Heckler & Koch
If you run an HK Mark 23 .45 ACP, keeping those muzzle threads protected is part of responsible gun ownership. The HK Thread Protector Mark 23 is a straightforward steel accessory designed to shield your pistol's barrel threads from damage when you're not running a suppressor or other muzzle device. It's a small detail that pays dividends over time—protecting both the thread geometry and the crown from wear, corrosion, and accidental dings that can compromise your optics or sound suppressor fit down the road.
This is steel construction with a steel blue finish, built to the precise 16x1mm right-hand thread spec that HK Mark 23 owners depend on. It screws on tight and stays put, so you get consistent protection whether the gun is in the safe or slung for a training session. Nothing fancy, nothing complicated—just reliable thread protection from the manufacturer who knows these pistols inside and out.
Whether you're between suppressors, need a backup protective cap, or simply want to preserve your threads for resale or warranty purposes, this is the no-nonsense choice. It's the kind of small-dollar accessory that keeps your investment running clean and ready.
