In the market for my first AR-15 and have been browsing uppers online and I was originally set on a 20 inch RRA A4 standard flat top, but I just saw PSA has a great deal on their 16 inch mid length upper and it looks hard to pass up. The RRA is about $200 more than the PSA and both come with bcg/ch. My purpose is to put together a varmint/plinking gun. The hunting it would see is coyote hunting that rarely stretches beyond 300 yards. Either one will be getting a fixed stock because I hate the way collapsables feel. Ill put on a 3-9 scope if I get the 20 inch or a 1-4 scope for the 16 inch. I have a feeling the RRA will be more accurate, but is it worth the extra $200?
