So I just purchased my very first AR-15 Today. I got a Colt LE6940 and am stoked for it to arrive. I've been looking around and there is an overwhelming amount of different accessories to add to it...problem is I want them ALL, and don't know which ones are good. In my experiences while shopping for which AR i wanted in the first place, i've come to realize that these days "good" is really just a relative term that has different meanings to different people, so instead of asking for "why do you think this is best" or something to that effect, id rather instead ask "what do you use?" Don't even really need a "why" ... You're all obviously big gun enthusiasts as well, why else would you be here? What im most interested in is a bayonet, optics, flash light, bi-pod, and really anything else that would look badass that I haven't thought of yet. Any and all opinions 100% welcome. P.S. if you could post where you typically purchase your items from, that'd be most appreciated. I usually use BudsGunShop and Cheaperthandirt.com ... but both of them seem to be lacking in 'available options'
