000buckshot: i didnt mean to say that all olys are crap or that all colts are perfect, i was just saying that in general, more problems are encountered with less expensive brands. Theres plenty of people out there who are content with olys, dpms, del-ton, and what have you, but the difference between you and the person i was responding to is that you seem to understand that not all ARs are finicky or unreliable. Its just that in general, there seems to be less problems encountered with more expensive brands. As far as jbauch saying that ARs are finicky with ammo. this is just another generalization. Some brands may be, but when you buy an AR from a reputable company and use decent magazines, your AR will not care whether you use fmj, softpoint, hollowpoint, wolf, silverbear, federal, or winchester. I dont spend more than 10-15 minutes cleaning my AR after a range session. But I clean ALL my guns after I shoot them, no matter what kind they are, so that is not a problem. I will not disagree that ARs need to be lubed properly, or the WILL eventually puke. Some people say that ARs need to be kept white glove clean. that is total bs. they NEED to have lube more than anything. So to answer the OPs question, as much as I love my AR, it is hard to come close to being glock reliable. you can probobly go through 50,000 rounds on a glock and not need to clean it whereas with a good AR, you will need to lube it probobly every thousand rounds or so to keep it going well.
