred for compact rifles and varmint hunting, while a longer suppressor may be more effective for large game hunting and quieter operation. Look for suppressors labeled as “hunting” or “long-range” for better performance.
Barrel Threading and Mounting
Before attaching a suppressor, ensure the rifle’s barrel is threaded in 1.875" x 24 TPI (threads per inch) or 5/8"-24, which is the standard for most suppressors. Use a torque wrench to secure the suppressor to the barrel, applying 30-40 ft-lbs of torque. This helps prevent damage to the threads and suppressor mounting.
State-Specific Laws and Regulations
Suppressor laws vary by state, so research local regulations before purchasing and using a suppressor for hunting. For example, California, Delaware, Hawaii, and New York have specific laws governing suppressor use, while states like Alaska, Arizona, and Utah have relatively lenient regulations. Always check the National Firearms Act (NFA) and state-specific laws before using a suppressor for hunting.
