Well worth the money - UTG Pro 4.2in ITA CQB Reflex Micro Red Dot Sight w/ Integral QD Mount

This sight worked out perfectly for me. Was very surprised because it was inexpensive it's definitely worth the money. I put right on to the rail of my Mossberg 930 SPX and it only took a matter of minutes to have it zeroed in for 40 yards. It's great if your using it for slugs and 00 buck. I like the red dot green dot feature a lot. Even with all the vibration from the shotgun I have no problem at all with that sight. It's comes complete with batteries and a alen key, every thing you need is right their.
