Photo Of The Day: Above we have the United States Army Squad Designated Marksman Rifle M110A1 (SDMR). But take a closer look, there’s something unusual going on. If you look at the optic you’ll see it’s from Vortex rather than SIG Sauer.

The mount seems to be from Geissele, with a Reptilia Trijicon RMR mount on top. Is it the shooter’s own Vortex, and why bring it to the Bemowo Piskie Training Area in Poland? Or is there some benchmark testing going on? I guess we’ll never know, but feel free to speculate in the comments below.

With the ongoing war in Ukraine, I think these soldiers can feel the heat even in Poland.

U.S. Soldiers assigned to 1st Battalion, 185th Infantry Regiment zero their weapons at Bemowo Piskie Training Area, Poland, March 11, 2022. As part of the NATO mission and presence, the 1-185 is consistently contributing to the NATO enhanced Forward Presence mission in Poland.

Check back tomorrow for another run of our Photo Of The Day. We’re always on the lookout for the best firearms-related images out there, with the goal to give your eyes something worth watching every day.
