Does anoyone have a link to this training class, or info on it like cost, and schedule? I couldn't find anything in the article, except that it was in Camden Tennessee. recievers do not get as hot as the barrel in most guns, since most guns do not send the hot gasses into the reciever (that’s why no-one makes a plastic AR direct-impingment upper). forends will melt, but recievers don’t get near as hot.

Plastic are very poor choice of material to use when it comes to handling heat. Yet companies like FN keep insisting on using cheap plastic for their receivers instead of going to Aluminum or Steel. My cousin and I always get a laugh when gun companies overcharged for their plastic firearms. Molding plastic is cheaper then milling aluminum or steel. So I never understood why the cost saving isn't pass to the consumers. Anyway, the AR that was used probably wasn't capable of full auto or burst and it wasn't a hot day/week by the looks of it.

Another proof that plastic will melt while shooting. God forbid if this happen in a arid environment like Iraq or Afghanistan with plastic receivers in a firefight. The rifle can function if the plastic handguard melted but not with a deformed plastic receiver. Yeager sure run them hard in his class doesn’t he?
