I have a very slightly used Taiga. It has been on my gun for a total of 50 rounds. I have done all the modified so that it will fit on a flattop. I'm changing my AR configuration to a "sniper" role and a 2.5 magnification just is not going to cut it.
The Taiga, has a -^- sight(the inverted V is actually lower) instead of a regular red dot. You can screw the rear lens off for a standard red dot sight and if you put the rear lens back on, it will magnify the image 2.5 times. Email me at JustaBlokeAnywhere@hotmail.com for pics.
Am selling the Taiga for $75 shipped, includes extra batteries. Kalinka Optics sells them new for $99.97 new (not including shipping, or batteries) with a one month wait (despite what they say, they ship it from St. Petersberg, Russia and not from their US warehouse). Price is firm as the unit is pretty darn new.
