Sightron S-Tac 2.5-17.5x56?

Hi all.
Long time reader (great forum!!) but only just found something to ask, so please be gentle with me.

So, has anyone got one of Sightrons new 2.5-17.5x56 scopes and is it as good as I'm hoping?

That's all I got to say

The scope weighs too much for my style of backpack hunting. 30.6 oz. But it could be a pretty nice option if you're young or not backpack hunting. That's a nice, covers most needs, power magnification range.

Even their 6-24x50mm SIIIs are now listed at 24 oz. They used to list the weight as 21.9 oz - as I remember. I own three of their 6x24x50mm SIIIs. They must have increased the thickness of their 30 mm aluminum scope tubes on the 30 mm SIII scopes. Better for strength and toughness, but getting pretty heavy for backpacking.

I've been hoping for a 4-16x50mm for several years now in their SIII series. Not happening so far. It's either 3.5x10 or all the way up to 6x24 variable powers.

I happened to notice this retailer showing they have them in stock...
Sightron Riflescopes, SIII Tactical Riflescopes

I'd also like to see some feedback on the S-Tac scopes. They weigh too much for my personal use and interest.

I spoke with liberty optics and they said this is a great scope. About half of the first production batch had problems with tracking but the problem has been fixed and the new scopes should have no problems.

Re: Sightron S-Tac 2.5-17.5x56?

Anybody have personal experience with the S Tac scopes ?

I have done all the utube/ web surfing and just want opinions from the users..

I currently have the Slll 6-24x and the glass is superior compared to my 2 Vortex PST's and 1 HST scopes, especially when cranked to the highest power !
looking at the low power setting of 2.5 and 56mm objective this baby gonna be bright, and still have the high mag setting (17.5X) for longer range pokes... weight is not an issue as this is an atv/gunboot to location type of hunt

anybody ?

will have a new in box Vortex HST 4-16x VRMOA up for sale if I pull the trigger on the S Tac
How is it y'all still don't know the difference between CALIBER and CARTRIDGE ??

Check out the Burris XTRll scopes, much much better glass than the Vortex Pst.
