Grovtec AR 1/2-28 Thread Protector – Precision Fit for AR Rifles

Your AR rifle's muzzle threads are precision-engineered and expensive to replace. Whether you're rotating between suppressors, flash hiders, or running iron sights, a Grovtec AR 1/2-28 thread protector keeps those delicate threads safe from dings, dirt, and damage when no device is installed. This is one of those small-cost insurance policies that pays for itself the first time you avoid a re-threaded barrel. Slip one on and forget about it—or swap it out in seconds when you're ready to mount your next muzzle device.

Built from steel with a black oxide finish, the Grovtec protector is American-made and built to last. The knurled exterior gives you a sure grip when installing or removing it, so you're not fumbling with tools or wrestling with a smooth surface. It threads onto your AR's 1/2-28 muzzle and sits flush, giving your rifle a clean, finished appearance whether you're on the range, in the field, or the gun's in the safe.

If you're serious about protecting your investment and keeping your AR's muzzle in factory condition, this protector is cheap insurance. Throw one in your range bag and keep your threads protected between suppressors or other muzzle devices.

Frequently Asked Questions

Will this thread protector fit my AR-15?

Yes, if your AR has a 1/2-28 muzzle thread. Most AR-15 barrels ship with 1/2-28 threading, but verify your barrel's thread pitch before ordering. If you're unsure, check your barrel marking or the manufacturer's specs.

Can I leave the protector on if I want to install a suppressor or other muzzle device?

No. Remove the thread protector before mounting any muzzle device. The protector is designed for when your rifle has no device attached.

How do I remove the thread protector?

The knurled exterior provides grip for hand-removal. Simply hold the barrel steady and unscrew the protector by hand—no tools needed. If it's tight, a light tap with a rubber mallet or wrapped in a rag for better grip will loosen it.

Is this protector made in the USA?

Yes. This Grovtec thread protector is American-made.
