Not bad - NC Star 3-9x42mm Rubber Armored Mark III Tactical Rifle Scope

Mounted on a m4 carbine. It's an ok scope for the range. I wouldn't expect it to last in harsh conditions. The illuminated part lights up the whole inside of the scope when it decides to work. wiggling the knob makes the light flicker on and off. It sits low and I had to replace my rear sight with a shorter one. actual eye relief is questionable, I end up closer than it claims. otherwise it looks cool. reminds me that "You get what you pay for".
Pros: easily attaches, compact, looks good, easily attaches
Cons: cheaply made
