Several people have expressed an interest in building their first AR and we have discussed where to buy the parts on several occasions.
The guys in the following video have done some testing of the durability of many of the uppers now on the market by testing them to destruction.
What is the purpose of testing in this manner? simply showing the consumer what the product will endure before it fails, and can the average person make it fail.
They do not beat it with a sledge hammer, smash concrete blocks with it or put it in a vise and twist it until it bends. They shoot it. They just shoot it in a manner most of us could never accomplish.
This test is the destruction of a PSA entry level 16 1/2" barreled, gas tube carbine barrel. It is completely stock and just as we would buy one from the online store. The upper alone costs about $200 everyday price from PSA. This is also one of the barrels offered in their full build kit at $350-$375.
These guys use a full auto lower and get more rounds through the barrel in a shorter time than any normal person would ever be able to accomplish.
They put magazines through the rifle at full auto as fast as they can drop and reload mags and the final burnout occurs after running two 50 round drums through the rifle and catching the handguards on fire.
Most average Joe AR purchasers or builders do not own as may magazines as these guys use, the equal to 15/30 round mags, so most of us could never come close to repeating this action.

I think I can safely say that I might wear out one of these uppers over the course of time, but it is going to be a long time.
