Rocksett is essentially the "gold standard" in the firearms industry for securing muzzle devices (flash hiders, brakes, and suppressors). It’s unique because, unlike standard thread lockers, it thrives in high-heat environments where others fail.
Key Technical Specifications
Rocksett 15017 is an inorganic adhesive that works more like a ceramic cement than a plastic glue.
- Temperature Resistance: Withstands temperatures from -180°C up to 1,100°C.
- Shear Strength: Approximately 450–500 psi at room temperature.
- Cure Time: 24 hours at room temperature (faster if heat-cured).
- Chemical Properties: Resistant to acids, alkalis, oils, and fuels.
Why Use Rocksett Over Red Loctite?
The most common mistake is using Red Loctite ( or ) on a muzzle device. Here is why Rocksett is the better choice for this specific application:
Application Best Practices
- Degrease: This is the most critical step. Clean both the barrel threads and the muzzle device threads with acetone or 99% isopropyl alcohol.
- Less is More: Apply only one or two drops to the threads. If you over-apply, it can be extremely difficult to remove later.Torque: Hand-tighten and then torque to your manufacturer's specs (usually 20–30 ft-lbs).
- Cure: Let it sit for a full 24 hours before heading to the range.
How to Remove It
Because Rocksett is a ceramic-based adhesive, it is water-soluble. If you need to swap your muzzle device:
- Submerge the muzzle in a cup of warm-to-boiling water for 12 to 24 hours.The water breaks down the bond, allowing you to unscrew the device with standard tools.
- Note: Heat (torching) does not work well for removing Rocksett because it is designed to withstand heat. Use water!
Pro-Tip: If you are running a suppressor, the heat generated by a few rapid-fire magazines can easily exceed the failure point of Loctite, causing your muzzle device to unscrew inside your expensive silencer. Use Rocksett.
