The 1x spitfire dot size is 3 moa, which is large by most standard. Not sure what you're looking for in a reticle because there are no other 1x glass etched reticle out there besides the old Leupold Prismatic with a cross hair and 3 moa dot (Leupold no longer makes this). Don't even bother with the Burris AR1X, its reticle is way too clutter with the center dot being 4.4 moa and substension lines, looked good on paper but when view at 1x, all the lines tend to clump together. Most shooter already gotten rid of this faux pas after the first few months on the market (Burris promised a new reticle based on gunners' input but it has been 2 years!)
Sling wise, stick with the well known brand like Blue Force Gear, VTac, or Magpul. For the Scorpion EVO, the two factory sling points are ring type and you need hk-style hook sling ends. Most useful is 2-point slings with quick length adjustment like 3 named before.
