Not so bad after all - Troy Micro Set M4 Top Mounted Deployable Iron Sight

I gave it a 4 because i actually need to purchase a sight tool to zero it solid. You can only get so far with a bullet or regular tools. Rear sight came loose during zeroing in. Make sure to use the lock tight as reccommended by manufacturer. Also why I gave it a 4. Not good in dark or low light conditions. Get the Tritiums which were my first choice, however they were sold out. 3 month wait and during this Global Epidemic situation I had to choice but to get these. Once I zero'ed them in they were rock star. Low Profile. Solid construction. These are REAL and not imposters. I checked and these are legit Made in USA. Very Happy with them. Wish I had those tritiums.
