I took my not so top tiered, non-hard use, bottom feeder, hobby rifle DPMS/Del-Ton/Anderson/Bushmaster out this morning. What a disatster that was. My non TDP selector spring disintegrated into a rust colored powder 2 rounds into my second mag dump. Luckily i had a spare but after a swapped it out the non TDP pivot pin cracked in half and fell out. Without a spare i called it a morning and headed back to the house. Probably not a bad idea because the weather was warming up and I was worried my UTG handguard might melt if it got too much sun light.
