Now that's just dirty...
I am a big fan of West System epoxies for cycling and marine use, but the heat deformation temperature (NOT failure point) is only about 120 degrees while the ultimate glass transition temperature is only 120-140 degrees (F)! I know most of us don't really plan on rapid firing our rifles as much as envisioned originally but a handguard must get hotter than that...
So maybe I'll concur that wood glue is for wood.
