Availability: In Stock
A rifle thread protector is one of those small but essential pieces of gear that saves you from a expensive problem down the road. The Yankee Hill Machine YHM-3411-B is a 5.56mm thread protector sized for 1/2-28 muzzle threads with a .730" outside diameter—the standard setup for most modern AR-platform rifles and common 5.56 barrels. It threads on in seconds and sits there doing its job: keeping dirt, debris, and accidental dings away from your barrel's crown and threads while your rifle is slung, stored, or transported.
Yankee Hill Machine has built a solid reputation for no-nonsense muzzle devices, and this protector reflects that straightforward approach. The knurled exterior gives you positive grip during installation and removal, so you're not fumbling around with tools or stripping the threads. It's the kind of thing that seems minor until you're the one who banged a bare muzzle thread against a truck bed or fence post—then it becomes very important, very fast.
Whether you're a hunter who likes to keep optics and barrels in top condition, a range shooter managing multiple uppers, or someone who simply wants to preserve their investment between outings, this protector is affordable insurance. Black finish matches most modern rifle setups. Install it and forget it—until you actually need to swap it for a muzzle device, at which point you'll appreciate how easy it threads on and off.

Yes, if your barrel is threaded 1/2-28 with a .730" muzzle diameter. This is the standard thread pitch and size for most 5.56mm/.223 AR-pattern barrels. Check your barrel specs to confirm the thread pitch and OD before purchasing.
Simply thread it on by hand using the knurled grip. No tools required. To remove, unthread it by hand in the opposite direction. The knurled surface gives you plenty of traction to make installation and removal quick and secure.
It covers the muzzle threads and protects the barrel crown from dirt, dust, and accidental impacts while your rifle is stored or transported. It's a temporary protective cap, not a permanent muzzle device like a flash hider or compensator.
No. This is a protective cap designed for storage and transport only. Remove it before firing to prevent obstruction or damage to the protector itself.
