Rocksett – 3ml

Flexbar Rocksett ceramic adhesive/cement (clear) – Rocksett is a ceramic adhesive that features an extremely high temperature rating of 2,105F. It is used primarily for suppressor mounts since it will not deteriorate from use with a suppressor since the ceramic is water based. It is also often used with gas block set screws although we typically prefer one of the red Loctites (271 or 272) for this. For removal the most common method is soaking the assembly in boiling water for 15 minutes to soften it. You can also strike a steel assembly with a brass hammer to shatter the adhesive but this should be done with caution.

On suppressor mounts, use an amount roughly the size of a pea on the male thread toward the end. The muzzle device will coat the rest of the thread as it is installed. Over use can increase cure times so be sure not to over do it. Normal cure time is 24 hours so do not shoot the gun during that window. You can also “heat cure” the muzzle device by holding it over a heat gun at low temperature (150-200F) for 15 minutes. This drives out the moisture and can cure the Rocksett faster.

Rocksett can go bad over time so discard it when the liquid starts to turn yellow instead of clear or thickens up (sort of like honey). The tip of the syringe may dry out with repeated use as well so use a needle or small pick to clear the tip and purge a small amount onto a rag.
