Ok, so I purchased a DPMS Oracle for a gift for someone and it doesn't come with sights. I'd like to make sure I have a follow up gift of some sights or a quadrail the sights can be mounted to. Here's my dilemma: 1. The high profile gas block has a rail on it but it's still lower than the rail on the upper. Are there good sights I can purchase that will work with this setup? 2. I have Magpul flip up sights on my AR which I'd also just as soon put on this one. Is there a quadrail system any of you know of that would work by fitting around/incorporating the high profile gas block? Or am I stuck with a 7" quadrail until I can switch the gas block to a low profile? Thanks for your time.
