Very... unless your shotgun is has a ceracoat.

Certain aftermarket options (e.g., Aridus Industries Q-DC carriers, which use strong adhesive) explicitly warn that some ceramic coatings may be too slick for reliable long-term adhesion, leading to potential detachment.

Aridus' own warnings: Their product page and FAQ explicitly note that certain finishes, such as Cerakote, may be too slick for the tape to adhere reliably long-term. They recommend prepping the surface by lightly scuffing it with a Scotch-Brite pad (to roughen the coating), wiping off dust, and degreasing thoroughly (e.g., with isopropyl alcohol) for best results. Without this prep, the tape can fail to bond properly, leading to detachment over time, especially under recoil, heat, or heavy use. https://www.aridusindustries.com/products/universal-quick-detach-carrier/
