I have a two PSA ar9 lowers. One bone stock with about 1k rounds through it, another that is all PSA minus trigger, rail, buffer, and comp. I run hiperfire triggers. Anyways, 80k rounds later I'm a uspsa top 20 GM, and enjoy beating guys with multi thousand dollar rifles with my cheapo PSA. I think they are very well made, my barrel still looks fine, and I just plain dont have gun malfunctions. My personal experience has been fantastic, and when this gun finally wears out, I'll have another because they are great guns.
