Looking for best RDS options for an SPR-type rifle setup, which has a 2.5-10x optic, and will wear an offset RDS.
I have an Aimpoint T2 and an Arisaka offset mount on another rifle. Like that combo for the unrivaled durability and battery life; it works fine. But not sure I want to add another T2. Not only are they pricey for an RDS, but with my astigmatism I get a significantly less crisp dot despite trying the tricks of the trade to improve clarity (reducing brightness, looking through cowitnessed rear sight aperture, using/not-using my corrected lens glasses, etc). And though they are not heavy by anybody's definition, the T2 are a good bit heavier than today's super-compact pistol mounted RDS.
What are other strong RDS contenders that folks have found to work in this role? Criteria: a durable/proven RDS, weight of 2 oz or less, uses a common footprint (so I can mount on offsets like Arisaka or Badger J-arm), and gives a 2 MOA dot that is as clear as the T2 (or better). Closed emitter is a bonus, but optional.
A few on my list:
* Holosun 407C/507C, or EPS (not carry). These would work with RMR footprint offset mounts. All of them are light, and I have these optics on pistols, I can actually see the 2 MOA dots more crisp than my T2. If I go with an EPS, I'd have to use the included RMR adapter plant to attach to an offset RMR footprint mount.
* Trijicon RMR. Issue here is no 2 MOA dot option, that I'm aware of. They have a 1 MOA, or 3.25 next size up. Does the 3.25 MOA work well enough for ranges within 50y?
* Other?
