Hello everyone. I have recently had the privilege of putting together my fist AR-15. I already have enough carbines in my collection, so I opted for a 24" RRA Varminter upper and a RRA lower with a 2 stage NM trigger that I got a screaming deal on (free). The rifle is entirely complete, however I am having some trouble with mounting the optics. I have read so much contradicting information on the web that my head is spinning! In particular, I am unsure about what type of rings I should purchase. I've read everything from people saying that medium rings will get the job done (which I have a hard time believing), to people suggesting extra high rings (which apparently still aren't tall enough). Also, there are those who claim that if you aren't using one piece setups, you are compromising accuracy. Is this true? So if you have any advice, or can tell me what type of setup you are using, I would be very grateful. All I want to do is get this beauty fitted so I can take it out to the range.
