Yankee Hill Machine
The Yankee Hill Machine thread protector is a no-frills steel accessory designed to shield your rifle barrel's threads when you're running the gun naked—no muzzle brake, suppressor, or flash hider in place. Built for .45 caliber rifles with M16 x 1LH threads and a .750 OD bore, this protector keeps dust, debris, and dings off those threads so they stay clean and true for when you're ready to mount your next muzzle device. It's a small investment that prevents the kind of thread damage that can cost you a lot more to repair.
Whether you're rotating suppressors between rifles, testing different muzzle devices, or just keeping a barrel protected between range trips, a thread protector earns its place in your gun bag. This one is built from steel for durability and finished in black to match most modern rifle setups. It's the kind of simple, practical gear that experienced shooters and hunters keep on hand.
If you own a rifle with this specific thread pattern—M16 x 1LH, .45 caliber—and you want to keep those threads in field-ready condition without a permanent muzzle device installed, this protector does exactly what it's supposed to do, no marketing hype required.
| Thread Pattern | M16 x 1LH |
| Caliber | .45 |
| Outer Diameter | .750 OD |
| Material | Steel |
| Finish | Black |
Yes, if your barrel has M16 x 1LH threads and a .750 OD bore. Check your rifle's specs or muzzle device compatibility to confirm the thread pattern matches before ordering.
A thread protector simply caps off and shields your threads when no muzzle device is installed. It does not add any noise reduction, recoil control, or flash suppression—it's purely protective.
No. Thread protectors are designed as storage and transport protection only. Remove it before firing your rifle.
LH stands for left-hand threading, which rotates counterclockwise to install or remove. This is common on many rifle barrel specifications. Confirm your barrel threading direction before purchase.
