US Optics SN-3 T-Pal 3.2-17x44mm

The SN-3 3.2-17x44mm T-Pal is a variable magnification rifle scope from US Optics. The scope features first focal plane, a 30mm main tube, 44mm objective and side parallax adjustment as standard options. During the short time I have been using the SN-3 I have been very impressed. The scope is very robust and made to handle the harshest conditions. US Optics rifle scopes are very prevalent within the military, law enforcement and competitive shooting communities. The staff at US Optics is very knowledgeable and experienced and they were very helpful when selecting features that would best suit my needs. Jason Kyle did an excellent job explaining the pros and cons of different models and options and with Jason’s help I was able to put together what I felt was the perfect scope for my rifle

I chose the SN-3 3.2-17x44mm T-Pal because I felt it was a very practical magnification range for the rifle matches and long range shooting that we do. I like having the TPAL option(TPAL stands for “Turret Parallax” as opposed to their “ERGO” offering, which places the parallax adjustment up at the objective of the scope) of  parallax adjustment on the scope turret housing because it’s easy for me to adjust from different shooting positions. The glass quality is excellent and I was very impressed by the clarity. The reticle is located on the first focal plane so that it scales with the magnification, keeping the sub tensions at a constant value.  On the lower magnifications it can be hard to use the 1 MOA marks but the larger 5 MOA and 10 MOA marks make the reticle usable while greatly increasing your field of view. I’ve wanted to make the change to FFP for some time now because I feel it’s the best choice for the type of shooting I do.

I like to use minute of angle (MOA/MOA). I selected the CMG MOA reticleEREK 1/4 MOA elevation knoband US #1 ¼ MOA windage knob. I like the EREK knob because it’s a fast turn knob allowing 22.5 MOA of elevation per turn allowing me to shoot out to 900+ yards within one turn of the knob. The clicks are very positive and once you set the EREK knob it allows you to take advantage of all the elevation travel of the erector so you don’t have to worry about how much you’ll have left after mounting and zeroing the scope. The EREK knob also incorporates a zero stop which I have found to be very useful. I chose the US #1 ¼ MOA windage knob because it’s easy to manipulate and you can use an optional cap to protect against ejecting brass as well as being bumped or rotated inadvertently while stowed in a drag bag or moving from stage to stage or position to position during a match. Having the turrets and reticle use the same unit of measurement is very important. It allows you to make adjustments to the scope based on what you see in the reticle, without having to do conversions in your head. Many scopes feature a mil based reticles with minute of angle turrets. If you use the reticle to make adjustments you have to convert mils into minutes of angle to dial the scope correctly, and while many people have taught themselves to make these calculations in their heads, we feel that is simply makes more sense to keep everything consistent across the board.

The internal anti cant device is awesome and I suggest that anyone looking to purchase a US Optics scope should add it to their build. You can also have the option added to existing US Optics rifle scopes by sending them in to the shop for a retro-fit. I have used a fixed anti cant device up until now and it has worked fairly well for me, the procedure would be as follows:  Before I got ready to take a shot I would have a peek with my non-dominate eye to make sure the rifle is level, then I would look down the scope and begin establishing a sight picture…  With the US Optics internal ACD option, the level is located inside the body of the scope. You can easily see the level at the bottom of your sight picture so everything you need is right in front of you. Having an internal ACD also makes it easy to mount an angle cosine indicator to your rifle without cluttering up your rail, if you so choose.

The 30mm tube is a standard option and I decided to stay with 30mm because it allows the scope to be mounted low and close to the bore of my rifle. It wasn’t so long ago when the standard industry tube size was 1” and 30mm was the optional larger tube. Now you can select 30mm, 34mm and 35mm tube diameters, with the larger tube diameters allowing for more internal elevation and windage adjustment.US Optics produces high quality rings for all different main tube sizes, so you don’t have to worry about finding rings to mount your scope if you select an oversized main tube.

We don’t shoot at night very often but when we do, the illumination feature is invaluable. When shooting in low light the illumination feature lights the reticle so it contrasts from the background. You can select two different colors for a US Optics build: red or green. I chose red because that’s what I’m accustom to and it’s supposed to be easy on your eyes natural night vision, however I’ve heard from other shooters that the green does an excellent job as well. My scope utilizes the new digital push-button illumination controls, which replace the conventional rotational rheostat that is also available.  The illumination control is located on the right side of the scope and has 11 different brightness settings. You use the up and down buttons to select the intensity you desire, and once you turn the illumination off the setting is saved and will remain there once you turn it back on. This feature is really growing on me and US Optics is one of the few scope makers who offer it.

My over all experience with US Optics has been extremely positive, from the people to the end product. The quality, durability and innovation makeUS Optics a stand out, and they were recently certified to ISO 9001:2008. Through an intense audit process US Optics was recognized for its quality management system that supports their quality objectives.

Everything adds up to be the most impressive rifle scope I’ve used in my short lifetime. You can completely customize the model that you chose for your specific application. You can have everything you want, nothing you don’t and some things you didn’t know you wanted. I look forward to continuing on with this scope. I have been very pleased and look forward to more innovations and technological advancements from US Optics!
