I am pleased to read the debate going on here... some good points, some not so accurate points.
www.sightronusa.com for all the scope specs and product offerings.
So let's look at the products and where things are going as I know it...
Sightron is greatly reducing their 1" tube scopes. Sorry, but the SII and SIIB are on life support. In fact, most of the SIIB are now gone.
As their entry level 1" products, the SIH is it. First ones were BLAH.... current ones are crazy good for the entry level price. Surprisingly good glass, tracking and features. Obviously, leaning on lower tech but all of it is useable and for those on a really tight budget, you get a scope that works. For those with package rifle and those "scopes", if you want to improve but on a really limited budget, the SIH family will get it done.
Better eye box, eye relief, field of view and useable glass... I have yet to see anything at this price point remotely close.
STAC... ok, CanuckR is completely accurate in that NONE of these scopes fit the "tactical" mold. What lives here are superb PREDATOR, LR hunting, low light, close range hunting scopes. The line up would have been better served with say a "predator" or "alpine" moniker. All are 30mm which at this price point is a great feature. Most of the SIII goodness is packed into these scopes put together in the Phillipines where the cost of manf is far lower then Japan. Yeah, yeah, I can hear the Phillipines comments coming... sorry, robots and CNC mills don't care where their factory is based.
these are featured filled scopes that really answer the question from the specialty HUNTING market from around world. Yep, the STAC 2.5-17.5X56 was not designed for the NA market... it was the low light, lamp light hunting done elsewhere. It doesn't take much light to put your target in view.... very impressive. Not as relevant for the rules we hunt here but if you really need a low light scope, worth a consideration.
The 1-7X20 is one of the few true 1X variable scopes... yep, I can see and aim at my feet at 1X. 7X can quarter a Fig 11 at 600m.
Two new ones from last season have been a home run. The 4-20X50 is the most popular as many want a higher mag scope but not over $1k price. Lots of desired features, solid optics and tracking... users have been reporting their positive results in many places including this post. PD hunting at LR would be a natural for this scope.
My fave is the 3-16X42... small and compact of a standard hunting 3X9 but all the features you would want in a predator and LR hunting scope. At 3X, door knob across a room is an easy target. 16X, no problem to engage MOA sized targets out beyond 1000yds. Whether calling in a 'yote or picking off an elk across a canyon, the features are the most asked for over the last many years. Sightron did listen and now you have an amazing product for cheap.
On a clear day, I can put the central dot of the LRMOA reticle on an exterior door knob of a house just over 1000yds away. Capped target turrets, my fave LRMOA reticle, side focus, big easy to use eyebox. This is the scope I am currently playing with as I learn the PRS positional shooting stuff.
SIIIs haven't changed much since they came out... new reticles, a few new features but nothing radical. For the money, amazing glass, solid tracking and has been on podiums in various LR shooting sports including 50 BMGs and F class rigs. The scopes these compete with are 50 to 100% more money.
I wished they would try and diversify into the tactical arena.. and maybe they will. Keep bugging Sightron, they may be slow to react BUT they do listen and with enough interest, offer what we want.
But for now, the specialty hunting, LR shooting and square range competition markets is where they are at and for the money spent, it is hard to find anything comparable.
YMMV
