Introduction
Steiner is a very well-respected brand with deep roots in the shooting community. So it was with great anticipation that I jumped on the opportunity to check out the Steiner T6Xi 2.5-15 riflescope. I had recently reviewed this scope’s big brother the 5-30 version, so I was excited to see if the smallest member of the T6 family stood out.
I am nothing if not a long-range rifle junkie, so nerding out over another beautiful little riflescope is right up my alley. It’s been one of my pastimes for the last few decades.

The Steiner T6Xi
Our adventure today involves the smallest child of the T6 family, there is also a 3-18 and the aforementioned 5-30 model. With a little luck perhaps I’ll get hands on the middle model as well. But for now let’s get a good look at the 2.5-15.
The T6Xi 2.5-15 is based on a 34mm tube, which has become the popular option with long-range precision shooters. Up front you will find a 56mm objective lens to draw in as much light as possible for a bright image. The scope has a fairly squatty appearance, looking a bit short. But this is a welcome feature for many of the compact rifles that this scope will be mounted to.
And though Steiner scopes are built for rugged duty, the smaller size will also reduce weight.
At the center of the scope you will find the same basic erector assembly as the other T6Xi scopes. The T6 family has a very intuitive and genius turret system, the numbers are underneath the turret and change when going from the first turn to the second. Revealing second rotation numbers means there is never any question as to what revolution you are on.

The high volume of motion on tactical scopes often requires some way to confirm what revolution of the turret you are on, and this design is a fantastic way to accomplish it. There is also a cunning turret lock design that prevents unwanted rotation of your turrets.

On the Range
With the stubby little Steiner mounted to my Taurus Expedition .308 rifle, I headed into the hills to give the combination a workout. I must start by saying that I love medium-power riflescopes. Scopes that aren’t pushing for such high magnification always seem to be so clear and bright.
I’d mounted the scope in a set of 34mm rings, and I found one thing that was just slightly irritating. Due to the small size of the T6, you don’t have a lot of wiggle room when it comes to mounting. Not a big deal, but it may require you to be very deliberate in your mounting solution.

After zeroing the scope to the rifle, I reset the turrets at zero. This is done by loosening the two screws of each turret and rotating the turret back to zero. This design keeps the turret body affixed to the erector hub, making for a robust construction.
The turret locks are quite interesting. The top of each turret has a locking ring you can turn to engage or disengage. In the locked position you can see a “locked” indicator, and when unlocked you will see an accompanying “unlocked” indicator. This feature adds to a stronger turret structure. Many turrets are lifted to unlock and pushed down to lock, but the design of the T6 seems stronger as the turrets are secured in place and not meant to move up or down.
Shooting the Steiner T6Xi
With the scope ready for action, I began picking out targets across the canyon in evening light. Many of my usual targets popped out in the yellow light. I gripped the parallax adjustment, turning slightly to better pick out my targets.
