The problem with most home builds is that the builder uses sub quality parts. The second problem with home builds is that everyone builds them to THEIR choosing, which isnt a bad thing but when it comes time to sell it people think that because they paid 20 dollars for a grip that their rifle is now worth 20 dollars more. Or they spent 60 dollars on a low profile gas block instead of 20 for an A2 sight base so that means its worth what they paid for the gas block more.
