Greetings everyone, I recentlly purchased a Bushmaster AR-15. I have really been enjoying it at the firing range and have learned quite a bit about the operation of it. I have some basic questions that I have searched the forum for an answer and have been unable to find. The first one is, where can I find a list of good upgrades on parts for different companies and which brands are the best? Also, could anyone explain to me the matience schedule of gun broken down by after everytime you shoot, once a week, every 6 months and so on. Thanks in advance!!

Welcome to the site!

if your gun is running fine, dont worry about "upgrades"

h/w, some basic ones are: Accuwedge, gapper, and O-ring for the extractor; wolf springs and H-buffer

personally, i would just save the money and get USGI mags and ammo
