Slight thread jack: any word on a Sparc type model with increased battery life being worked on? As it stands, the Sparc needs a change of batteries every 3 months or so instead of 3 years or more on an aimpoint. From the looks of things they are quite durable, but the electronics aren't advanced enough.
If Holosun and Primary Arms can do it, surely Vortex can figure it out. Then put it on the same plan as an Aimpoint micro and I'd buy one just to find out what it takes to break it.
