curtton said:no , this was a brits trial, stated in r.blake stevens THE FAL RIFLE book, page 149.
it state "trials reveals that the nylon handguard is less efficient for heat insulation than the wooden pattern".
thanks for that, My info came from the list of changes which doesnt record trials data. Funny that it didnt seem to stop the introduction did it? Maybe it wasnt enough of an issue as we rarely went to a proper war and the ammo scales were only 80 rds per rifleman. That said it probably was cost and heat was less of an issue as we didnt have full auto versions and there would be more risk of a cook off than burning your hands. We were taught to open the working parts after sustained rapid to allow cooling but nothing regarding our personal comfort or safety regarding heat and I joined in 81 when the marylon was standard even on the GPMG.
