Patterned Thread Protectors

Availability: Ships within 2 business days

Product Details

These awesome thread protectors offer a custom look. Screw them on to protect the threads when an accessory is not being used. 

They're constructed from 7075 aluminum. This is the same high quality aluminum used for the upper and lower receivers of high-end billet AR's (less expensive AR's use 6061 aluminum). Each individual thread protector is machined using the latest CNC machines and techniques.

Made in the USA!


  • All pistol thread protectors:  0.4" Long & 0.6" Outside Diameter
  • All rifle thread protectors: 0.7" Long & 0.75" Outside Diameter

Thread Pitch:

All designs & all colors are currently available in the most common size, 1/2 x 28 for 9mm/22lr barrels (generally aftermarket barrels).

The following thread pitches are also available, in limited designs and limited color options: 

  • M13.5 x 1 LH (9mm & 22lr Euro/Metric - for Glock/Sig/HK with factory threaded barrel)
  • .578 x 28 (45ACP US)
  • M16 x 1 LH (45ACP Euro/Metric - for Glock/Sig/HK with factory threaded barrels) 
  • 1/2 x 28 (.223 & 5.56 rifles - AR15's and some AR9's - ** Please see important note below about AR9's) 
  • 5/8 x 24 (For .30 Cal Rifles - 308 AR10 - 300BLK AR - 300 WIN MAG, etc.)


Aftermarket Barrels: Most threaded pistol barrels are aftermarket. These are made in the US and use the US threading (1/2 x 28 for 9mm or .578 x 28 for .45).

Factory threaded barrels: New factory Glocks (also Sig & HK) that come stock with threaded barrels are made in Europe and use the Metric threading (13.5 x 1LH for 9mm and M16 x 1LH for .45).

9mm AR's: Most 9mm AR's are threaded 1/2x36. We do not offer protectors in this thread pitch at all. However, a small percentage of 9mm AR's are threaded 1/2x28. If, in fact, you have a 9mm AR that is threaded 1/2x28, the pistol 1/2x28 thread protectors will NOT work! They will be too short and the diameter will not match the diameter of the AR barrel. So do not order the option marked as "US 9mm & 22 LR - 1/2 x 28". Please order a Rifle Thread Protector, listed as ".223/5.56 Rifles - 1/2 x 28", which will be longer and have the same diameter as the AR barrel! 

Don't shoot with these screwed on: When you are shooting, screw on an accessory or leave the threads bare. These protectors are designed to be screwed on when an accessory is not being used, to protect the threads. It is NOT recommended that you shoot the pistol with the thread protector installed. If you do, you should tighten it after each mag fired just like any other muzzle device that is not permanently attached or clamped down with set-screws.

Included O-Ring:  Every order will ship with a loose, optional O-Ring. These thread protectors have finer threads, because if they are too thick/coarse, they won't fit on all barrels. This is pretty standard, as most accessories have finer threads and most barrels have coarser threads. But if your barrel has fine threads, or if you feel you want a tighter fit for the thread protector, just use the O-Ring. 

AVAILABLE DESIGNS - Hover/touch to view design name. Click/tap to enlarge.

Note: USA Flag and Muddy Girl are the only two designs that have a synthetic colored band wrapped around the aluminum protector. These are designed to be primarily "for show" as the designs will wear over time. All other designs are 100% 7075 aluminum.

Its great

The only thread protector I could find that stayed on while firing and didn't come loose

Beautiful finishing touch...

I purchased the black honeycomb thread protector to finish the look on my Zev OZ9 compact... I wanted a threaded barrel for my suppressor, but wanted the thread protector to match the aesthetic of the backplate and mag release. Fortunately, this thread protector looks great!

Had an issue, but was resolved

So I feel in love with the American flag pattern thread protector. I quickly ordered one for my Glock 19 P80 build, then say by the door like a kid on Christmas for the mail man to bring it. When it arrived I quickly tore open the package, and there it was in all of its Merica beauty. Went to throw it on the gun but alas there was an issue, the thread protector was missing one vital detail, it wasn't threaded. I went to the computer to ensure my order was correct, and it was. So I emailed the gun goddess and waited for a reply. To my surprise I received a call soon after sending the email, which I expected to hear from them a day or so later, so this was nice to see they care. The woman I spoke to asked me to send a couple pics to her of the non threaded thread protector. She then assured me that they would take care of this the next day as it was outside business hours, which is why I didn't expect the call. So the next day I get an email saying that they spoke to the manufacturer about the issue and they were getting a replacement sent out. So I waited for the new one, which came pretty quick. Opened the new package to find a note that the owner of the manufacturer sent me. Not only did he make things right with my initial order, he threw in an additional thread protector for the inconveniences it was a small gesture but was nice to see they take their customer service, and customers needs and place it high on their list. I love both (well 3 if you count the first one) of my thread protectors and will definitely order from the gun goddess again. The friendliness and customer service alone has gotten them a customer for life, and I will refer anyone I know to them 1000%. Thank you again for the help and quality products.
