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 the strongest firearms-grade aluminum alloy. This alloy is not only strong, it's light-weight. Each individual Thread Protector is machined using the latest CNC machines and techniques.


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 an accessory on or leave the threads bare. These protectors are designed to be screwed on when an accessory is not being used, to protect the threads.
