What customers say about "Key Specs"
Vortex Sparc 2 (SPC-402) Red Dot MOA Scope
  • The S2's lens caps flip up nicely, but are just pressed on, and shift easily from side to side if bumped.
  • It's small, light, and uses little upper real estate. You can have flip up irons up at the same time no problem.
  • The base that comes with it is actually very nice considering it was free. I expected to have to upgrade, but no concerns now, the optic is held securely in place.
  • The optic is pretty tough, it's taken some banging around and works just fine.
  • The red dot will not appear solid if you have astigmatism. It has a slight "starburst" appearance to me, but this can be mitigated by using it in conjunction with back up iron sights, as I did. Not the sight's fault really, just something to keep in mind.
Vortex StrikeFire 2 (SF-RG-501) Cantilever Mount Red/Green Dot Scope with Vortex Optics Hat
  • The optic came in a box with all the necessary hardware for mounting (it came with a cantilever mount for lower 1/3 co-witness), a torx key for the mount screws, obligatory paperwork, an off-brand battery, and the hat.
  • Cantilever mount makes use of a magnifier possible
  • Shipping was lightning fast, packaging was superb, and mounting the scope to the rail was as simple as tightening a screw..
  • Clear glass, great reticle, wonderful adjustment, and sturdy housing for a premium package at working man's prices!!
  • At highest brightness settings, there is a bit of a hue on the perimeter of the reticle.

What customers say about "Features"
Vortex Sparc 2 (SPC-402) Red Dot MOA Scope
  • The LED is plenty bright, I have no trouble seeing it in sunlight whatsoever.
  • The glass is as clear as an Aimpoint. This means that the optic has a very slight blue hue just like the Aimpoint, but is not excessively dark. This is part of the red light filtration coatings they put on the glass.
  • The red dot is very easy to see and the various levels of brightness will fit any lighting situation you encounter.
  • The glass is crystal clear and won't fog. The quality of this optic far exceeds it's modest price tag.
  • It's lightweight and compact. Even on my 10.5" blackout there is still plenty of room for my MBUS.
  • The adjustments (brightness, windage, and elevation) to me, are on the "soft" side. In other words, it can be difficult to feel the "click" when making corrections, or powering on the unit. I'm comparing it to other optics I've owned, from Redfield to Zeiss.
Vortex StrikeFire 2 (SF-RG-501) Cantilever Mount Red/Green Dot Scope with Vortex Optics Hat
  • The lens covers are included and fit firmly to the unit. no slop or rattle.
  • Being able to change the color of the dot sights Buttons are very easy and accessible. The adjustments are plain and easy to use.
  • Good sight, solid mount and feel but in retrospect I don't like the red/green feature.
  • I like the auto shutoff feature (I tend to forget things like turning things off)
  • Great optic for the money, impressive features. It's nice to be able to change not only the brightness but the color of the reticle from red to green.

What customers say about "Power"
Vortex Sparc 2 (SPC-402) Red Dot MOA Scope
  • It uses the Cr 2032 battery. AAA's would be nice, but that would make it bulkier. Can't have it all, I guess.
  • Excellent battery life. I haven't measured how many hours but what I can say is that I leave it on at night since my rifle is always at the ready.
  • Nice flip caps are included and the battery life is excellent.
  • The optic shuts off by itself, saving battery life. It also comes with extra spacers and an extra battery.
  • The battery life is not that of an Aimpoint but still very good. Just be aware that you will not leave this thing on for 3 years and it still be good to go. Have a spare battery.
Vortex StrikeFire 2 (SF-RG-501) Cantilever Mount Red/Green Dot Scope with Vortex Optics Hat
  • Other red dot sights I have utilize a ruby coating on the reflecting lens which, while it slightly reduces the light transmission, also very effectively reflects the light from the diode extending battery life by reducing total light needed.
  • Great battery life. The batteries are also the same type as my preferred tac light from Streamlight.
  • I really like the unit. They are easy to zero, decent battery consumption, and seem to be durable.
  • Easy operation and quality is very nice!!! Only draw back is battery life compared to Aimpoint.
  • The only beef is, and this was an assumption on my part, based on the shape of the battery tube, I thought it would have used AA or AAA batteries.
