FrenchGunGuy highlights how design elements, such as handguard or sling mount configurations, can interfere with tri-lug suppressors. The video demonstrates that while not a fault of HK's design, these factors can be frustrating for users seeking to modify their firearms, often necessitating the use of direct thread suppressors as a workaround.
This video from Brownells Firearm Support Tech Caleb Savant provides a quick and practical tip on how to determine the thread pitch of firearm components, such as muzzle threads. He outlines the process using common tools like calipers for diameter measurement and a thread pitch gauge to identify the correct pitch.
