I own a psa, i use it and beat the crap out of it with cheap ammo. I have higher end ar's also. But for the price. I can take camping on a mountain in maine for a week. and get it soaked from rain and snow. Drop it in a stream. Much rather do that with a 400 dollar ar-15 then a 1500 dollar colt. So far, that PSA has been 100 percent reliable.
