Little bigger than I thought but very acceptable. Come with rubber 1 piece lens covers & sun shield. Etched reticle, also illuminates red & green with 4 different brightness levels for each. Even in the bright sun, the highest level seemed more than adequate to be easily seen. Removable mount attaches solid. Mount can be removed & optic will supposedly attach to any acog mount & some others if desired. Glass seems to be great quality & clear with 0 distortion. Unit felt heavier than i thought it be for being constructed out of aluminium, but picking up the rifle one armed, with & without the optic mounted, I noticed no difference. I'll provide more details when I get to the range to test it out. Found I can hold the rifle upside down & charge it with my good arm, so gonna try to get out with it once pain levels improve from stranger arm surgery. So, over all I'm happy with it so far. The important test will be live fire performance.
The off set flip up sight I purchased were a no go(for me) . Puts my face too close for my personal taste to the ejection port for comfort. The sights did seem solid & well constructed, mounted solid to the rifle. I'll find a more adequate solution later. For now, I added a Bushnell 1st Strike mini red dot atop the Wolfhound optic.
