Since purchasing a 8-32x56mm SIII, Every time I see a thread about Sightron I feel compelled to chime in as I don't believe they get the feedback and hype they deserve. Mine has the LRMOA-2 reticle and I'm very happy with it. In my eyes they are a great value, having one of the best combinations of well made glass, turrets, and reticles in a higher power variable for < $1,000.
Steve, from Sightron is very helpful and has always been happy to offer advice and answer questions regarding their products.
To my eyes, Sighton's glass produces a great image with high resolution thats very natural looking (color wise). Again, to my eyes... it outshines its competition from Leupold, Bushnell Elite, and several others in its price range. From consensus, I hear most agree that it favors well when compared to Nightforce (optically only of course). It's not the end all of scopes in its range, but for what is offered is done very well. Bushnell or Vortex for example, offer more and different features than what's available in the SIII series. I own an Elite Tactical as well and they both serve their purpose. If you like one of the Sightron's reticles and only require a slim set of features, the SIII would be a great choice.
The SIII series now has a total of 11 different reticle offerings:
3 Moa variants- 2 dedicated for illumination, 1 offered illuminated (IRMoa-2, IRMoa-3, IRMoa-4, LRMoa)
4 Mil Variants- 2 dedicated for illumination, (Modified mil dot, mil dot, il mil hash, il silhouette)
4 Crosshair/ dot type- 1 dedicated for illumination (IR4a, LRFCH 'fine cross hair', LRD, LRTD
All Sightron scopes are SFP and ranging reticles come with sub tension sheet for every magnification.
All Sightron scopes are True 'top' and 'bottom' magnifications that are listed (no 8.13x...), for accurate ranging
All SIII scopes are made in Japan
All Turrets are offered to match reticle, the standard mil reticle can be accompanied by moa or mil turrets
All LR SIII scopes can have custom parallax settings made
High mag models have option of fine/coarse mil and moa turrets: .25 & .125 moa, .10 & .05 mil
Sightron is opening a custom shop to offer reticle and turret swaps
Personally, I think they're a great company. I believe from my last discussion with them they mentioned celebrating 25 years in business. They don't offer anything FFP or with zero stop but if seeking a SFP scope for target I believe you get what you pay for. It would be nice if they offered some additional features down the road but as of now you pay for great glass, nice turrets a simple but purposeful reticle.
Here's a link below to a thread I started about this scope. It has some pics and comments from other SIII owners as well.
