U.S. Optics SN-3 T-PAL 1.8-10×37 Scope

U.S. Optics SN-3 T-PAL 1.8-10×37 Scope

The optics mounted on 702 Shooter’s Precision AR Raffle Rifle is the U.S. Optics SN-3 T-PAL 1.8-10×37 Scope, first focal plane, with a 30mm tube set into their 30mm P6M-3000 rings and mounted to the picatinny rail on a flat-top LAR Grizzly OPS-4 Upper Receiver.  The mounting was very strong and held the scope at nice height for the AR platform.  The adjustable cheek on the Magpul PRS-BLK stock made for a sturdy, repeatable shooting posture.

Ahh, to finally get behind a U.S. Optics scope, I’ve looked through them on other’s rifles, fondled them at the gun show tables, and now I had the opportunity to use the equipment as it’s meant to be used.  In the dust, wind, and firing rounds down range.  It’s too bad my wife won’t let me buy one; this is a nice piece of kit.

I found the eye relief to be a little close, but manageable, and once I had laid eyes behind it a few time it became very natural.  The glass is remarkably clear with no distortion or haloing, and the scope maintained this clarity throughout the magnification range.   The first focal plane is standard with USO scopes, allowing the user to make windage and elevation corrections accurately from any magnification.  It does tend to scrunch up the reticle scale a bit when dialed all the way down, but if you focus it is still usable.

Mil Scale GAP Reticle

The Mil Scale GAP reticle was clearly marked and easy to read.  I like how the mils were marked out with numbers on the scale, it takes the guess work and counting right out of adjustments.  The reticle illumination feature is nice, and one I never appreciated until I found myself doing a bit of low light shooting, well, actually pitch black dark with lights on the target.  Without the reticle illumination you might as well throw rocks.  The illumination control is forward of the windage knob on the right side of the scope, and has nine positive clicks to control the brightness.

Ilumination & Windage

The windage knob is the U. S. #3 on the right side behind the illumination control.   It’s easy to reach and has a nifty feature known to USO as windage stop.  This prevents the windage adjustment from going past a 180 degree turn, which can be a serious bummer when you loose track of where you are at in windage without the stop.  Most time you’re headed back to re-zero the weapon.  The scale is clearly marked in 1/10 mils.

EREK Control

The crowning control is the Erector Repositioning Elevation Knob (EREK) for elevation control.  The EREK gives the scope a very low profile and gives the shooter a very large knob to get a hold of and provides 90 positive 1/10 mil clicks in one revolution. The parallax adjustment is on the right side of the scope tube.  The knob movement is very smooth, allowing the shooter to bring the target into a nice crisp focus. If you are wondering what parallax is, USO has provided a nice explanation on their web site about parallax.

The U. S. Optics SN-3 T-Pal is a low profile, highly functional scope that is a perfect match with the AR platform.  Dialing it down to the 1.8 magnification provides a 42 foot wide field of view for close work, and when dialed out to 10 power younger eyes can shoot out to 800 plus meters easily.  True to USO’s reputation, this is a scope to take into any field conditions to get the job done.
