I am in the market for a couple of red dots. I am looking to add two to two of my AR's and one to my x95. I'm looking for something that wont break the bank right now. I may get an MRO or a Holosun 512c for my x95 at some point.
What is the difference between the dots listed below?
Vortex Sparc.
Vortex Sparc II.
Vortex Crossfire II
And are those optics listed above about the same as the optics listed below?
Holosun HS403B.
Sig Romeo 5.
I'm looking for something that will take a beating and keep on ticking. I want long battery life too. I watched a video on the Romeo 5 where someone shot it with a shotgun. It took the blast and kept going. That was impressive. I know the HS403B is the same optic as the Romeo. I like Vortex warranty. Its impressive that a company gives that. I just don't know much about their red dots.

In reference to your first question, none of our red dots are the same optics as the others you mentioned.
The "SPARC" without any other designation is quite old and outdated. At this point in time, most all of them are off the market and have at least been replaced with "SPARC II's" at this point, which were a long standing micro red dot for us that performed quite well. It was also very durable, as noted here in this Recoil article -
The Dot That Would Not DieThe SPARC AR, which might have been what you were referring to there, is a much more streamlined version specific to AR's or other carbines. Everything control-wise is in the integral base, so nothing sticks off the side or top of the sight. Functionally, it is nearly identical to the SPARC II, though, other than running on a AAA battery rather than a CR2032 and also having much better battery life at 50k hours
Crossfire (We don't designate the red dot as a "Crossfire II" FWIW) - Again, functionally the same as the SPARC AR and SPARC II internally (Not identical, but for all intents and purposes) but has a rotary dial switch on the side for changing illumination intensity which houses its CR2032 battery. Also gets 50k hour battery life. The base on the Crossfire is also removable if you want to run it on something other than an AR.
There is a new optic in our lineup as of just a week or two ago called the "SPARC Solar" which is very much a different optic all around. Internals have been upgraded to offer up a wider FOV through the optic and a really nice image (Parallax free, flat image, minimal tint, etc) and as the name implies, it has a solar panel on the top which actually runs the sight off ambient light to dramatically improve battery life. When there isn't enough ambient light to power the sight, it uses the CR-2032 battery on board. Illumination controls are done via side digital buttons and the turrets are a new design that are completely flush to the body and entirely snag free. It also has a removable base to mount on basically any platform.
There may be other reviews on each one of these listed above to prove durability (Likely not yet on the SPARC Solar) but the thing is - that SPARC II which underwent the beating in the recoil magazine was an older red dot all around with not nearly as many nice new updates as the others have gotten since then that actually would improve durability even still quite a bit more. None of these optics should have any issue getting beat on even a great deal.
Hope this helps.
