I have both and much prefer the Sparc. It is a better design, with more features and adjustable risers. Co-witness' with ar sights, has magnification as well. I find the bushnell is too low for me and also looks like a cheaper made optic. It has seemed to function well but I would rather the SPARC any day plus vortex has great customer service, bushnell service is also really good too but much slower, they have only 3 repair techs that have to service all of the Tasco, Simmons, Bushnell products so it is a min. time of 3 months but more likely longer.
