I did a side by side comparison between the SPARC and my Primary ARMS red dot. I've also had a chance to do the same comparison with the vortexx strikefire. These would be my notes, and it's not the first time I posted this either:

1. PA Dot brightness is superior to SPARC
2. Both equally hold zero on real guns.
3. SPARC feels less durable
4. After spiking my PA into a concrete parking lot like a football 5 times, PA still hold zero on live fire. SPARC owner refused to perform the same 'test'.
5. PA is 1/2 to 1/3 the price
6. SPARC glass is marginally better than PA. IMO <20% difference
7. I've left my PA on in the gun safe for 6-8 weeks at a time and the battery has not died. I assume the SPARC has a comparable battery life.

If you can find the means to get yourself a PA do it. It's far better value for the dollar. That being said the SPARC is a good RDS
