I think all the guys post their comments above are complete wrong, C-More makes one of the best red dot scope in the world.
some of the best features are:
1. needs to remove the sight ot change batteries, this way you can have more experience sighting in your gun every time your battery ran out.
2. Low battery life, so you have more chance to familiarize your rifle by doing zero check to ensure a proper zero.
3. The red dot project itself from muzzle side, especially at night, so you give your enemies a fighting chance since you do have the best red dot optic in the world so you just want to be fair and give the poor guy a chance to see you before you shoot him dead.
4. The adjustment knob for zero is very hard to adjust, it does not have any clicks and many time when you lock it down the knob would shift and push the reticle out of zero. this is a good excerise to build your patience.
5. The objective glass can be snap off if you experience a hard impact, this will make you sharpen your iron sight skill.
By buying a C-More, you will have a lot of chance to practice you french too.
Hope this helps.
P.S. I must be bored on a Sunday afternoon.
