Description
Trijicon ACOG TA11 3.5×35 Riflescope, Red .223 Donut Reticle, Black
The Trijicon ACOG TA11 is the 3.5×35 model with a red donut reticle calibrated for .223/5.56. The open-center ring gives this version a different sight picture from the chevron, horseshoe and crosshair options in the TA11 family.
This configuration has an M16/AR15 carry-handle base. It is not the TA51-equipped flattop package, so the mounting arrangement is an important distinction when comparing models. The scope weighs 14 ounces and has a matte-black forged-aluminum housing.
Fiber optics and tritium illuminate the reticle without batteries. Ambient light controls the daytime brightness, with tritium supplying illumination in low light. Fixed 3.5x optics provide 2.4 inches of eye relief and a 28.9-foot field of view at 100 yards, while multicoated lenses and nitrogen filling help maintain a clear, fog-resistant view.
