Just picked up my first AR15 today. I've been mostly an AK guy but had a strong itch to purchase an AR lately. I bought a DPMS Panther 0.223 A2 Tactical 16" from Crossroads Firearms (great, great, great place to purchase but that's a different story). The build looks very sturdy and I got a quick, detailed tutorial on how to take apart and clean the rifle (Joe physically took it apart for me and pointed out every nook and cranny of the AR). Anyways, I don't even know where to get started. Knowing myself, i'm a binge buyer when it comes to accessories but I must hold back on temptations because I am just lucky I was able to make the AR purchase. I've heard that AR15's require a lot of maintenance and what not but I am prepared for the tasks and tedious processes to come. I am very excited to finally add an AR to my collection and hopefully when the weather gets better i'll have time to actually "play". Anyone else have the DPMS Panther A2 Tactical? Any reviews? Also, what are the benefits of having a quad rail? Please excuse my laziness but I would indeed prefer the friendly interaction =).
